hi to everyone..

i am attempting to replace the thermostat in my galaxy..i have looked at the dismantling procedure on the faq`s on the forum but it doesn`t show how to remove from car

i dont think there is any way of replacing the stat in situ unless you have hand like reed richards from the fantastic four

can anyone help with advise of how to remove the thermostat housing ??

i have had a look myself and managed to remove several layers of skin already trying to remove the hoses

help please :)

Hi there

These are the instructions from TIS manual

1. Disconnect radiator top hose,

2. Disconnect the lower hose

3. Remove the three multiplugs

4. Disconnect the remaining hose

5. Remove thermostat housing

6. Remove thermostat from housing

 

That makes it sound easy to remove, in reality probably not :)

thanks for the fast reply...your right the manual does make it sound easy

i`m still struggling to get the top hose off at the thermostat housing..i removed the battery..wondered if there is anything else i could remove to aid removal of the stat housing

I had mine off last week, its all a bit hard to get to, but if you remove battery, and all the plastic trim bits that seperate the battery and coolant bottle from from the engine then you should be able to get to water pipes more easily. Remove them and then you should be able to get to the thermostat housing.

The front 2 fixings are clear to see but there is another one round the back and recessed and therefore best tackled with a 5mm allen key bit on an extension bar.

thanks will remove that plastic round the battery and have another go at removing those hoses..i think the 3rd bolt is to the right hand side of the housing :)

got the hoses off but not sure of the 3 allen head bolts ?

i can see two to the left of the multiplugs

i dont suppose any one has got a diagram or photo so i dont brake anything else :)

Hi again

The photo's in the TIS manual are no help :(

Ok, looking at the housing there are the 3 electrical plugs, imediately above and below the right hand (brown) plug there are 2 long fixing bolts going through the thermostat housing into the engine. The 3rd bolt is shorter and right round the back, recessed to sort of be inline with the left hand (yellow) plug but on the oposite side of the housing to where the plug is.

If you get a mirror you can see it right at the back. As I mentioned before, you need an extension bar to get to it really. Obviously you also need to remove the 2 bolts that secure the housing to the rigid plastic coolant tube that runs across the front of the block.

 

Be warned that when you do get the housing off you should fit a new rubber gasket where it seals to the engine. I was unable to buy this gasket from GSF car parts without buying the entire housing, and so put the old one back with the help of a film of gasket sealant which apears to be watertight. I imagine you can get the gasket direct from the dealer but doubt it is a stock item. (Nothing else seems to be!)

 

Incidently I would be interested to know that upon inspection your old thermostat is complete. When I changed mine, part of the rubber seal on the thermostat (not the gasket but actually part of the thermostat) was missing and I later fished it out of the cooling system where it had been washed through and become trapped in the oil cooler.

I had an old thermostat from my old engine and that one was exactly the same with the rubber broken away and missing. very odd, anybody else out there noticed the same thing?
