Zel's Motoring Adventures...Citroen, Merc, VW, AC Model 70 & A Sinclair C5 - 21/06 - The Case of the Hidden Thermostat...

Generally I've found most of the van bits on the camper to be very easy to service.  Though I appear to have found the exception that proves the rule.

Our mission today was to change the thermostat.  I'm pretty sure the one fitted has been stuck open as long as I've had the van.  Heater gets to furnace levels in the winter so it's not running cold, cold but the gauge never really moves more than 1/16" from the bottom other than on hills.

Passenger seat out, dog house off and we have - just about buried under the fuel system - visual contact with the head.

The casting the top hose goes into though doesn't look even close to big enough to hold the thermostat - which is a moderately sizeable one.

A bit of head scratching and standing on my head appears to have located it, rather oddly kit seems to be at the engine end of the *bottom* radiator hose.

Odd setup...and not exactly easy to get to.  It's sandwiched between the exhaust manifold and offside engine mount, tucked behind the alternator which precludes any thoughts of access from the front.

Near as dammit the lowest point in the system too so definitely be a coolant drain as step one... inevitably I'm going to end up with several litres of coolant in the face doing this job though!

May end up being a case of "screw this, a garage can do it!" depending on how awkward access ends up really being when I try to get tools onto it.

Need to clean the whole area up too as the timing cover gasket appears to be leaking to no small amount again.

Will probably blast this area down with degreaser then hit it with the pressure washer first though as I'd like to confirm if this is coming from the timing cover or oil filler neck extension (bolted to the timing chain cover as in the van application the normal filler is inaccessible) before I go blowing £30 on another gasket for the timing cover.

That combined with running several errands however has consumed my available energy reserves (and patience with being eaten alive by ants), so back hiding in the air conditioning for now.

Tiny job done this afternoon...getting rid of these sun-baked and flaking off stickers on the Caddy's front windows.

The passenger side one was horribly wonky too which was bugging me.

IMG_20220627_164753.thumb.jpg.a245e93cc3197a6bacdafcf18535a16e.jpg

It was also peeling away and causing the window to bind up.

Got rid of these ones at the same time.

I really hate stuff like this so surprised it took me this long.

Much better.

Can't remember who it was that suggested to me using WD40 to get rid of sticky residue on things a while ago, but I'm really glad they made the suggestion.  The goop left behind by them just wiped straight off with it pretty much.  Normal glass cleaner then gets rid of any residue from the WD40 easy enough.

      Having fetched this French delight from deepest, darkest Norfolk (well Norwich actually) in an underwhelming collection, for no other reason than the van was scooped up onto a trailer for its journey home, it was time to see what was needed.
       
      I knew a RH side load door was needed, luckily an item was procured for £20 from a guy breaking a Scudo. I drove across to Swadlincote in the van and it proved to drive well, as expected from wuvvum’s write up. On the way home it started surging when the fuel level dropped below quarter on the gauge, again as expected.
       
      Door was fitted and adjusted on return, it was even the same colour!
       
      During the week I looked at the rear doors and fettled and adjusted the locks / latches.
       
      Today I dropped the fuel tank and found a loose baffle, along with crud in the fuel pick up / tank unit. A road test will be the proof of this repair.
       
      I also achieved a working temperature gauge today and changed the power steering fluid out.
       
      The to do list includes a coolant flush, new tyres (cracked side walls), new discs and pads, LH door slider and lock handle, a deep interior clean and removal of the ladder rack. In the meantime have some photos.

      Been a serial lurker and occasional poster of nonsense, but have never quite got round to posting some pictures and the ongoing tribulations of being a serial VW licker.
      First a disclaimer - I like old VWs, partly as I grew up with them and partly because I understand how the work and I can fix* them. I do not like the 'scene' attached to them, it seems to attract too many of a certain type of person I am often allergic to - they bring me out in a shouty rage. 
      First car was a'69 beetle in red, driven flat out everywhere  until the rust took it. This was followed by a succession of Mk2 golf , vauxhall omega (vauxhall being close to VW in the sales ads)  a free Mk3 golf which was dire and tried to kill me multiple times. I have no photos of any of these as they were pre-camera phone and mostly awful. 
      Then came a T25 camper bought using generous donations from friends and family at our wedding . Bought, and a week later after hovering 15 years of dog hair out of it, we drove it all the way to northern Norway on honeymoon. Used it for a while.
      Bought a vauxhall astra estate (again, it was almost a VW in the sales section). It sucked. It did a year of commuting then it was scrapped. Was gifted a skoda fabia estate by my dad as a sensible run around. 
      During this time my wife wanted a sensible runaround for her and the kids, so we bought a bright orange 1971 beetle (rusty of course) which was excellent fun. People were openly critical of apparent lack of regard for our offsprings safety. I pointed out it had seat belts.
       Due to rusting the T25 was sold as a project, the Skoda was sold for being too dull and a T2 purchased.
      Here is the peak of VW ownership, where the beetle, bay and T25 are all in one place just before sale:

      So now we had two aircooled vehicles, the newest of which was  made in 1973.
      This lasted for exactly 9 months., during which I did lots of this:

      to be repeatedly rewarded with this:
       
      When the breakdown driver asks how the kids are getting on, you know you've seen him too much....
      I also conducted some invisible repairs on the rusty bits of the beetle. I'll point them out if anyone can't see them:

      A promotion and car allowance then allowed me to purchase a C3 Picasso (best not ask, I hate it). Its purple. I feel like a dick when I drive it. 
      Beetle then had to go due to third child and not enough seats, but it had the good engine, the van did not. A swap occurred. My neighbors love* me and find my antics endearing*. I clearly have no need for a drive or garage.

      After 1 too many FTPs, I was told van or family. I chose family and the van left. 
      I then went a looked at another T25 minibus (three kids now) and was in much trouble for even considering another van. 
      Two weeks later, after some small* arguments* we were in total agreement* and the van was purchased. 
      Roughly 18 months ago - note lovely laqueer peel, mismatched rear wing and low level tide mark:

       

      After some light fiddling I have made a very basic day van affair, and we dragged it with camping gear and the three kids all the way up to the arctic circle in Finland last summer (wife has family in that part of the world).
      6 days before departure I noticed the rear suspension had a bit of paint hanging off. I pulled and it showed this below:

       
      Trip to machine mart, a google of "mig wleding for numpties" and a youtube video later and I'd made this:

      and away we went. 
      Here it is in a moody B&W photo  in the land of the midnight sun, which really brings out the high quality paint. the rear suspension is still attached though, so winning. 
       
      That's an epic catch up post really, but will use this space now to document the exciting* repairs and work done on it to keep everything attached .and working....

      I think the Broadsword fleet has become sufficiently complicated to merit a combined thread so that gradually all new additions will appear in one place.
       
      As of Sunday 17th March the situation is interesting.
       
      Two Citoren Xantias (remember the white Xantia of Excellence is for sale people!)

      A turquoise XJR6 pending overdue-collection (need that gone now!)

      An XJS 3.6 manual project which will get in high gear soonish. Wont be a keeper but will be fun getting it back to something presentable. Drivers fantastic!
      http://autoshite.com/topic/34664-jaguar-xjs-36-manual
       
      A Range Rover P38, which is turning out to be really rather good.
       
      And to mix things up even more I'm off on a collection caper today. Had first refusal on it and was expecting it to come around in a year, but things soon changed and no way was I going to pass up on it. It may well render the second Xantia redundant as I've got a really good feeling about this motor.
       
      In the meantime here are some snaps of the Range Rover. As usual it was a car I said I would probably never buy due to their reliability*. I have said the same of Jag XJR, XJS, XK8 and I have had all of those now. Basically the moment I declare buying a particular car is impractical or improbable, I end up buying one.
       
      Things to note on the P38. It's a nice colour with tidy body. The EAS has been removed. It runs and drives lovely and it doesn't have enough electrical problems to hinder progress. The main one is the driver's side window not working, but that should be fixable. I've tried changing the outstation, that didn't fix it. Might be wiring under the seat. Other than that I bought it and took it for an MOT the very next day, and it passed. Since then it had what seemed like a battery drain, but since unplugging the RF thingy for the remote locking and putting on a proper lead-acid battery, which the car can actually charge, unlike the modern lead-calcium batteries, it has been perfect. I will treat it to a full service soon.
       
      Stay tuned for the latest collection later today!

      First some background:
      I was brought up with no car interest, a car was transport and nothing more which resulted in a selection of poor cheap cars being the cars of my youth.
       
      Fast forward many years (just over 9 years ago) and I have a wonderful* Vauxhall Vectra estate to carry us about. Unfortunately it is crap and throws fault codes at us with nothing being there when it is checked (even at Vauxhall)
       
      As Mrs T is the main pilot of this chariot with the two little miss T's on board, it has to go.
      The hunt is on for the new steed to safely and comfortably carry the family around. I have a company car at the time so big journeys are not an issue.
       
      ebay is my weapon of choice to find the new family car. It has to be good value cheap for no other reason than I am tight.
       
      Weeks of research with lots of cars that are too expensive and too far away for easy collection end up in my watch list.
      Finally a possible is spotted in Fife. I go and have a look and find a poor looking but solid car. One previous owner and lots of history.
       
      The auction was to end on the Saturday at midday, we were going to be out! I decided on how much I was willing to gamble on it and on the Saturday morning I put in my max bid but straight away it went to my max bid, I was winning but it had three hours to go with no room for me to go up! We went out anyway.
       
      I spent the next three hours kicking myself for not bidding more while we were out as it was the first car I had seen that fitted my criteria. Fate was in charge.

      On returning home I go straight on ebay to find 'Congratulations.............'
      For the grand total of £500 I had just won this fine vehicle!
       

       
      It has 5 months MOT and after fitting seat belts in the rear for the girls car seats it is pushed into daily service.
      My gamble and subsequent use results in a perfectly reliable car that actually does what it is supposed to do.
       
      Even more importantly Mrs T loves it so a win all round.
       
      All my cars have names (most are earned over a bit of time) and this one is called 'Gwendolen' ( G reg car and from Wales originally. I hate the name but I am not going to argue)
       
      That sums up part one, more will be along later (probably much later)

      Fackin oops.
       

       
      My goal was not to buy any more cars but with the Lanchester out of action while we work through it and make it safe to use, and the Princess out of action and needing the engine to be removed (a job I am procrastinating about, and when I'm motivated am thwarted by schedule and weather conflicts) it was getting more obvious that I needed some personal transport.  Something basic and reliable that I know my way around, that's going to be cheap to buy and run.  This is an ideal candidate, on paper.
      Whether I really can just use it as An Car or will end up getting all finicky about making it nice remains to be seen.  I just want some hasslefree pootling for a few months and normally Maestros are just that.
