1994 Ford Explorer

Reader Question: HI,

I own a 1994 Ford Explorer with a 4.0 motor with 108,000 mi. The question is about the coolant temperature gage, which is erratic.

The car has been using coolant very slowly. I think the radiator is losing fluid from it. There is no dripping. I had a pressure test done and there were very little sign of seepage.

Is there a way to bleed the system? This just started to be a problem.

Thank You!


Hey Rick,

If you are constantly adding coolant to the radiator you really need to pin point and repair the leak FIRST. It could be something simple like a leaking radiator or heater hose or something more expensive like a radiator.

The temperature gauge could be erratic because of a bad Temperature Sending Unit, which is sending false data to the dash gauge. Or, the dash gauge could actually be telling you the truth and there is a cooling system problem.

Low coolant levels in the radiator due to a leak in the system, a faulty fan clutch, a stuck thermostat could all be possibilities.

I would repair the leak, if there really is one then see what happens.
