@Michael McKelvey posted:The first thing I plan to do is slot the holes in the alternator stand close to the shroud and replace the studs on the other side with bolts. Then, if Andrig's fan doesn't work out I can swap it without pulling the engine and shroud.
I tried this a few years ago and it has been helpful when changing alternators. All bolts might be better since you're less likely to damage the gasket sliding the alternator stand around. I like @Stan Galat's point about adding time-certs if the opportunity presents itself.
On the topic of oil coolers, I don't see a good reason for keeping one inside the shroud. It just contributes to the heat load and temps inside the engine compartment. I got a 36hp shroud, blocked off the internal cooler and put in a thermostatically controled external cooler with a fan in the wheel well.
