Good Evening. On your Bonneville you will need a 10mm socket (preferrably a deep socket), an extension, a swivel and a ratchet. In the area it is I have found it is easier with an extension. Firmly grasp the neck underneath your oil cap and turn it counterclockwise, and then remove the plastic decorative 3800 cover. Follow the upper radiator hose the one on your right standing in front of the car, once you reach the end where it attatches to the engine that is where your thermostat housing is. From there it is self explanatory, just be sure to always use a new gasket around your thermostat. Good luck and hope this helps.

I hace a coolant leak that comes from a line that comes out of the engine and 90s into the base of the serpentine belt tentioner. I dont know name of coolant line to replace it but I can see it leaking and...

It Is probably a "Coolant Bypass hose" If its possible...take it off and bring it in to an auto parts shop and have them match it up...some cars have "Several" coolant by-pass hoses. A Site might help you identify the hose as well

Go to it and Click "pontiac"
Click "1997"
Click " Bonneville SE" or "SSE"...then click "Cooling System" and then click "Coolant Hose"
Click the various pictures in hopes to "Spot" the one thats in your car, And read the label as to what its called or even get the part number!
I hope this info has helped you out
