My Mechanic keeps replacing the heater cores under the 6 month
warranty, so that isn't a problem - except I am tired of drying out
the carpeting.

Where would be a good spot for a pressure gauge?

I have a plastic "T" where the core was, so I may leave that in till winter.

My real concern is blowing two differential coolers - a metal part.
Perhaps this is a separate problem from the heater cores?

Thanks,
Paul
