Engine Swap

[rwoodysurplus]

I totaly agree don


but i dont have room for a side rad--so I have to run it in the rear
of the coach. We will build a tight fan shroud and see the results.

going to give it a shot....

thanks!

that a typical pusher with side-mounted radiator will quickly overheat
if there is not a very large booster fan to suck lots of air in. Any
natural flow is way too weak. In my case, just going down a flat road
with the fan idling at 600RPM I see about 1 degree of temperature rise
per 5 seconds until the fan kicks into high speed.
