With the truck running feel your top hose and bottom hose see if they are both the same temp. Actually your top hose should have pressure on it. If the hoses aren't the same temp you have a circulation problem. If they are check yourr fan clutch. See if its spinning fast enough.

If the engine top radiator hose is actually at HOT to the touch ( it will burn you ) and the coolant in radiator is full touch both heater hoses. One side should be HOT and other side warm. If that is all ok check fuses for heater and HVAC, both use same doors in hear control. I hope this helps you.Lee

Do you live in an extremely cold region? If so, those folks usually have a problem with heater in winter time. With a fully warmed up engine, how hot does it get in degrees F? Are the heater hoses hot?

You probably have a plugged heater core. If one hose is hot, and other one is quite a bit cooler or cooler, then you have a problem with flow through heater core. Try flushing it. I hope that will help.

Good Luck!

We have a 2002 chevy blazer, we just replaced the radiator, and leaking head gasket seals because when we try to drive the truck with our snow plow on it over heats.....we can drive it anywhere without the...


The problem is the plow. It is too much extra for your cooling system. You will need to put in a heavier 3 or 4 core rad to handle the extra weight and restricted air flow caused by the plow. You can also put in a colder thermostat for the winter. It will allow the rad to start doing it's job sooner. It's not likely that the clutch fan is the problem if you don't have overheating problems without the plow. If the truck is an automatic you should also seriously consider putting in a separate transmission oil cooler. Plowing puts serious straiand heat build up on the transmission and a separate oil cooler will save the life of it. Also increase the frequency of changing the trans fluid and filter. Keep the plow off the truck unless it is necessary, this will help a lot. Hope this helps.

2002 dodge 1500 Changed radiator, thermostat, and hoses. No heat


Why was radiator replaced?Did it have heat before ? If it was plugged, the heater core may also be plugged. Try flushing it with a water hose in both directions. I dont know why the botton radiator hose would be cold, the radiator should be a uniform temp and the air coming through the radiator should be HOT, when the engine is at operating temp. What condition was the old coolant? if it was rusty, the water pump may have lower flow than normal.
