I HAVE DONE EVERYTHING FROM ENGINE HEAD CHECK PRESSURE TEST RADIATOR REPLACEMENT, THERMASTAT REPLACEMENT, WATERPUMP REPLACEMENT. THE COOLING FANS KICK IN, AND THE CAR STILL RUNS HOT ...WHAT'S NEXT?
ok , but no engine stated. which one>??
hot = lying dash gauge or real hand held pyro IR gun? a $20 tool.
did the scan tool ECT reading show too hot, Yes/no.
no new cap, really?
is the cam timed right?
is the spark timed right.?
is the ECU stuck in limphome mode? (huge heat to cylinder walls)
thermostat not upside down.
or thermostat not with bleed hole up hill trapping air below
making it lie and the dash gauge lie too, (the gauge can not measure air, period)
id not do squat with no IR gun. not me. its super accurate too.
and dirt cheap and saves burned hands,
and finds clogged rad tubes saving useless $250 new rad.
one tool. use it. and win.
i this this dang I6 engine, that loves to trap air?
had 3,now, over 500k miles on them. 1988 to present.
and never overheated but once, pin hole in heater core hose
ran bypass and drove home.
i have a 08 wrangler 6sp, 3.8L v6 , nice rig. easy to fix too.
there are 2 parts. (3 really)
engine make too much heat, (limphome or timed wrong)
air in system.
the rad pressure test pass and the green/blue test passes
no water in engine oil
no oil or carbon seen in the engine coolant , all places look.
how hot, ??????
numbers matter, in all ofscience. they talk to you.
at what exact temp did the fans, kick in,?
the FSM shows you this, and how to do that. how to make sure the
fans kick in happen, RIGHT. some are 2 staged with A/C.
not just kick. (when)
