Overheating 3208 in a 90SP36

[Mike Hohnstein]

Yo, Johnson, it's NOT an IDEA. It's on my vehicle and it actually works, per my
oil pan temp gage and my water temp gage. Nothing new about, just because it
seems to be unfamilar to you. Just returned from a 4000 mile trip to Idaho and
am going back next month so I get on down the road too. As far as temperature
limits, that's experience, I've got a lot of it and it's OK if you want to
ignore it my advice, it's your engine.

Hello Again Chuck,
Mike's idea about a spray bar will improve cooling capacity on a hot, dry,
day, but not sure
where he gets the max numbers on coolant and oil. Important to remember the
thermostat doesn't fully open until 185ºF. Radiator cap pressure rating of 7
psig, altitude
and coolant composition set how hot you can run the radiator before you boil
over.
Engine oil can safely operate at sustained temperatures of 220-240ºF and for
shorter
periods as high as 300ºF with no problems given normal oil changes.
