    It sounds as though you don't know or work on your own vehicle. So I would go to a shop and have all your issues repaired in one sweep

    Your right im a girl know nothing about vehicles lol but im learning more and more with this one. OK bought the car had it two weeks started having problems. I took it back to the car lot and they took it to a mechanic. He said he checked everything thermostat, radiator fans, and to see if it had a cracked head. He said it just needed a thermostat. It still overheats After i got it back it began to get to where it didnt wanna start. You can hear the starter trying to start the engine but the engine doesnt turn over. And this ONLY happens on occasion 3 to 4 times a week. I know it cant be the starter otherwise it would not start at all. Thinkin maybe the fuel pump but again not sure new at this. The third issue is that the car does this thing to where it wont go a certain speed. For example i was going 75 on highway all of a sudden it dropped to 30mph and no matter how much pressure applied to the pedal. Feels to me like an air bubble or that it kinda chugs or pulls back like a go kart out of gas but with a full tank.

It sounds like a blown gasket on the intake manifold.
You see the over heating was the real problem and that was caused by the radiator and heater core being clogged Chevy has this problem.Then the intake manifold warps and starts sucking air in .This fools the computer and you have all kinds of other problems with performance .

It is probably the problem. To make shure that need to change the gaskets, one of the symptoms use to be thet the temp rises when you are running at speed 50+ average, where is supposed that the car gets a lot of air due by the speed and nobody thinks that will be overheated.

SOURCE: replaced cracked radiator in 2000 Chrysler LHS but car still overheating. What could be the problem?

I had the same problem. My Chrysler LHS kept overheating. I had the thermostat changed out first and it didn't help. Then I had the water pump changed out and still did no good. Then changed out the radiator, still overheated. Come to find out the people that changed my thermostat put it in backwards. Evidently, the thermostats for these cars look different from all the others and people are not sure how to put them in. I took mine to a Chrysler dealer and they fixed it for me.

2002 pontiac aztect overheating has new thermostat and water pump


Try removing the thermostat and reverse flushing the motor, Actually try flushing in both directions, this will tell you if you have a circulation problem but 1 thing you should know is that the water goes in the water pump and out the thermostat, try running it without the thermostat and check your water flow

2005 Nissan Sentra overheating. Changed the water pump. Did a radiator flush. What else could it be??


Some thing too check:
Make sure coolant level is up to line and clean (not dirty, do to clogged radiator, may need to be flushed or replaced).
Make sure air flow through the out side of radiator is clear (dirt, leaves, ect..) .
Make sure fan is working properly equip t (is not running too slow). Or Manual (belt driven) fan clutch is working properly, not loose or spinning too freely?
Check for broken or cracked fan blades itself.
Check radiator cap, (no gasket tears).
Could be thermostat going bad ?
Could be coolant temperature sensor/switch (from computer) going bad?
Check radiator hose(s) (too soft, may collapse)?
In some rare cases:
Timing could be off.
Could be water pump.
Could be blown head gasket(s).
Could have cracked head(s).
ECT..............Hope this was some help???

Keeps overheating after i have already changed water pump, thermostat, an having radiator flush an new heater lines


Make sure the radiator fan cycles when vehicle reaches about 220 degrees, if not replace the electric radiator fan and relay. The fan relay sits below the passenger headlamp. If that is working correctly you may have a cracked or warped cylinder head. Most shops can do a chemical test to the coolant system to check for combustion chamber gasses from cracked heads, the only drawback is that this test only tests for combustion gasses and doesnt usually show when the head has cracks between coolant passages

Car overheating. taken thermostat out and it fine. not sure if radiator blocked or not whats best way to clean and repair cooling system at home i have different things like stop leak (used once already)...


Not sure if I am understanding you correctly or not but if you took the thermostat out and your no longer overheating all you need to do is replace the thermostat. If you are still overheating it can be a number of different things, a blockage, cracked head, bad hose, ect.... Stop leak can causes build up in the system because it is made to clog leaks. You may need to have the system flushed by a repair shop. But the thermostat seems to be your issue.

First check that the thermostat was installed correctly. It will not work properly if it was installed upside down. If this is the original radiator, it most likely is plugged up with deposits and corrosion. It needs to be replaced with a new one.

Dodge 2002 Grand Caravan V6 3.3 engine overheating/no cabin heat.


Replace the bad radiator hose first.  Second- get you special formulated anti-freeze dye from the auto store and pour it into the radiator.  Third- make sure you got all the air pockets out of your system, cause the coolant system won't work with air pockets in it.  Fourth- Check for leaks by looking for the colored dye.  If it's not the radiator hose, then could possibly be a pin hole in your radiator.  Would suggest replacing all the radiator hoses at the same time while you got the coolant system disconnected, cause you don't want to have to come back and replace another hose in a few months.

My 02 Grand am V6 keeps blowing up all my water hoeses. it even cracked my radiator. it doesnt over heat until it brakes a hoes.


you got a restriction in engine block.its full of rust.flush block out by taking the thermostat out.remove the top hose to thermostat then move lower hose to water pump .place a container so the lower hose can catch the water as you flush out block with water hose.flush from the top where thermostat goes flush until you get a good stream of water from bottom is clear.before you start this procedure drain out antifreeze first. flush out over flow jug make sure its not stop up. and change the radiator pressure cap.

Jeep Overheating?


I would suggest you have the radiator and cooling system pressure tested . .another option would be to get a new radiator cap and try that. If you want to do a quick test for the radiator cap .. try loosening it to the first notch and see if your overheating problem subsides ..
