89 ford bronco overheating

Sent to Car Experts July 15, 2006 11:42 a.m.

my 89 ford bronco is losing massive amounts of radiator coolant but we cant find any leaks. we've done all the obvious stuff--change the thermostat, flush the radiator, replace the temp sensor, pressure tests, fan clutch, hoses, run it with and without the thermostat, etc, but it still overheats. i'll either get water boiling up out of the overflow tank, or theres been twice when i checked the radiator and it was completely dry, when it had been filled and the car only driven maybe 15 miles prior to it being empty. any ideas where to look next?

Optional Information:
1989 Ford bronco 5.0

Thanks for the question.

Sounds like you might have a blown head gasket and or cracked head or block. NAPA has what is called block check. It is a liquid you pour into a testing device that changes from blue to yellow if a head gasket is blown. You may want to try this, that way you know what you are up against here.

Thanks
