The Epic Austrian owned R16 from Germany doing French things in a Parallel Universe near England Saga

The glas fills up when the cooling system is not 100% air and water tight.

Leak can be anywhere, quite often top seal of the glas or overpressure valve in glas cover kaputt and opens to early.

 

Normal operation:

- Engine heats, water expands, overflows into glas, air on top of glas builds pressure.

- Engine cools, air on top of glas pushes water back into system. All fine.

 

System not sealed:

Engine heats, water expands, overflows into glas, air on top escapes, no pressure.

Engine cools, no pressure, water stays in bottle, problem.

 

find the leak....

 

By the way, glas should be filled to about 1/3d on cool engine, no more.

 

PS

If for any reason you feel need to open the hot radiator, always take out the glas and pour all the water into the radiatior. System will then settle itself with no need to bleed the system.

all above valid for 504 and Tagora, Renault built with  stolen Peugeot technology  presumably the same.

I know. Bleeding procedure of R16 explicitly states this. It says 3 cm above max mark, which is approx 1/3rd full if you are an optimist, or 1/3rd empty if you are an optimist with experience.

Will not work on R16. Heather matrix too far above radiator level, thus will never self bleed.

Renault not stolen technology. Renault pioneered. Sadly. Because daft.

 

They later replaced the glass jar with a plastic expansion bottle having the hose from/to the radiator mounted at the bottom of it and a nylon one way valve for the air at the top. So they realised that their initial setup was a bit shit. However, upgrading the system now is not an option, because having a family sized Amora Croq’vert Extra Fins glass filled with a vile looking liquid is just too arrestingly beautiful.

Fuck me, a replacement valve costs 70 Euros! Only available from the R16 shop in Holland.

 

The valve indeed failed initial fellatio tests, but then gradually started to work. It has thusly been decided to boil it in a 50 water 50 non brewed condiment mix for an hour or two.

I rather rack up a 70 quid electricity bill than sending the dosh to a greedy man who wears clogs when he rides his beige tyred pushbike from his tulip field to his windmill while smoking a spliff.

Did you have the exact same symptom?

How would the system behave if the expansion bottle seal or valve were at fault?

I had problems with the expansion bottle filling and not emptying.

On another occasion the cap of the expansion bottle was split but that resulted in coolant all over the engine.

 

I've never owned a Renault though.

I boiled the valve and the actual radiator cap with a dishwasher tablet for two hours. This is what they look like now.

The rubber seal of the radiator cap has that wear mark all round, so I inserted it upside down.

Reinstalled everything, filled the expansion glass to what it says in the book.

Bled the system exactly like it says in the book, system bled, heather got toasty warm, fan came on, went off, came on again.

Good.

 

 

Level in expansion bottle remained unchanged by bleeding procedure.

Now it's all about waiting what happens when everything cools down.

Strictly speaking in ICE terms, would it be correct to say that this engine has cooled down?

Mind you, it was at fan engaging temparature two hours ago.

 

Well, the content of the expansion bottle has lowered itself to the full mark level.

I don't want to sound too optimistic just yet, but the chances that I don't have to infest my Renault with Simca bits are increasing.

The good news is that the car now households with its water exactly like the old Renault advertisements promised.

The further good news is that it now runs right once again.

The bad news is that that Weber is essentially knackered too and the exhaust makes quite a racket yet again.

I don't want to fix it unless the carby/fannymould swappage ensues at the same time, otherwise I have to do it again.

I think that he's still alive and is on the Darkwob, along with a few other ex forum members.

No, I'm sure I read he's gone AWOL.

Junkman hasn't died! Just taken a break from the internet. 

I wonder if he 's chopped in the 16 for a financed-up new diesel Megane?

Junkman still has the 16. MPG figures are in the mid-high thirties and it is running well with a new carburettor - in September it took us on a week long roadtrip through France of about 2000km.

 

It isn't being used much at the moment due to the season.
There's no chance you'll ever see Junkman on these pages again, or possibly even the Dark Wob: he's just a bit sick of fora in general.
