Can somebody tell me if the overheat in mallard chevy sprinter motorehome 1986 can be caused by changing drive rite alt fan & idle belt and drive rite v belt, before the overheating?

Your post is not clear to me but if you are saying you did some kind belt conversion, that caused it to start overheating, check to make sure the fan is turning the right way.

a 1986 chevy chassis...I would guess a 350 engine...does it overheat going down the road...or ....stopped in heavy traffic....two things come to mind on that old of a motorhome...is the fan clutch and the radiator is either clogged internal or external or both...

make sure there the radiator is not full of leaves or dirt between a.c. condenser and radiator...if internal..it is cheaper to get a new radiator ...usually...

"If" there is a 454 engine in there the same holds true...but make sure you get the correct size radiator...cheap is not always the best way to go especially radiators....good luck

If you put a serpentine belt conversion on there..your water pump is turning backwards and you will have to replace with the correct pump and fan for sure....

anytime you update something....it will affect something else...
