Question about 1999 Oldsmobile Intrigue

1 Answer

Overheating Intrigue on my 1999 Intrigue 3.5 Motor I have replaced recovery tank, antifreeze, water pump, radiator, and thermostat. Car still over heats after running for approx 10 minutes. Fans are working and I have wired them to help them engage early to see if if would keep the temp. down. Over heats still with the heater blowing on high. No smoking from tail pipe. I am suspecting head intake gasket. Car was doing fine. Had a cracked recovery tank. Overheated a few times (perhaps a few times to many) Any ideas? Also are the 4T65-E automatic transmission interchangable from 1999-2002 Thanks ask4mrbiggs@hotmail.com

    Thanks,

    I will perform the cracked head test as soon as the weather warms up. Would this worked for a blown intake gasket as well?

Check your coolant level and see if it is down. If you have checked heads you will notice your engine oil beginning to turn milky white.

If you want a more complete check for cracked heads, plug all spark plugs, and if you can get a coolant pressure tester, pump it up to 12 or 13 psi and then crank the engine over. Watch for water to spray out of one of the cylinders.

COULD BE THERMOSTAT IF TOP RADIATOR HOSE IS NOT HOT AND BOTTOM RADIATOR HOSE GOING TO WATER PUMP IS HOT THE THERMOSTAT STICKING PARTIALLY CLOSE.IF TOP HOSE IS HOT THE RADIATOR,ENGINE BLOCK HEATER CORE NEED FLUSHING OUT.IF WATER PUMP WEEP HOLE LEAKING REPLACE WATER PUMP, FAULTY WATER PUMP WILL CAUSE ENGINE TO OVER HEAT.REPLACE RADIATOR CAP MAKE SURE YOU HAVE 50 / 50 MIX SOLUTION ANTIFREEZE AND WATER IN COOLANT SYSTEM. IF ALL LOOKS GOOD CHECK ENGINE OIL ON DIP STICK, IF OIL IN DIP STICK LOOK LIKE MILKSHAKE YOU HAVE BLOWED HEAD GASKET THAT WILL CAUSE ENGINE OVERHEATING WHILE DRIVING CAR IN SHORT DISTANCE AND ENGINE OVERHEATING.

The car keep overheating, there is water in the radiator and the resevior tank 2000 jeep grand cherokee i check the oil their is no water found in the oil the water from both unit stays full


Sounds like your thermostat is stuck closed. Shouldn't be more than a $20 part from autozone and is simple to replace. Follow your top radiator hose to the motor and it will connect to your thermostat housing. Disconnect the hose (antifreeze will run out) unbolt the housing, and replace the old thermostat. Refill radiator and bleed the system.

1999 buick centry overheating overflowing the overflow


Until you get it figured out use regular water. Replace thermostat and radiator/coolant tank caps. Thermostat regulates pressure in the motor and allows radiator to cool. Caps regulate atmosperic pressure. Either or both being bad will cause you system to siphon and fail.

My car was overheating so i took off the thermostat and replace a hose that was leaking but now car hasn't overheat yet b water comes out through reservoir tank what could be the problem now?


the water is getting to hot even though its not overheating because you need a thermostat to trap the water in the radiator to give the water a chance to cool down then the thermostat opens and the cold wanter enters the motor and the hot water in the motoer enters the rad. to cool down. with no thermostat, this doesnt happen it just circulates and warm up to the temp it warms up to and is at the same temp in motor and rad then to hot will come out the overflow, as a resualt, you will wind up losing antifreeze then wont have enough antifreeze in your engine then will damage your engine.Put a thermostat in and a water pump. fix it right or you will damage your car.

My 2000 old 3.5 l intrigue overheats at 1500 rpms and below. I have changed throttle body gasket, thermostat and water pump and it still is overheating. Where do I go next.


The orange antifreeze that is used is know to gel up and after a few years when the mixture is no longer 50/50, the antifreeze will crystallize and plug up water journals and jackets. The orange antifreeze has a life of 5 years or 150,000 miles and any longer will have the cooling system plugged up with crystals. Best thing to do is to flush out the cooling system with Preston coolant flush, use the dry powder to flush the system out and follow the instructions, then replace the coolant with 50/50 (water/antifreeze) mix. If your not sure how to mix, you can buy them premixed. This should help keep your cooling system 100%, keep me posted. Be glad to help get your car running 100% and you could also replace the temperature sensor, it's located at the manifold just in front of the thermostat housing. The tip of the sensor may have crystal formation, giving it a false reading.
