Why is my dodge intrepid overheating

The only cap is on the overflow tank and the plastic is to thick to see any bubbles. There isn't any steam coming out of the tailpipe and there isn't any water in the crank case.

This car has been well maintained and I only use synthetic oil. I have taken the car to a mechanic to do a diagnostic on all the sensors etc, check the catalytic converter etc.

The cooling fan is working. That was the first thing I checked. I would not be on this forum if I had any idea what was going on. I have checked everything that would normally be a factor. Everything that has been suggested to me so far was checked before I posted to this forum. What other internal issues are you speaking of?

Re: 02 Dodge Intrepid is overheating Unread post by ProTech » Fri May 24, pm Well, something is making it overheat, and that's all the suggestions I can think of that usually cause a car to overheat.

Other internal issues could be burned valves, piston scoring, etc By the way, a head gasket could still be bad and NOT put any coolant in the oil or have steam coming out of the tailpipe. You'd really need to do a leakdown test to find out for sure, or at the very least a compression check although that's not percent accurate when looking for head issues.

If by turning the heat on full blast remedies the problem where the car won't stall, that's because you're taking away some of the heat from the cooling system. I'd still recommend looking for restrictions in the cooling system, such as build up in the hoses, passages, thermostat, etc.

Was it overheating before you had the new radiator put in, or just leaking? If it wasn't overheating until after the radiator job, something went amiss there, maybe the wrong radiator, or just poor installation.

If it was overheating prior to the radiator replacement, then still check my suggestions. That's about all I can offer, you've either got something extremely simple staring you in the face that you're missing, or you've got a problem child that's going to be hard to diagnose. And I don't know if the Temperature control valve would cause overheating if it was going bad. Am in need of some serious input as to what could be causing my car to overheat.

I am car literate, so I will understand what you say. Haven't been able to work for two weeks due to the car overheating, so if I get the answer that fixes the problem for my car, I will gladly donate then by submitting just a thank you note.

Right now I can't let go of any money. I should get points for being honest. Do you. Have the cooling system pressure checked for head gasket leak Was this answer. There isn't any water in the exhaust pipe. There isn't any water in the crank case. Cooling fans work. There are many stop-leak products that are only designed to be a temporary fix, but not ours.

The seal created from our product is as permanent as replacing the head gasket, but with less money and time. A head gasket sealer works when you pour it into the radiator. These sealants might not be the most permanent and could wear down over time. A real fix is to replace the head gasket, but this is costly. A head gasket sealer is a good temporary fix. Then he took it for a test drive and it overheated again. He checks the thermostat and finds that it has also failed; he replaces that also, still overheating.

New radiator hoses, upper and lower, new radiator, new thermostat, new water pump and it still overheats. He put dye into the coolant to check for a blown head gasket and it tested negative for a blown gasket. My mechanic friend and I both have run out of solutions and all of these repairs are draining my bank account. Any ideas? Also, a 12 year-old radiator could be clogged—you could feel it for hot and cold spots if you can get your hand in there.

These are good engines and not prone to many problems, unlike the 2. As stated earlier, all of the parts listed have been replaced. New radiator, upper and lower hoses, radiator cap, water pump, timing belt, thermostat, engine and heater core and hoses have been flushed twice. The entire system has been bled a dozen times.

It has been dye tested for combustion gasses twice. It stays at a normal temperature while sitting in one place and the cooling fans turn off and on like they are supposed to.
