GM and GMC

Why does your 1986 GMC pickup overheat with coolant boiling back into the reservoir when it pulls any size load up hills?

There many other reasons for a vehicle to overheat besides thermostat and radiator cap. one example is retarded ignition timing.

where do i put coolant in for 1994 Chevy s10 pickup

no it doesnt........the overflow container is just there to catch the extra has nothing to do with the heating system

If it still has the original DexCool coolant, it would be a pinkish/red.

It is located on the bottom of the windshield washer reservoir.

Low coolant? Thermostat not opening? Radiator plugged? Radiator air flow restricted? Hoses collapsing? System airbound? Water pump not working (defective impellor)? Bad radiator cap?

It is located at the base of the windshield washer fluid reservoir.

where is the coolant sensor on a 1984 s10 blazer 2.8 6 cylender

Replace the engine coolant sensor.

The green color antifreeze will be just fine.

There isn't a transmission fluid reservoir on an 86 S10 pickup. The transmission fluid is held in the transmission itself.

The first step in removing the window washer fluid reservoir in a Dodge Ram 1500 pickup truck is draining the radiator. Next you will remove the upper hose for better access to the reservoir. Detach the hose and remove the wire harness surrounding the reservoir. Lastly, release the mounting tabs and pull upward on the reservoir.

There are a number of reasons: 1. Faulty thermostat can cause the fluid to overheat and expand; thus causing the fluid to vent from the overflow pipe. 2. A punctured radiator hose, or a broken seal can cause loss of fluid. 3. Damaged radiator core.

If the master cylinder reservoir is empty, you have a leak somewhere. If the master cylinder reservoir is full, the master cylinder is bad.

below the raditor hose that's connected to the thermostat.

Yes, but only if they are both the same configuration, i.e. both 4 cylinder or both V6

The 1992 Ford F2 50 pickup truck 5.8 liter engine coolant temperature sensor can be found on the top of the engine. The coolant temperature sensor will be near the intake manifold.

check the coolant level first, low coolant will cause no heat, always check all fuses just in case

If it is stuck closed, the engine will overheat. If it is stuck open, the engine will take a long time to reach operating temp.

i asked this question the tempture gage shows it is over heating but the engine is cold to touch

Low coolant, bad thermostat, clogged radiator, bad waterpump, bad headgasket, etc

replace the coolant sensor, the one next to the thermostat housing.

its in one of the lower corners of the radiator. usually on the back side.
