HMC- Pondering over a rover 75 matter

[Heidel_Kakao]

If it still thinks a door is open I believe it will leave the interior lights on and that includes the light inside the spare wheel well so that could well drain a battery.

Take the rubber cover off the alarm sensor on the nearside.of the slam panel. After all the bad weather I'll bet it's full of water and shorting out. No idea how it gets in there but it does!

If the car thinks a doors open it won't lock and the alarm will beep loudly once. As said above, the interior lights will stay on. Just manually switch them to stay off until you can sort it.

Good choice on the diesel auto as well. As long as its not rusty and/or falling to bits then you really can't go wrong with that. Tourer has superb load space too, a proper estate car.

Worth checking the glove box light is not sticking on if it has one. Ditto illuminated vanity mirror if it has them.

Mine occasionally beeps, but still locks, if the tailgate isn't 100% closed - just something slightly in the way. I've aways sorted it straight away so no idea on battery drain though.

Is that the slam panel for the bonnet?

Yes sorry that's the one.

Agreed- its so 50s - usually the brochure artwork shows the ambition, and the reality is a bit different! 

Daimler seem to have been particularly guilty of this it seems…..

Shameless!

[HMC]

But I do like how “dignity “ is cited as a sales feature. Very different times 😂

[adw1977]

Different times indeed, when a man had very different suits (and hats) for town and country.

[lesapandre]

People wore a hat in the car - and driving gloves. That's why they had 'headroom'.

[barefoot]

I still do.

[DSdriver]

Automatic chassis lubrication:  something certain Citroens are rather good at 🤣

I had great success earlier, in the midst of a cold snap, in freeing off carefully and successfully, the heater  valve on the daimler. 

Ive now got very  slight wisps of tepid air coming through. Maybe the matrix is clogged? Any recommendations on how to improve the performance?

[somewhatfoolish]

If it is wisps I'd look at the air flow path of the heater; is there a filter or wire mesh that's encrusted with 70 years of grot obstructing the flow? Is there grot in the matrix? Is the fan motor putting all of its dobbins out in synchronisation? Are all the phlappy phlaps phlapping as intended?

The nuclear option is to put a couple of dishwasher tablets or dishwasher cleaner in the radiator and take it for a  long run. 

Then drain the coolant out - it will have a drain plug on the rad and probably one on the block the heater may have one too.

Then disconnect the heater in and out under the bonnet and connect a hose to the in - and extend the out with some plastic pipe so it drains away from the car.

Gradually increase the water pressure and let it run through for 10 mins.

At the end you will either get it back together and find:

Nothing has changed.

You have the flu.

It leaks everywhere.

You have heat.

Daimler and Lanchester owners club may have a spare matrix - who knows.

I'd give the block a flush through too.

The only true answer is to swap it for a newer Daimler😉🤣 

 

On a more serious note I’d be pretty surprised if it was a particularly good heater even when it was new to be honest, I’ve never had much more than a “mildly warm mist” from any 50s car heaters

Re the Rover 75 door closing issue - it could also be the microswitch in one of the door lock mechanisms that has got stuck - that can happen in cold weather, mine did it a few years back.

[lesapandre]

The heater box - ie the heat exchanger may be a generic one from the 50's ie a 'Smiths Industries' or some such so there may be a replacement about to fit for when the original gets recored. 

Try muffing the radiator grille - the car may be running cool. What does temp gauge say...or is it accurate...

Silver foil should do it.
