Question about 1997 Chevrolet Venture

Chevy Venture Overheating

Van has been overheating for about the past 2 weeks. When I accelerate hard, the temp gauge drops. Two days ago, the temp gauge reached it's limit and the engine shut itself off. In the last 4 or 5 days, the van does not make it more than a few miles down the road before the temp gauge shoots up. I have checked the coolant tank, and it is full, but the fluid appears to be extremely dirty to me. Could this have caused a clog? I have noticed that both fans are coming on, and remain on after the engine shuts off for a few minutes. Also, when I turn the heater on to try to help with the overheating, it blows very cold air, and causes the temp gauge to rise faster. I know that there is a leak in the oil lines somewhere. Could that also be the culprit?

Almost sounds like the same symptons as my van. Turns out the guage was not the problem. The van was in fact running hot because the electric radiator fans were not kicking in when the engine was hot. I replaced the relay switches for the fans. There are two of these in the fuse panel under the hood. There has been no problem with overheating since

Overheat and accelerating automatically


Time to change the thermostat if you not already have done so. This is the cause of most overheating problems, although a good radiator flush may solve the problem also. The fan will stay running until the engine coolant reaches the proper parameters and then shut off.

you have 4 water lines, they are 2 radiator hoses (top and bottom) the bottom one runs from the lower part of the radiator to the water pump, the top radiator hose runs from the upper part of the radiator to the thermostat housing

2 heater hoses, they go from the water pump to the firewall.

if you know which one has a hole then you should take the van to a parts store (if you can safely drive it that far) and show them, they can get the right one for you... and sometimes you can talk someone into putting it on for you.

as for the fluctuating gauges you probably need new sending units for the temp gauge and fuel gauge

Radiator fan not stopping even when i turn off the car and remove the keys. this is leading to battery drain


Radiator fan is supposed to start working after the temp reaches a certain limit. And it is supposed to run til the temp reaches a certain lower limit. So when you switch off the engine and walk off the fans must be running to cool the water to that lower limit. Unless you seen that it runs well past that and does not stop at all. Does it start running when you start the engine? And runs throughout the time the car is running, which it should not. The relay seems to be out. It is this relay that controls the running of the fan. or the temp gauge. If the temp gauge is giving wrong temp then the relay has to keep working. Please check both, the relay and before that the temp gauge.

is it acually getting hot or is it just the gauge on the dash saying so? a quality scan tool can show you what the coolant temp sensor is telling the pcm it may differ from the gauge.
