Or, if you run a TP by pass oil filter, the filter removes the water from the oil and holds on to it. Water is needed to form acid, so if the water is removed acid doesn't form.

Remove the gauge, install the factory temperature light, and enjoy your car worry free for the rest of your life.

My '67 has the light and it never runs hot or overheats. :)

Run it and stop worrying about it getting above 200 degrees with the A/C blasting.

Even 220 isn’t that bad.

Once it hits 220 or 225 then shut off the A/C for a while.

197 degrees is nothing.

I may be wrong. I'm not an expert in Pontiac axle options, and I'm too lazy to dig out my Chevy references.
