  • Welcome to Forever Pontiac

    We are a community of Pontiac enthusiasts. The purpose of our community is to keep alive the Pontiac spirit by sharing (or showing off) our cars, discussing Pontiac, helping each other work on our cars and find information, plus attend various meets/shows/etc... To aid discussion, sharing, event planning and selling of parts/cars/anything, we have various parts of the website to aid this from Forums to an online Garage to Classifieds to even a Document Download Repository. You can find links to these in our navigation above based on what each section helps with (discussion, local events, learning, etc...).

    We invite you to contribute, find help or just view some of our member's amazing cars! Don't forget, we also have great contests from time to time (like our Pontiac of the Month and yearly calendar contest) and our Pontiac This OR That, a fun game where you choose the best of two randomly selected Pontiacs from our online garage.

    We look forward to seeing you around!

How long have you been monitoring your coolant? Has it increased like this before, if you have been for over year, near summer time and when its hot out?

These temps aren't real significant difference but I'd keep an eye on it and as well check you fluid levels every now and again.

What's the mileage on the car? The condition of the DexCool coolant in there? It's possible that the thermostat could be starting to stick.

i agree sounds like a sticky thermostat.. or possibly blockage else where

i dont know much about these cars though.. but there could be the possibility of running to cool on highway due to your thermostat staying open to long
