Let me clarify a few things...
The water overflow bottle was to vent the valve cover.
The car does have a radiator overflow bottle.
I know the engine runs between 200 & say 205-207 at
speed on a hot day. I installed an aftermarket
capillary style gauge.
I installed an electric fan as a pusher and I wired it
into the ignition so that when power is switched on,
it's on. I also installed a plastic yellow fan rather
than the metal fan that it came with. I flushed the
system many times. I installed a new thermostat. I
also ran it without a thermostat. Didn't seem to make
What I plan to do this spring/summer is add a radiator
shroud, eliminate the stock fan & make the pusher fan
a puller fan in hopes of unblocking the front, have
the radiator checked out. And if that all doesn't
work, then add an oil cooler/w thermostat.
Just wondering if venting the engine to the air would
keep it cool(er) than not venting?
