You may have a problem with the coolant passages in the intake manifold clogging. also i have seen intake gaskets installed incorrectly causing coolant circulation to be impaired/ check for air pockets

My 97, 5.2 runs 200 without AC, if I turn on AC, it goes to 220. Replaced clutch fan, thermostat, water pump, and new cap. Backflushed block and radiator. No results. Why so hot? Only 92K on unit.


dodges run like that. if your worried put a 180 degree thermostat in. maybe even a 160 . wont hurt engine or fuel mileage . my 99 dodge ram 1500 sport runs fine with 160 degree one. hope it helped , good luck

Filled Coolant reservior and radiator Drove trailblazer at highway speed no cooling problem. When slowed down in traffic temperature increased to about 220 and higher, could hear coolant bubbling in...


If there is bubbles occurring even inside the top part of the radiator (where you have the coolant put in), you may have a leak on your head gasket. You may be loosing coolant through the engine.

Possible fan clutch..Usually if its a fan clutch it will run hot sitting still but cool off once going down the road..If it takes a while to run hott then i would suspect a clogged radiator..When you drain it did it look like all the antifreeze came out..Ive seen half the radiater clogged up where half of it drained but the clogged section stay in the radiator

REPLACE RADIATOR PRESSURE CAP AND CHECK THE COOLING FAN CLUTCH.WHEN YOUR ENGINE HOT WHEN YOU TRY TURNING CLUTCH FAN WITH YOUR HAND WHEN ENGINE IS HOT.THERE SHOULD BE RESISTANCE IN THE FAN.IF CLUTCH FAN SPINS FREELY WHILE ENGINE HOT.YOU NEED TO REMOVE COOLING FAN TO REPLACE CLUTCH.

Car will run ok for about an hour, then gradually start slowing down till stops. after it sit for awhile it usually starts up and run ok until it has another episode


SOUND LIKE ENGINE GETTING TOO HOT.CHECK THE COOLANT AND THE FAN CLUTCH.IF FAN CLUTCH HAS RESISTANCE WHEN HOT ITS GOOD.IF FAN FREE WHEELS WHEN HOT REPLACE IT.IF FAN CLUTCH GOOD THE THERMOSTAT FAULTY.RADIATOR CORES SLIGHTLY STOPPED UP. CHECK RADIATOR GRILLE MAKE SURE ITS NOT STOPPED UP WITH DEBRIS.

Overheating intown or towing


You might laugh, but have you put a new rad cap on? If the system is not holding enough pressure it can overheat.

1990 Ford Mustang GT Still Running Hot!


check to see if you can spin the fanwhile the engine is cool it should spin freely,if it doesnt fan clutch,also I would switch the fan back to oringinal just to test if this is the problem,if it is youll have to design a different fan shroud if you want to use you new fan,if everything done above is ok with the engine cool take off the radiator cap and squeeze the bottom hose 4-5 times in burst this will make sure you dont have air in the system,if this is helpfull please vote me a fix ya
