I dont think it needs a waterpump. what temperature thermostat did you put in? unless the fan is running all the time maybe. i would try another thermostat, the engine needs to be at least 195 degrees to produce decent heat.

Cannot change temperature on heat & air


Temp is controlled by an electric motor(or could be vacuum hose) on the blender door of heater housing. If you find this is operating correctly, then the problem is a plugged heater core.Backflush it by removing both heater hoses and flushing from water pump side toward thermostat side.don-ohio

I have a 2002 mitsubishi montero sport and we changed the thermostat, did a radiator flush and change radiator cap and the needle passes to mid point (normal) it hasnt overheated but it doesnt stay in...


Where do you live?
This has been a hot summer, bit hotter than usual due to the solar flares going on...
as long as the pointer stays within normal operating range, you must not worry... especially since you changed the thermostat and did a flush, did you make sure you got the right temperature range thermostat installed, rarely but few times that seems to be the problem, hotter thermostat gets installed by mistake.

What is the normal operating temperature for a 2003 Chevrolet Impala with 3.4L engine? Mine use to be around 185 to 190 degrees on the gauge inside the vehicle. The gauge now can range from 200 to 220...


The range should be in the temp range of your thermostat within in a few degrees, you probably have a 190 degree thermostat. As the outside (ambient) temp rises it's normal for the engine to run a little hotter 200 degrees is safe with coolant, water boils at 212. Your fans should cycle, so it sounds like your temp sensor is faulty. if you haven't flushed your radiator and changed your thermostat lately, now would be a good time to do so. Hope this helps,

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.

Temp gauge is in normal, 200 degree, range when starting. Within a few minutes of driving goes up to 250, right below orange line. No leaks found, coolant level appears fine. Any ideas?


250 DEGREES ENGINE GETTING TOO HOT.SOUND LIKE CLUTCH FAN FREEWHEEL.IF CLUTCH FAN DONT LOCK IN OR HAVE RESISTANCE TURNING BY HAND WHEN ENGINE HOT.FAN CLUTCH IS BAD.IF FAN CLUTCH OKAY COOLANT LEVEL CORRECT.I WOULD CHANGE THERMOSTAT FLUSH OUT ENGINE AND RADIATOR.IF ENGINE TEMPERATURE STILL READS 250 DEGREES OVER FLOW JUG OR RESERVOIR NOT BOILING OVER THE COOLANT TEMPERATURE SENSOR FAULTY.

Changed thermostat and flushed heater core heat is warm, not hot.. and temp. gauge works sitting still but goes down back to 0 when driving


SOUND LIKE PROBLEMS IN THE AIR TEMPERATURE CONTROL DOOR NOT OPENING.CLIMATE CONTROL VECHICLE HAS TO BE HOOKED TO DIAGNOSTIC EQUIPMENT TO CHECK.IF YOU REPLACED THERMOSTAT.FLUSHED HEATER CORE AND RADIATOR.YOU HAVE THE RIGHT AMOUNT COOLANT IN THE COOLANT SYSTEM.LET DEALERSHIP CHECK IT OUT.

I just had a new radiator and thermostat put on my 1996 Nissan Altima. The temps here in SoCal are in 90's. My temp gauge keeps going up past the 1/2 mark. What is happening? I can't afford to break down...


If the shop installed a different thermostat (there are different actuation temperatures), the normal position of your gage will change accordingly. As long as it's still in the normal range and stays at a new "normal" level, I'd say you're OK. If it is getting too close to the red, ask them to reinstall a lower temp thermostat.
