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.

Cliff

1996 MAZDA MPV HEAT WONT GET HOT ENOUGH


You need to put a higher temperature thermostat in. Try a 200 degree thermostat and make sure that you have a full radiator. Also you could dilute your antifreeze a little more than 50/50 .
I would also try a 70/ 30 mix. Hope this helps.

Heater wont heat up


Check your engine running temperature. If not up to temp, then replace thermostat.
If getting up to temperature, then check operation of the heater matrix valve, cable/motor and switch assembly.

No heat in Ford Aerostar gage does not move. Heater core was flushed and new thermostat was put in


Just a guess, but I don't think you did this yourself. Take it back to the mechanic and complain.

You didn't say if this was the result of the flush and thermostat change or if you had the problem previously. I tend to think this is a thermostat problem still. It is possible the mechanic simply forgot to install the new thermostat (remote, but possible).

If you have no heat and the temperature guage is pegged cold, the engine is not reaching operating temperature. It is the thermostat's job to regulate this. Does the radiator get warm?

I would take it back to the mechanic if you trust him, or try another if you don't.

Replaced the radiator, heater core and thermostat and car still wont heat up...my car is a 94 mercury tracer stationwagon


Hi,

You've go so far but you havn't mentioned the water pump ! It's possibly 17 years old and due a rest. It's called a pump but it's mearly circulates the water provided the thermostat is open. It'll be a cheap fix compared to lifting the cyl head and head gasket replacement! You seem to have had some advice , replacing the difficult stuff (possibly from the supplier of a rad and heater matrix core??? ) If the car is running there is heat somewhere ! check the temprature of the Rad hoses , the will be hot (caution) after a few minutes of running. then check the two smaller hoses going thru the bulkhead (into heater matrix) and both sould be equally hot under normal conditions. If not .... pump replacement is a worthy option.

I have a 2006 dodge grand caravan, when the car is in driveway idling the car wont heat up but as soon as you start driving the car, the car heats up normally. Should i replace the thermostat or is it...


The reason for replacing the thermostat is improper cooling - not heating. The purpose of the thermostat is to shut off the flow of coolant through the engine allowing the temperature to build. When it reaches the temperature it wants the thermostat opens and allows coolant to flow to maintain the proper temp. Dodge Caravans have a track record for maintaining a low temperature until the engine is at higher rpm. While it is inconvenient in cold weather it it not bad. However, you want to check that your radiator fan is shutting off when it is cold. A fan that is staying on when it shouldn't could cause the temp to stay cooler.

Coolant doesn't heat up!

THE CAR DON'T GET TO THE RIGHT TEMPERATURE


i dont think it needs a waterpump. what temperature thermostat did you put in? unless the fan is running all the time maybe. i would try another thermostat, the engine needs to be at least 195 degrees to produce decent heat.
