Having problems with your 2002 Chevrolet Blazer ?
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 plow and have no issues, the truck does have a clutch fan in it and we are now thinking that could be the issue....do u have any information on this problem from chevy?
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.
