I've seen a few carriers rebuilt without all the fan shrouds etc. not fitted.Then, they overheat, and you see them (the owners) wonder why.
The flatty is a hot running engine , because the exhausts run through the block.
I have read, that they should run a mono grade oil because it is a better transferer of heat. (A lot of heat is conducted away through the oil. This is why they have a cooler)
When the covers are on, the fan has to stuff all that air through those two square holes in the rear hull plate. When an engine is rebuilt it will generate heat much faster, and needs to transfer it away. This is achieved by attention to detail, descale the water jacket properly, dont take short cuts with the radiator, dont paint the radiator, and if you have to, us the proper paint (which transfers the heat faster that other paint) I'd definately use thermostats, and a coolant additive. (It increases heat transfer,and the boiling point, but can tend to help leaks happen)
Remember these things work hard shifting 4 ton of carrier.
P.s. Bruce you should also have three eyes, and the beginning of a tail (dont ask me to explain this)
