Can a bad heater core cause your vehicle to overheat? I have a 1994 GMC Suburban


I WOULD SAY NO BECAUSE WATER ONLY CIRCULATES WHEN YOU TURN ON THE HEATER, BUT IF YOUR VEHICHLE CONTINUES TO OVERHEAT IT COULD BE 5 THINGS. CLOGGED RADIATOR,RADIATER HOSES.THERMOSTAT,RADIATER FAN SENSOR OR THE WATER PUMP

No flow in raditor


The radiator or a hose is blocked or the water pump is defective or the thermostat is stuck closed.

I have a vito van and i had to change the radiator so i put theb raditor on cheeck the pip but the water flow is not flowing thought as it should what else can i try and how do i bleed the raditor


If the water is not flowing through the radiator then it could be caused by a couple of things. The first and most common would be the thermostat is not opening. The thermostat opens and lets the water circulate. I believe that on these vans you can follow the top radiator hose to the engine and there will be a cover that is held on with 2 or 3 bolts. Remove this cover and replace the thermostat with a thermostat from the dealer. This is about the only part that I buy from the dealer. But the ones at the parts stores are not near as good. You have to replace them about every year. If it is not the thermostat then it is more than likely the water pump has gone bad. The water pump is what circulates the water through the radiator.

Where is the thermostat located on a 91 Bonneville 3.8 liter engine? The engine overheats when stopped and the fans do not engage. I suspect the control thermostat but cannot locate it on the engine


THE CHEVY 3.8 A GOOD ENGINE BUT YOU CAN;T LET THEM OVER HEAT EVEN ONCE THE INTAKE MANIFOLD IS ALUMINUM AND TENDS TO WHORP CAUSING THE HEAD GASKETS TO LEAK IN TO THE CYLINDERS ANTIFREEZE YOUR T STAT IS LOCATED ON TOP OF ENGINE LOOK AT TOP HOSE ON RADITOR FOLLOW IT BACK TO THE OTHER HOSE CLAMP ON THE HOSE THATS WHERE IT IS ALTHOUGH YOU PROBELLY NEED A NEW RADITOR AND A COMPLETE FLUSH OF THE SYSTEM YOU MAY WANT TO THINK OF GETTING RID OF IT WHILE IT STILL IS RUNNING SORRY HOPE IM WRONG BUT YOUR T STAT IS NOT THE OLNY PROBLEM GOOD LUCK

What should be the heat temporture on a 5.7 motor ?


The temperature should be running in between 200 and 210 degrees and the easiest thing and cheapest would be to change the thermostat try that out and let me know also if you get a chance if you can rate me if your satisfied.

Thanks,

How do i flush the raditor on a 99 GMC Suburban


I think you may have a hex head plug in the bottom of the radiator, although they do not now offer this option for draining... If so, get a long 1/2 or 3/8 extension with a 14 or 15 metric socket and loosen it after removing the fill cap. Make sure it has cooled down... else, you will have to loosen the lower water line from the radiator to drain... you should do this again wiht water into to get the best results... remember the water will not enter the block fully until the thermostat is open ie you must refill and check several times when refilling... put you new antifreeze in first then finish with water.. or you may mix small amounts ie, 1/2 gall at a time to get a 50/50 mix. good luck

My 91 suburban does not start or stay running , intermittantly . The fuel pump and filter was changed but the problem remains . also if I do get it started it runs fine for a while then starts bucking and...


I have a 91 suburban and it wont hold idle. I am waiting for and egr valve. if that fixes it i will let you know. I was told that they can have an internal vacuum leak therefore being difficult to detect.
