Question about 1994 Ford Ranger Supercab
Has a new thermastat and new water pump
Mine does the same thing. One thing I did was to clean out the cooling system. I removed radiator connections and filled/dumped water into the block several times. The amount of sludge was unbelievable! I also removed my heater core and cleaned it out - it too was full of sludge. Problem is much better now but still varies while driving.

Does it ever get above 210 degrees F? If not, don't worry about it.
