the v6 2.9 litre Ford motors cam,e with aluminum heads and after a few years of wear and tear and constant heat they tend to expand and contract until the warp or crack and no longer seal well causing them to leak or blow the motor.

How do you change the thermostat on 1989 ford Bronco Eddie Bauer full size?

The top radiator hose feeds into a round metal thing on top of the engine. Drain the radiator, take off the top hose by removing the hose clamps, inspect the hose for damage and cracks, the round metal thing (thermostat housing) can be taken off by removing the two bolts that hold it in. take out the old thermostat and replace it with the new one. It may have a rubber gasket so double check. Put it all back together and refill the radiator with 50/50 antifreeze and water. Run it til the level drops and top it off again. Check for leaks.


After changing out the radiator cap thermostat radiator hoses and cleaning the cooling system what could be the reason for a Ford bronco II to overheat?

Remove trapped air from the systemI had the same problem on my 1988 2.9L Bronco II. It seems that there was air in the cooling system somewhere! I paid a fellow in Chattanooga, TN $48 to bleed the system and the problem was resolved. That was three months ago and the fix has stuck. His solution also allowed the heater to generate hot air again, which was a good thing as it gets downright chilly here in eastern Tennessee during the winter. How air gets trapped in the system is beyond me, but there you are. Hope this helps.i think how you get air bubbles in your radiator is putting the fluid in too fast. if you poor it in slow that should fix the problem if it is just air bubbles.could be something as easy as retiming your trucki had this happen to me on a 85 bronco you have to burp the system by raising the front up as high as you can or if you put the flush and fill kit on the heater hose you can put the coolant in there and that solved the problem for me

I have a 1990 ford bronco II-4x4 trans with two coolant fittings on it one on top and one on bottom. which one will connect to the top radiator fitting and which one connects to the bottom fitting?

It doesn't really matter which is connected where,but I would connect the suction side to the lower connection on the radiator. roll the motor over a little and see which line is spitting out fluid and then connect that one to the upper side.

You may need a universal joint if you are unable to get a socket straight on it due to the belts/fan.
