Greetings,
In trying to make sense of
my latest cooling problems, I've thought of yet another variable (just what I
need <g>). When I initially installed the new Setrab oil cooler
(behind the radiator), the oil temps never got above 180F, even in a climb to
10000 ft. The water temps were being controlled by the thermostat, so they
were 180 as well. Since then, I've tried to even up the water and oil
temps, by blocking off part (half) of the radiator, and removing the
thermostat. The goal was to figure out how large the Rev 2 radiator
needs to be. The initial indication is that this may have caused my oil
temps to be high. Water is up to maybe 160F max, so there
still seems to be too much radiator, but oil will top 220F if
allowed.
What has just occurred to
me, is that by blocking off part of the radiator, and raising the water
temp, I'm probably increasing the air temp that the oil cooler sees behind
the radiator. Has anyone measured the air temp behind the
radiator when the water temp is around 160 or 180? I'm curious just how
hot this is.
Bottom line is that I'm
thinking I may have to put the oil cooler in front of the radiator,
and leave the radiator oversized enough to compensate for the hot air from the
oil cooler. FWIW- if you've got the space, I highly recommend
keeping the oil and water cooler separate, as most everyone (with sense)
knows already :-)
Cheers,
Rusty (need beer to cool my
brain)
