I just recently got my Renesis started again after finishing
my cowl. I seem to be getting very high coolant pressures. I can
only run the engine about 10-15 minutes before hitting the redline at
210*. My water pressure is at 27 Lbs at that time. I only have a 22
Lb radiator cap, so I assume that I am blowing into the recovery tank, but I
have not confirmed that. My oil temp has never exceeded about 165*.
It might have gone higher if I could have run longer???
This whole water pressure thing has me a little
baffled. Since this is a closed system and the only way pressure can
build is due to the expansion of the coolant after heating???, I am confused by
some comments that have been made from time to time. I remember something
that Tracy said
about his pressure would build for a time, then go to zero. It seems to
me that the pressure should correlate to the temp pretty closely since it is a
closed system??
Can someone enlighten me a little on the science of this
pressure? It seems to me that there could be some pressure build up on
the positive side of the pump, but it would go negative on the suction side, so
the net effect of the pump should be close to zero??
Also, my Renesis had only 1800 miles on it when I bought it,
so I did not have to tear it down. As a result, I am somewhat in the dark
as to how the water flows through the system. Could someone help me with that?
I had to remove the thermostat tower for height clearance , so I made an
adapter plate that takes water from the top outlet of the pump and sends it to
the radiator (double pass), then from the radiator, it returns to the lower
inlet of the pump.
Thanks,
