Cold Heaters This Winter Problem

[jamesey]

my sharan is cold cold cold

i noticed it getting warm on a short run and when its free wheeling down hills the temp gauge goes back down to 0

ive bought a proper genuine thermostat and fitted it and it still does the same , it seems to take 10 miles to get hot up to 90 deg , the heaters are ok when it gets there , what can this be??

Hi Again

 

You obviously don’t much about cars or for that matter engines,

I will try and explain so that anyone who does not know how a

Internal combustion engine works.

 

First of all you have a combustion chamber which you squirt fuel

Into like Petrol, which is then fired with a spark, and this gets

Very hot, so you then have to cool it, what you do is make holes

All round the cylinders and fill with water, and this cools the cylinders

But as the Galaxy engine is so efficient, when you stop putting the engine

Under load, then the block cools off, and as if you then coast down a hill

Then the temp goes down.

 

This why they put a booster heater on the car to put more heat into the system

But if it is not working, then as long as the engine is still under load, the engine

Will keep hot, but remove the load and will cool off.

 

It just means the Galaxy, etc is a very efficient cooling engine.

Depends how far gone it is, if its semi working then it probably will make the sounds before shutting down (Flame out error) but if its fully broken the ecu will try 3 times to ignite it before disabling it alltogether (Open or Short Circuit) in which case it won't make any noises.

Jamesey,

 

You got a Mk1 or Mk2 ?

[TeamGreen]

One thing I would do is to make sure the fuel pump for the booster heater is ok as the terminals can corrode and break off. I went through the whole process of changing the glow plug, the original turned out to be fine but changed it any way, only to find that it still didn't work and it was then that I discovered that it was the pump was the problem.

Have you had the car from new? A previous owner might have pulled the fuse....

 

Not sure which fuse it is though as my Galaxy handbook makes up fuse locations as it goes. Number 12 seems to ring a bell though.

[edatelder]

And fuse no 8

[bofus]

even better than that, my Alhambra's previous owners actually removed the heater to save fuel AND looped the water hose back to the engine!

 

So a second hand heater from fleabay and a new aux water pump...toasty toasty....90 degs temp within 6 mins and 4 miles on even the coldest of mornings!
