It can a the first stage of blowing head gasket.

Fill your coolant tank to the full mark when it's COLD.

Start the car, and pay close attention to the tail pipe for a small puff of white smoke.

After 15 minutes,If you do see any vapor then take the car for a 8 minutes drive.

Park the car and listen for bubbling sound from the coolant tank,

If you see bubbles coming up then you will need a head gasket change real soon.

have you check to make sure the rad cooling fan is working and all the air has been purged from the cooling system, if so then the only thing left is a head gasket, cracked head, warped head. could be a block problem but this is unusual.

1. The thermostat in the cooling system could be sticking and need replacing. If it sticks in the closed position coolant cannot flow to and from the radiator and the coolant circulating through the engine will quickly overheat.

2. The water pump may be on its last legs and require replacing. If the pump has failed (and they do) the coolant will not circulate through the engine and radiator as it is designed to do and it will overheat quite quickly.

3. There could be a build up of debris in the cooling system that is impairing coolant flow through the engine. This can occur if the cooling system is not fully flushed out every 2 years and the coolant replaced. The cooling system must then be bled to remove all air. When replacing the coolant you MUST use the correct product as specified by the manufacturer and in the correct mix.

4. Radiator caps must be sound (and the correct specification) to ensure coolant does not escape and result in a low coolant condition and then overheating.

You need to get your car to a competent mechanic quickly to check and rectify the problem. (You may find it is only the thermostat as this is a common problem with time and usage.) Driving your car with an overheating condition WILL result in expensive engine damage. The head gaskets will blow and the heads on the engine will crack. Additional engine damage is also possible.

Cooling systems must be well maintained to prevent overheating and consequential engine damage.

First thing to check is the operation of your cooling fan, and coolant level

After that you should check the drive belt and tensioner, Thermostat and water pump.

You may also need to flush your cooling system

I've intrepid car has overheating problem has thermostat, working water pump, and keeps overheating

Might be blown head gasket. Is there oil in the coolant or coolant in the oil? Either of these would tell you that.
Also the exhust can get into the coolant and make the coolant low all the time.
I had two Chrysler products that the exhaust forced coolant out and had a bad head gasket.

when your engine is hot,check the temperature of your rad,if you get more than 30/50 degrees difference between the top and the bottom of the rad,you need to have your rad professionaly flushed.If you have a digital laser it will out perform any other temperature testing tool.

2002 pt cruiser overheating was told i need a new raditor and thermostat for 1 grand sounds fishy

Flush rad & change coolant & thermostat. Check operation of rad fan, & make sure it is coming on when engine reaches normal operating temperature. Be sure to bleed air out good when refilling rad/cooling system. Start engine & turn heater on when refilling & let rad fan come on & off at least 2 or 3 times before putting cap back on rad, and refill rad as needed as you do this. then fill return bottle to proper level & see what happens.

Ok, here is what I have found with the overheating problem with my 2002 PT Cruiser. I have got all the symptoms that everyone else has gotten form, it heats then cools down, gets hot when it idles, gets hot when AC is turned on. The bottom line here is that it gets hot when it is not going down the road or it may raise a little then go back to normal. This is what I have found after a new water pump, radiator, thermostat, cooling fan. What is happening is that the engine or radiator are starting to collect what I like to call calcium particles. so when the particles break loose they circulate around in the cooling system, when the radiator cap opens to let water out to the recory bottle these particles go out with it, however when the cap closes and tries to seal the radiator back up the particles get stuck under the seal therefor the radiator never pressurizes and continues to let water out filling up the recovery bottlle and then boiling over. I have proved this theory several times (and you can too) by letting the car cool down after a overheating tantrum and removing the radiator cap. Look at the rubber seal and i will bet you find these calcium particles built up on it not letting the cap reseal. I have cleaned the cap and put it back on and driven sometimes 2-3 days without a problem. The reason the temp will go up and down at times is because it deoends on whether or no the coolant has washed all the particles away when it opens and closes. Do a heavy duty and thorough cleaning of the cooling system making sure to get these particles out and you should be fine.
