94 Ford Ranger Overheating Question
I work at an automotive repair shop and the techs there cannot fiqure out why my 94 Ford Ranger continues to overheat after the head gasket has been replaced. My entire cooling system is new. When I drive home, about 15 miles, some stop and go traffic and then speeds up to 65 on the highway, the tempertature has reached H on the gauge by the time I reach my destination. The tech who did the head gasket job claims he let it run for 3 hours and it never got hot. However, idling the vehicle for 3 hours does not replicate normal driving conditions.
There was mention that perhaps the water pump was ordered from Worldpac rather than Napa - and the part was purchased to replace a water pump for a Mazda truck rather than a Ford truck - which has a reverse water pump. The heater does not blow hot air. Basically, the syptoms are exactly the same as before the head gasket was replaced. Overheating, no hot air out of the heater. Any suggestions would be greatly appreciated!
