Why does my 1997 Buick Park Ave. stall out when the engine cooling temp. reaches between 208 and 212F.I have replaced many parts and no change.

I just posted my experience in another place on this site but on my 1992 PA the accessories relay stuck closed. This relay is the one that allows you to listen to the radio etc and keep things on until you open the door then all shuts off. When it is stuck closed accessories keep running until your battery drains dead. The relay was replaced and all worked great.

Order the exterior door handle AND the clip that attaches the rod to the exterior handle from your local dealership ( any part in the salvage yard will have at least as much wear as the one U are replacing ) Also order a can of touch up paint matching your car. After you have the parts and have painted the new exterior handle, roll down the window and remove the interior door panel. ( instructions have been posted at 'replace door lock buttom' ) Two nuts, one on each side, hold the broken handle in place and must be removed ( DON'T loose them ). Loosen the rod from the clip at the top to allow a bit more room, But take note on the way it is attached ( you will need to reattach the rod to new handle ) To install new mechanism put the new clip on the rod, carefully place the gasket and the new handle in place and install nuts to secure. Test the door handle and make sure it works. Reinstall interior door panel.

It is in front of the radiator, right below the latch on the hood.

It could be the crankshaft sensor. That's what my 2000 was acting like until it was replaced.
