Hi all,
Need a confirmation before I pull the trigger on HG job.
Condition: 96 FJ80 with 177K. Recently flush the coolant and refilled it with Toyota Red. Saw some grey sludge, but it seems that everyone has it too and I never had any overheating issue prior to the flush. I also replaced the belts (fan belt and condensor) just because I never replaced them before.
I drove it for a week and today the temp went up to 3/4 and lost my heat air to the cabin.
Did some reading and found a few suspect to check: Radiator cap, fan clutch, thermostat, or Head Gasket.
So when I pulled over and stop, the overflow tank.... well overflow and boiling.
After it cooled down, the radiator suck it back in. Now the overflow is at low level. But the radiator is full.
Check the bubble with engine running at idle speed after driving it for 4 miles. Saw bubble coming out of the hose in the overflow tank.
Check oil stick was fine, but the oil cap has milky moisture on it.
Then after turning off the engine the fan blade still spin about 1 or 2 cycle.
I thought it supposed to stop with the belt? Fan clutch issue as well??
Sorry for the long story, but I just want to make sure I am clearly describing the problem so I get a better solution/advice.
Thank you in advance.
Should I start looking for HG now or have it rebuilt?
