Re: cooling system is being a pain. Info would help please

Stick in a new thermostat. If you get good readings on the second
thermostat, chances are gauge is correct.

Car comes with two bleed lines: at high points of radiator and block
(via heater core supply). These purge air continuously. Is a bleeder
valve at high point of whole system (under thermostat), but is not a
continuous purge. What many owners do is replace that valve with a
hose barb and run one more bleed line to a tee inserted where block
bleed empties into coolant expansion bottle. With all high points thus
covered, all you have to do is fill (remember: 50/50 mixture cools
better than pure antifreeze) and run the engine. System will bleed itself.

While you're working on cooling system, don't overlook what may be
factory original hoses and seals, especially in hidden or hard to
reach places.

John Hervey (www.specialtauto.com) sells otterstats with variety of
temperature ratings.

PRV runs surprisingly warm. Long after engine shut down you're still
burning your fingers. After you've verified gauge reading correct (and
cooling system purged of air) rely on it, not radiant heat from the block.
