Question about 2002 Chrysler Voyager
The temperature wont lift and theres no heat in the car, i think its the thermostat, i have one of a supplier for 80pounds they said they are so expensive because they come in a sealed unit, does it have to come direct from a chrysler dealer? My mechanic has never worked on these cars before have you anyone any advise on how to fit it
Hi there, this post if for everyone who wants to change the sealed thermostat on a Chrysler Grand voyager.
Firstly purchase a new unit from a dealer, mine cost me £115 plus vat and you will also need a gaskit for when you fit the new stat. I would also have a magnetic telescopic stick handy, buy one from halfords because you will need it trust me!! This is for when you drop the 10mm bolts down the engine and you will need to recover them. Very handy tool indeed
secondly you will need to drain the cooling system, you can partially drain off by disconnecting the top metal hose unions on the right hand side of the engine near the reservoir
Thirdly you will need to remove the bulkhead(wiper motor housing and wipers) at the base of the windscreen. You will now see the thermostat housing which is tucked away at the back of the engine and with the hoses attached. I have to say this is a dificult job and is hard to get at unless you remove the plastic bulkhead as described above.
Fourthy you will need to remove the hoses and jubilee clips carefully taking care not to split any of the large and small hoses.
Lastly there is a small nut holding the turbo hose and the diesel pipes to the housing, a small 10mm spanner and a lot of patience is required to remove this nut, then release the 3, 10mm bolts holding the thermostat to the cylinder head.
After cleaning ALL the old gaskit from the mating surface, check using a mirror then smear a little red hermetite onto the stat housing and cylinder head mating surface, fit the gaskit and then tighten the bolts up to 28nm aprox, you will know how tight to go without stripping the thread, you won`t be able to use a torque wrench because of innaccessibility Then in reverse order replace everything as described above as for removal.
Hope this helps, You will now have a car with a fully working heater and will also improve the mpg because the engine will reach optimum operating temperature rather quickly even in sub zero temperatures outside of the car.
Any further questions please post and I`ll try to answer them.
