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!

Rick

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.

Blessings,
