At idle the water pump turns slowly as compared to when the engine is running at higher rpm. I believe the water pump has lost efficiency, probably due to corrosion of the impeller. If it were mine I'd change the water pump and quite possibly switch to a different type of coolant. Never ever use tap water in a radiator, Always use distilled water in the gallon jugs. They're about 99 cents each at the grocery store. Minerals in tap water calcify and clog the small passages whereas distilled has no minerals and doesn't.

SOURCE: PT Cruiser Brake Light

The bulb in the rear light has burned out and to replace it follow these instructions: 1) go to your owner's manual to find out the part number. You can find and purchase the replacement bulb at Target, any auto parts store and even at Walmart for under $4.00; 2) pop open the trunk door; 3) get a phillips screw driver and unscrew the 2 screws holding the rear brake light fixture to your car body; 4) as soon as you turn over the fixture you'll see where to pull out the burned out bulb and replace it with the new one(s). Good luck!

SOURCE: Change the thermostat on 2002 Chrysler PT Cruiser

Hi, i have put together a step by step guide that will help you with this replacement job. Make sure the vehicle is in a cool state before starting this job.


* Drain some coolant into a clean container until the coolant level is below the thermostat housing.
* Remove the upper radiator hose connection from the thermostat housing.
* Loosen the housing bolts and remove the housing.
* Remove the gasket and scrape it carefully from the surface of the housing and the mounting surface on the engine. If the gasket remains on either of the surfaces, there will probably bea coolant leak after reassembly. Some engines use a rubber O-ring to seal a thermostat housing.
* Compare the size of the thermostat to the old one. They are of different sizes, types, and temperature ratings.
* The temperature rating is stamped on the sensing bulb on the bottom of the thermostat. The temperature bulb faces the block.
* When replacing a thermostat, be sure that the thermostat fits into the groove in the block or outlet housing. If the thermostat is installed upside down, the engine will overheat.
* Install the gasket.
* Reinstall the thermostat housing. Refill the system and run the engine or pressure test to check for leaks.
* When the engine has reached operating temperature make sure the thermostat opens.
* You should be able to see coolant circulating within the radiator.
* Another way of checking thermostat operation is to feel the top of the radiator hose or use a thermometer or multimeter with a temperature probe to confirm that the coolant is warming up.
* If the engine is overheating, but the top hose is still cool to the touch, the thermostat is stuck closed and must be replaced.

NOTE
When a paper gasket is used and the recess is in the thermostat housing, it is a good practice to position the thermostat into the recess and glue the gasket to hold it in place. If it falls out of its groove during installation, the outlet housing can be cracked or a coolant leak will result. Before tightening the water outlet housing, try to rock it back and forth to be sure it is flush. Housings are often cracked during this step.

1st check fuse. Then see if power is coming to horn. A simple power checker can be found at most auto parts store. It may also have a horn relay. Look up your wiring at cargrus. If you still have problems contact me back.

Check your oil dipstick for coolant, or a mucky substance. Your symptoms sound like a blown head gasket.

Pt cruiser 2008 overheat i change the raditor and the fans , thermostat and still overheat lot of money and still


Has the system been flushed? Correct temperature thermostat installed? Are you getting flow through the radiator? Rad cap sealing properly and is it the correct one? Are the fans actually coming on? Is the temp sensor working properly? Rad properly filled or still have air trapped inside? Water level correct? Water pump working or seized, leaking?

Thermostat gauge goes about 3/4 way up after start up but when driving starts the gauge comes down about half-way and heat is good but at every stop, the gauge rises and heat cools again.....maybe stuck...


It sounds like there is a leak of some sort. (hose, freeze plug, water pump, blown head gasket, etc.) The coolant level is probably low. You need to check it ASAP! Check the coolant level and if it is low you need to find out why and get it repaired...You DON'T want to overheat that engine! Especially if you have the 3.0L V-6. It only has to overheat once to do some serious engine damage.

Removal of the thermostat from the cooling system is not a good idea. This upsets the coolant flow rate in the system, and that can cause the engine to overheat, even when no other problem with the cooling system exists.

Try to identify the cause of the overheating.

Ensure that engine tune, or other engine mechanical fault condition is not the cause of the overheating, then go through the checklist following:-

1) Check engine cooling fan/s are operating as required when engine temp rises above cut-in threshold - check fan control relay is ok,
2) Check for collapsing radiator hose on suction side of water-pump when motor revs raised above idle.
3) Check coolant reservoir pressure cap is serviceable,
4) Check coolant system is properly filled - carry out any bleed off procedure specified to clear any air locks- (ensure heater core coolant flow is turned on).
5) Check for combustion gas bubbles in the coolant reservoir while the motor is running - this indicates a blown head gasket. If in doubt, take it to a radiator shop and ask for a combustion gas check on your radiator.
6) Check condition of radiator core:-
i) for blockage of air flow to (bugs/grass etc),
ii) for core internal blockage to coolant flow,

If all above ok, replace the thermostat again (also ensure it is not installed upside down) - faulty new thermostats are not unheard of.
