Angelo,
I am running a standard 4lb cap from NAPA. Have not had any serious
problems except that if I put it under pressures like accelerating up hill
at freeway speeds it will climb about 10 degrees beyond normal and some
coolant will release from the cap. I am not sure what the cold level is for
coolant so I may simply be overfilled a bit.
Most of my driving is at higher elevations, 5,000-8,000 feet so I am not
sure if the lower boiling point would call for a heavier or lighter cap.
Perhaps there is an expert out there that could help to explain the
differences.

Subject: [TR] TR2/3 rad cap pressure
Hello List:
Seems to have been quiet on the list the last couple of days. Wondering
about rad cap pressures for the 2/3 engines. My '2 came with a 7lb. cap.
I thought they were supposed to run a lower pressure cap. Any thoughts?
Am I OK with the 7lb. cap? I have a couple of good long reach 7 lb.
caps, so wondering if I have to go with something else.
Thanks in advance,
Angelo Graham
