Sometimes the float in the low coolant sensor gets stuck.Find where the electrical connector is on the overflow tank and lightly tap on this area.This might dislodge it,if its stuck.Good Luck!!!

I have a 1997 pontiac grand prix gtp supercharged coupe my power steering hose popped off and i put it back on do i need a new one or is the pump gone i need help cuz its hard to turn


if you put the hose back on and put new fluid in it and it it is still hard to turn which means you pump prob went bad , make sure you have enough fluid in it first, you could have blown you rack and pinion but not likely

1997 grand prix gtp. Tire pressure/abs light


Hello! This indicates a fault with the wheel speed sensor/ABS sensor. Any major auto parts retailer can pull the details of this code (which sensor) for free, which will help you identify if the wiring is loose or damaged or if the sensor will need to be replaced. If you need to replace the sensor - you will need to replace the entire wheel bearing assembly, as the sensor is internal.

1997 pontiac grand prix gtp power steering


I had this exact car and I had all the same problems your talking about, The pump although I can't tell you for sure is on the left side of the engine as your looking at it. If it is whining it is because it is low on fluid, also when topping it off fill it to the full mark while it is running. If it is foamy turn the steering wheel all the way left and all the right a few time to help get rid of the air. You may have to let it sit a while to let the bubble escape, check and do this again, it could be a bad pump also. The overheating problem I had with mine was a bad temp sensor for the computer. It has two temp guages and the computer uses on to activate the fan as needed. I also had another problem with mine, on the front of the intake is a small plastic elbow for a heater hose and this goes bad. Had to replace mine. Wasn't hard, and the part was cheap. Hope this helps you!
