    ok I just drove it for a good 45 minutes and it still was bouncing back and fourth to cool and hot, when I stopped the car and shut it off no smoke, and the engine was fairly cool and radiator did not smell or was even massively hot as it should be if over heating is occurring, I am wondering if my gauge is out of whack some how.

Well you might have an intake manifold leak or teh heater hose niple that goes in the intake these are the most common coolant leaks on these engines.

YOU HAVE AIR TRAPPED UNDER THE THEROSTAT
THE BEST WAY IS TO DRILL A 1/16" HOLE IN THE FLAT RING OF THE THEROSTST THAT WILL ALOW THE AIR TO EXCAPE AND KEEP YOUR MOTOR COOLER

LOOK UNDER HOOD AROUND RADIATOR AREA FOR LEAKS AND CHECK FOR LEAKING RADIATOR HOSES.CHECK TOP RADIATOR HOSE TO THERMOSTAT IF HOSE LEAKS THERE YOU WILL SEE A LOT OF SMOKE AND STEAM WHERE COOLANT SPRAYING ON HOT ENGINE.

My s 430 has smoke coming from under hood after driving but not all the time temp gauage reads normal. I had oil and trans leaks sealed but it is still happening, what else could it be? Thanks


SMOKE UNDER HOOD COULD BE COOLANT LEAK FROM RADIATOR ITSELF OR CHECK FOR LEAKING TOP RADIATOR HOSE AND CHECK FOR LEAKING BOTTOM RADIATOR HOSE.LOOK UNDER THE HOOD IF COOLANT BOILING OUT COOLANT OVERFLOW JUG ENGINE OVERHEATING FROM BAD THERMOSTAT OR BAD WATER PUMP.CHECK FOR COOLANT LEAK AT WATER PUMP WEEP HOLE.IF SO WATER PUMP NEED REPLACING.ADD MORE COOLANT UNTIL LEVEL CORRECT.TRY LOCATE LEAK. IF CAR OVERHEATED AND BOILED IT OUT. SMOKE UNDER THE HOOD CAN ALSO BE CAUSED BY LEAKING VALVE COVERS WHICH CAN BE FIRE HAZARD IF OIL LEAKS ON HOT EXHAUST MANIFOLD.

Turned car off...sounded like it's trying to start w/o keys


This is called run on,or dieseling ,there maybe a timing problem,or the vehicle is running to hot,the temperature is to high,it may not be cooling good,check the temp of the engine,if it is too hot,then the cooling fan may not be working,or thermostat maybe staying closed.If the vehicles throttle is staying open to much,this could be the problem also.

Temp gauge went to 260 & stayed there. What could be the problem?


The only real way to answer your questions is for you to open the hood and look it over. Once it has cooled down, re-fill the cooling system (use water...it's cheaper and to do repair you will need to repalce it anyhow...Once full carefully look everything over to find where the leak is.Also make sure that the drivebelt is there. (from what you said, likely it is) If it's water pump, you will see coolant running out from under the pulley. Once you have looked everything over, if you have not found leak, start engine and close the cap...look again...as pressure builds, small leaks will become more obvious. If you don't find leak, remove the thermostat and change it.
After changing stat, if problem persists, it's likely that you have either a plugged radiator or an internal engine gasket problem. If you have any auxiliary electric cooling fans, make sure they are working and also check the fan clutch on the mechanical fan (it should not excessively freewheel when hot). Whole testing, any time you replace the radiator cap you must allow engine to cool down before removing it again. Watch temp gauge while testing...don't allow engine to overheat.

Still running hot


Is it just reading hot on the gauges or is running hot from under the hood.

2002 GMC YUKON COOLANT KEEPS EVAPORATING


if you dont see antifreeze leaking anywhere,its the head gasket,check your oil dipstck,the antifreeze is probally mixxing with the oil as it leaks thru the gasket and will give the oil a milky white color on the dipstick,if you start to see white smoke from the exaust then its leaking into your exaust port,either way head gasket and change as soon as possible,you dont want it in the oil cause you can seize the motor
