1997 suburban overheating

The upper hose blew up and got really hot. We replace the hose but it's been overheating since then. It takes two to three minutes to overheat. I would like to know possible causes for this and of course the solutions. I live in utah and it's relly cold right now, it's beeing snowing. I don't know if this has something to do with it. I put water in the radiator to see if it was licking but is not. I noticed that when removing the hose from the top of the radiator, and turning on the engine, water wasent going trough. any help and ideas would be really apreciated, thanks

Hi my name is Allen. Your hose blowing like it did can be 2 different problems. One your thermostat could have stuck causing it to overheat to the point of building so much pressure within the radiator that it caused the hose to blow. The other possible cause is you may have a blowed head gasket which is very expensive repair. The water not moving through the system with the hose off, could be because the water is going in the oil pan, pull the oil dipstick and check to see if the oil looks milky like a real light tan color and if the oil is way above the full line on the dipstick. If it is you have a blown head-gasket. If it is not, I would suggest replacement of the thermostat and see if that repairs your problem. You may contact me for futher assistance through FixYa.

I have a 2000 Bmw 323 I that is having a overheating problem what would be the cause of the overheating problem a thermastat a water pump or a radiator flush

Could be any or all three or a bad cooling fan. I'd start by replacing the thermostat since they are dirt cheap. After replacing the thermostat warm the vehicle up and feel the upper radiator hose if its hot the rhe thermostat opened and the water pump is circulating coolant next check the radiator it should be hot near the upper radiator hose and significantly cooler near the lower with an even heat distribution if any parts of the radiator dont get warm/hot then you radiator is plugged. Also you need to check the operation of the cooling fan with the engine warm turn on your ac that should immediately turn the electric fan on

Where is thermostate located on 1997 suburban

Follow upper radiator hose from top of radiator to engine. It attaches to thermostat/water outlet housing. Remove hose clamp. Remove two bolts beneath hose that attach housing to intake manifold. Under this housing is your thermostat.

2002 Jetta 1.8T blew 40A cooling fan fuse - overheated, destroyed 4 way cooling hose connector - replaced all- now it still runs very hot, inside temp reads 190 (but temp is much higher), cooling fans run...

Then replace the thermostat, because if on lower hose not hot and on upper hose scalding hot = antifreeze flow blocked by the thermostat wich remains closed!!!

!997 chrysler town and country LXi 3.8L is overheating and it blew a hole in a hose on top and after i changed the hose it blew a hole in another hose on the bottom.Is this a water pump problem??

If the hoses were in good shape and they blew you may have a clog in the system most likely the radiator. You take the van to a good radiator shop and ask them to flow check your radiator.

Waterpump went out and engine got real hot and blew upper radiator hose replaced waterpump and hose now it wont fire

It is very likely the overheating has blown the cylinder head gasket and coolant is getting into cylinders or compression is leaking from cylinder to cylinder or both, you will need to remove the cylinder head and have it checked for warp-age and shaved flat by a machine shop if ness, and replace heat gasket.

1997 cadillac sls overheating

Allow it to cool down and refill system while running with heater on hot. Hopefully this will get the air out of the system. However, if this condition persists, have the radiator checked for hydrocarbons. These engines are sensitive to overheat and you may have blown a head gasket. (hope not)
Good luck!
