Radiator can't handle the load.. Just make sure the fans are pulling air... One way to see if the radiator is at fault is to try turning the heater on high... If the temps stay cooler the radiator has had it. Turning the heater on in emergency is good to know so I hope this helps.

Wish the best with the chemo... will be praying for her.

Water not circulating radiator engine running hot


Hi ytabaja97,
Sounds like the thermostat on the hose that goes to the top of the motor is stuck closed, or does not open completely. Try replacing the thermostat. Make sure it is correct for your Jeep, and that the seals on the thermostat housing are replaced correctly.
Hope you have no more overheating problems.

I've changed the head gasket (top overhaul),the thermostat,the radiator cap and serviced the radiator where the water is flushed out and replaced and checked for no leaks but still my trooper over


You have a water leak from the sound of it or water is draining from over heating. Things to check for, leaks at the hose connections, leaks at heater connections on engine, leaks at water pump and any leaks at head gasket. Assuming there are no leaks check or replace or adjust your water pump belt. Take the thermostat out and run the engine without out it. If the problem is solved replace the thermostat recommended for you car. You can also have it checked as well.

ouch. leaking fluid and no signs of leak. check engine oil. if it appears milky, you are leaking into the cylinders. this means you'll need a new head gasket.

Why does my cadillac 1998 deville keep overheating?


Overheating can be numerous things: Fans not working, water pump, thermostat, overflow cap, and the list keeps going. When the engine is running and heats ups, feel the heat of the top hose, if the hose isn't hot, the thermostat is most likely stuck open and needs replaced. If it is hot we know you have circulation. The cap on the expansion tank may be defective, if it can't hold the pressure of the water, it will release at the overflow cap if the cap is bad. Also check the coolant level.

Trooper Overheating


Your radiator efficiency has been reduced by (what is called) blossoming. Blossoming is electrolytic growth of crystals inside radiator duct passages. This typically occurs in the older Troops as gradual overheating probs cause the vehicle to run low on coolant, then water is being used to top off system repeatedly, acid levels in cooling system rise as the coolant protectants degrade and the inside of the radiator ducts 'blossom' with small crystalline growths that reduce the radiators flow and ability to cool the engine. Flushing and blowing out the radiator are temporary fixes. Replacing the radiator is the permanent fix. You did the right thing by replacing the water pump, tstat and radiator cap. An old, original water pump usually fails soon after the radiator is replaced. New Trooper radiators are fairly cheap, $85+. The replacement can be done by any backyard mechanic or DIYer in under and hour. You know the typical warnings about the toxicity of antifreeze and the deadly affects on pets who drink improperly disposed coolant. Good luck to you. It's an easy remove and replace. Your Trooper will thank you with many cool running miles. -Geoff

1989 Isuzu troop temp gauge goes straight to hot when key turned


there is a sending unit for the guage.but if it has been running a few minutes and gets hot you may need to check the thermostat or water pump.check the water pump by taking the radiator cap off.then start the vehicle,look into the radiator and see if any coolant is flowing or circulating.do the cheapest fix first

Isuzu car engine overheating


I had the same problem on a Vauxhall Montery (Same Car), The thermostat jams shut thus causing the engine to overheat and damages both the cylinder head and gasket, first thing to check is the enigne oil, pull out the dipstick and check for a white, spongy liquid. If present then your head gasket is passing water into the crankcase, If engine oil OK then fill up the coolant system and give the car a good old rev for a few minutes then check teh exhaust for water. In both cases the cylinder had needs to be removed, skimmed, gasket replaced and thermostat replaced.
