Low coolant?Bad thermostat?water pump?system airbound?hoses collapsing?defective radiator cap?cooling fan if so equipped?
Low coolant? Radiator probably needs flushing and/or replacing after 40 years. Bad thermostat? System airbound? Water pump not circulating coolant? Hoses collapsing? Bad radiator cap?
Your truck is overheating because it needs a new radiator. I had the same problem, after I installed the new radiator and flushed out my remaining cooling system I never had a overheating problem since.
my 1991 b2200was overheating until i removed the radiator and sent it to be cleaned, problem solved.
With a release tool.
It may be inside your radiator itself.
Replace with reinforced hoses Check radiator cap for proper pressure
No.
Low on coolant, radiator fan inoperative, thermostat failed, water pump failed, radiator plugged
If your truck is overheating!!! Then check the upper radiator and lower radiator hose's , if the lower is cooler the the upper the either the thermostat is not opening or the radiator is clogged
It is between the battery and upper radiator hose where it comes out of the radiator.
Look at the bottom or rear of radiator
