SOURCE: 95 CHEVY IMPALA SS RUNNIN HOT

You may want to try checking the fans. I have a 95 ss with the same problem. If you disconnect the MAF and then start the vehicle the electric fans will come on. Try driving it like that. That will atleast narrow down your search. If that makes it run cooler then its most likely a problem with the fans. Either a relay or fan switch. Blown head gaskets will usually result in the coolant and oil mixing. Check your fluids for signs of that. I have also read that the radiator cap not sealing properly can cause the coolant system to lose pressure. This reduces the systems ability to circulate the coolant causing it to run hotter. Thats an easy fix. I have not fixed mine yet. I just havent had time. That should be a good place to start. As far as getting a new engine or head gasket they are both really expensive fixes so try any other way u can to fix it first. Hope this helps.

You should probably replace the temperature sensor first, make sure the car is indeed overheating.

If after replacing the temp sensor, and the problem does exist, then buy a flush kit, and back flush the system, it may be clogged.

I would start by checking the fluid to make sure it's at the proper level, Then check to see if the thermostat is opening like it should. If you have good flow and you get heat inside the car but the car still overheats I think I'd be checking for blown head gaskets and head warp.

Overheating 2001 chevy impala


Believe it or not, new thermostats can be bad. Did you maybe get some adhesive on the thermostat preventing it to open fully? Is the thermostat installed with the crown up? The only other thing that I can think of, if it's a closed cooling system and the wrong radiator cap is installed, it won't hold the pressure, therefor overheating. The other thing may be the water pump. Many times the impellers will wear down internally causing to low of water flow.

My 2005 chevy impala keeps getting hot. It takes it a second to get warm but once it hits the half way mark, it goes all the way to the red and start beeping at me. I get the alert of high coolant temp....


You may have a head gasket or an intake manifold leak. Have the system (radiator) pressure tested to ascertain where the leak is located. Give the tail pipe the finger test. If you smell a burnt antifreese smell this is the problem. Good luck!

2004 Chevy Impala no heat from defrost or heater


No heat is often a symptom of low coolant, usually followed by overheat. There are other controls that regulate heater, but right now, re-fill the cooling system with engine running and heater on high, then check for leaks (coolant you lost went somewhere...you need to determine where) Low coolant will damage your engine. Take care of that first, then if heater still does not work, then do diagnosis on that. (if you loose the engine heat won't matter, will it!)
