Oil cooler, duh heater, seals?

[3d914]

I'm looking for the seals (two of them) for the oil cooler. Know any suppliers? The online ones I've checked don't even list the part, much less the seals.

Also, in one of the manuals I have, it shows the oil cooler (front of block), but isn't this thing really an oil heater. Heated coolant from the block goes directly into the "oil cooler" then out to the outlet housing. Or is the thought that the coolant temp is lower than oil temp - thereby "cooling" the oil. Just curious!

TIA,

Average oil temp is 212 degrees, and that's what you want it at, so the coolant does help keep the oil cool. Oil actually helps keep your engine cool just as much as coolant.

It's both. After cold start, the coolant tends to warm much more quickly, so the coolant will heat the oil during the warmup phase. Once everything is warm, the oil will shed heat into the coolant, especially at high loads.

The stem in the SHO oil cooler has a very slick viscosity bypass valve that bypasses very cold, thick oil around the cooler to lessen the chance of the cooler bursting in extremely cold temps. It performs much the same function as a bypass valve in an oil filter.

You can use a standard oil filter gasket or an o-ring; it's just that the o-ring is hard to keep in place as you put the exchanger back against the block. The little o-ring around the stem is captive in the exchanger but you could use a standard o-ring for that also.
