Hey Guys,
Got a 1990 Ford Ranger in a trade. I decided that i'm going to chase every issue and rebuild this thing because its a cool little truck. First thing were chasing is no heat in the cab and the temp gauge is always dead on C on the gauge. The coolant was rusty water and disgusting. Yesterday we pulled the thermostat and ran 6 gallons of water through it till it was pretty clear. We replaced the radiator, upper rad hose and put a new 190 degree thermostat in it and actual coolant. The truck is working as it was before, lift tick louder than the exhaust, but nothing changed. Still no heat in the cab and the gauge still stays buried in cold.
Today I am going remove the heater core and try to clean it but the fact the gauge doesn't go up at all is confusing. I know the gauge is mildly working because when I am driving and I let off the gas or coast in OD the gauge will go up a little bit and drop back to dead cold. After driving for 5 minutes the upper rad hose is warm at best but not hot. Same with the radiator. We will take the gauge out and clean the rust off the reading side but how could the engine be staying under normal operating temperature. Anyone have any idea of whats going on??
Thanks!
