Re: Putting together oil cooler kit... have some Q's / need some advice
Mocal is good stuff. That's the same size as the cooler I've got, I think. I still haven't installed mine, need to get to that before launching back into the open track season this year.
As for which way to mount the fittings, I've seen that debated a number of times, and I'm not sure there's really a "right answer".
- Some people will tell you that if the cooler inlet and outlet are pointing down, then you'll get air trapped in the cooler and thus at least some of the cooler won't be doing it's job. However, in my junkyard scavenging, I've seen lots and lots of OEM transmission coolers or oil coolers mounted with the inlet and outlet pointing down, so I don't think that's really a problem.
- Some people will tell you that if the cooler inlet and outlet are pointing up, that the cooler will never drain when you change the oil. But others will say that the cooler is siphoned out. I've seen OEM coolers mounted with the inlet and outlet pointing up, too, so I don't think that's a concern. (Although I do think, based on my gut feeling, that the longer the hoses are, the more likely it is that the siphon effect won't be strong enough to suck the cooler dry.)
- I'm pretty sure mine is going to end up mounted with the inlet and outlet pointed to the side. I've read differing comments about that orientation, too, based on whether the inlet or outlet should be mounted higher. I'm not sure it really matters, but I'll cross that bridge when I come to it.
My intention is to mount mine hanging down from the radiator core support. The back of the oil cooler will basically be right against the front of the condenser up on the passenger side. That plan may not survive contact with the enemy, though, so we'll see.
