If it is coming into the vehicle it could be a leaky hearer core. If it is the outside of the vehicle you should inspect all the hoses and hose clamps as well as the reservoir cap.

The turbo is cooled by the cooling system as well, carefully inspect the area around the turbo for leaks.

What is wrong the temp does not get hot going down rasd


I would buy a new thermostat and flush the radiator coolant. Dexcool (The orange coolant) is known to clog up the internals including the temperature sensor in cars of your age.

While you are at it, I would strongly consider changing radiator hoses and clamps unless that was done recently.

If you are referring to the dashboard temperature gauge not moving...It means that your temperature sending unit may be faulty (or it's not plugged in). Dexcool is known to clog up the internals including the temperature sensor in cars of your age. Inspect the connector to the temp gauge for damage and replace the temp gauge.
A replacement temp sensor is about $15 at any auto parts store.

Good luck

2004 Impala ls temperature dash gauge


fans came late on those car,like 212 and second fan comes on at 224,you reprogram it to come a lot sooner,,other thing is there might be gunk inside the block,and coolant has hard time to pass through,and staying longer than enough in block temp goes high,even tough the radiator is doing it's job,it is just coming out block lot hotter than it suppose to be,and gauge read the block not the radiator

2002 dodge neon running VERY HOT ... what to do next?


Have you verified that system has been "burped" of air? That the fans kick on? Check radiator hoses for kinks. You can try running without the thermostat to see if that helps and can identify if the thermostat could be a problem. You may need to check your coolant mixture too.
Sounds like you have reduced flow or restriction in cooling (heat exchanger) as it runs fine at cooler temp but can't keep up when it gets warm.
New parts don't always equal working fine parts.

My 2004 sentra is overheating the thermostat has been replaced the spark plugs have been replaced and i have flushed the radiator with no avail. my water pump is not leaking and seems to be running fine....


You need to check the fan on the radiator. Also check the nozzles for the input and output from the radiator. If the nozzle at the radiator inlet is not hot, then the problem is in the cooling system. If the nozzle from the radiator is hot, then the problem is in the radiator. Be careful not to burn yourself.

My 06 Grand Prix was getting hot, not overheating, but getting hot. The O2 sensor was replaced just prior to the problem, the radiator was flushed, the Thermostat was replaced, then the water pump blew...


You should make sure there is no air in the cooling system-from a cold start, let it idle until the radiator fan kicks on with the surge tank cap off-make sure the tank is fully up to level at this point, that should eliminate air in the system as a cause. If you do not have a scanner that gives live readings, get one so you can monitor the engine temp-a factory gauge is not overly accurate. Your temp when warmed up, air off should go to about 212-215 and the radiator fan should then kick on-temp should drop to about 200 and the fan should shut off-this is normal.

There are two coolant temp sensors. One by the oil filler tube and one near the bottom radiator hose near the radiator.
When you flushed the coolant did you replace with VW rated G12 coloant? Very Important! - You can't use over the counter coolant - it'll cause sludge in your system. You have to use G12...

Hope this helps!

1994 Chevy Silverado temperature guage shows hot


Flushing the radiator, replacing the radiator cap, adding new coolant, replacing the sensors and a new thermostat solved the problem. Probably didn't need to do all of these things - but since we just purchased the truck, and given the fact that is probably hadn't been done in a while, we chose to do all of these things (which really didn't cost a whole lot), it's running like a charm now.
