After doing some research, I think I have a bad water temp sensor that is mounted on the water pump. Do the local part store sell them or do I have to go to Pontiac to find this. I can stop at Pontiac on my way out and grab it if needed. Is it expensive?

Thanks!

No it isn't expensive and the dealership should have it in stock.

 

Screw going to the dealership for something so simple. GP Sorenson part# is TSU81 and it runs like $8.99 It's the same one GM used on about everything during most of the 90's and late 80's.

 

Yea local parts stores have em, i did a buddys opti and WP and we got one at schucks.

 

Get it at Autozone for 8 bucks. I just replaced one.

 

picked it up for 8.99 tonight...found it at advanced auto....thanks guys! Should get it in tomorrow...hope this cures the stumbling problem.

 

Yep, I used to run an Advance Auto lol
