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.
Follow the top radiator hose from the radiator , where it connects to the engine is where the engine thermostat is located
Drain coolant. Remove upper radiator hose. unbolt 3 bolts on thermostat housing. take out old one. reverse to install.
Should be located in a removable housing at the engine end of the upper radiator hose Drain about 1 gallon of coolant from the radiator Remove this housing Note how thermostat is installed Clean both surfaces Replace thermostat and gasket Re-install housing Re-fill coolant slowly to prevent an air lock Start engine and look for leaks Run engine to normal operating temperature with heater on Re-check coolant level
possible clogged radiator or thermostat not opening all the way hope this helps
how to replace a thermostat on a bronco 198511
The thermostat is located in the water neck where the top radiator hose goes on. Its mounted in an O-ring, just pop it out with a screwdriver and replace it.
fill up the radiator and then fill up the over flow located on the pass. side of the truck half way
check your thermostat
WHERE THE UPPER RADIATOR HOSE CONNECTS 2 THE ENGINE THERE IS AN OUTLET(GOOSEHECK) UNBOLT THAT & THE THERMOSTAT SHOULD BE THERE & BE SURE 2 INSTALL THE NEW ONE CORRECTLY BECAUSE A BACKWARD THERMO WILL DESTROY AN ENGINE.
With the engine warmed up so the thermostat is open , squeeze the top radiator hose and then release it , as you are releasing it you should feel a surge of coolant going through the hose if the water pump is working ( carefull - watch the moving belts , fan etc - its nice to have fingers )
drain the coolant, remove the two plastic intake tubes from the throttle body an air cleaner box an then remove the top radiator hose then remove the thermostat housing(2 bolts) remove the thermostat an clean the housing both parts (where the two parts of the housing meet) make sure u get the old gasket off an both surfaces are clean an dry an then reassemble with new gasket an thermostat (the spring side goes in towards the block) put the hose back on ( this would be the time to replace the hose clamps there cheap) then put the two intake hoses back on the TB an the air cleaner box an the fill radiator. : )
A water pump is not really a water pump. It carries the fluid, antifreeze/coolant, from the the reservoir to the radiator/engine to keep it cool. It is now referred to as a "fluid pump"
( 192 ) degrees Fahrenheit for all the factory available engines in a 1991 Ford Bronco ( according to fordparts.com )
Ford doesnt have a 5.7l. On a 5.8 it is behind the thermostat housing at the front edge of the lower intake.
depending on what year and what engine you will need to remove the fan and fan shroud the lower radiator hose the coolant bypass hose and in some cases the power steerig bracket. not that hard to do if you have some car knowledge
A 1996 Ford Bronco came from the factory with a 50 / 50 mix of distilled water and GREEN color antifreeze ( meeting Ford specification ESE-M97B44-A ) in the engine cooling system * THAT includes the radiator
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.
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
on the left side of the automatic transmission, where the shift lever attaches. "D" shaped, with 2 wires.
Under the radiator overflow and washer fluid reservoirs.
If I remember correctly the 351 Windsor has a vertically mounted thermostat that is mounted in the end of the intake manifold The 351 Cleveland thermostat is mounted horizontally in the engine block by the distributor
Sounds like you have a bad coolant temperature sensor. Its the sensor on the passenger side of the lower intake manifold by the thermostat. You may want to check your antifreeze level if mine gets to low it does the same thing
I'm not sure what you mean by direction? The thermostat goes in with the spring side in the housing with the metal cross bar horizontally positioned.
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.
