Mar 28, 2010 - Temp gauge runs hot but car makes no heat. ... Honda-Tech Member ... I figured my theromstat was going bad so I replaced that and it did nothing. ... Any help would be awesome, im losing my patience fast and I have a real big hammer ... This is between the engine and the heater core (under the hood).
has the thermostat been changed lately? did the fluid leakage start about that time? check the thermostat housing and the heater hoses. i would also check that the correct gasket was used on the water pump. it is not unheard of to get the wrong gasket with the water pump. they may look right but a small difference can make all the difference. is it the correct water pump? are all the bolts on the water pump tightened properly?
If it's from the front of the engine, the water pump may have failed. Check for water coming out from the bottom of the pump. Was the overheating caused by low coolant level? If not the pump, check your engine freeze plugs and hoses.
you could have a expansion plug on the left side of the engine block leaking antifreeze,if your blazer is a 4x4 remove the skid plate under the front bumper and you should be able to see where its leaking from,a water pump will be a steady drip while its running usually but a expansion plug will pour out very fast
Yes it looks like it. Provided you installed the thermostat in the correct direction, Here's the test, remove the radiator cap, start the car and wait for the engine to warm up, When you can see the temp begin to rise on the gauge the thermostat will open. While reving the engine look for turbulance in the coolant/antifreeze in the radiator opening.
If none is observed then replace the water pump.
