paul mac Posted March 1, 2008 Share Posted March 1, 2008 Is there a right way to mount it? Pipes to the top or bottom? I tried searching but couldn't find an answer... i would keep the pipes to the top, you may cause an airlock with the pipes at the bottom but that is probably unlikely Quote Link to comment Share on other sites More sharing options...
Hermit Posted March 1, 2008 Author Share Posted March 1, 2008 It's just that it would be easier to have the pipes at the bottom, because routing the pipes would be neater, and I'd have enough pipe already. But I think you're right, why risk an airlock. Thanks! Quote Link to comment Share on other sites More sharing options...
uk-rich Posted March 1, 2008 Share Posted March 1, 2008 Mine are at the bottom with no probs as yet Quote Link to comment Share on other sites More sharing options...
Hermit Posted March 1, 2008 Author Share Posted March 1, 2008 I guess with an airlock it would just not be as effective as it could be, nothing immediately noticable (in my case anyway). BTW It's a B&M transmission cooler in case that makes any difference. It came with some fitting instructions, they don't specify a preferred orientation for it, but they're very minimal instructions.

dini_the_owl Posted March 1, 2008 Share Posted March 1, 2008 inlet top and outlet at bottom Quote Link to comment Share on other sites More sharing options...
Tricky-Ricky Posted March 1, 2008 Share Posted March 1, 2008 With the amount of flow and pressure that goes through them an air lock is very unlikely, how many people have remote filters fitted upside down;) Quote Link to comment Share on other sites More sharing options...
paul mac Posted March 1, 2008 Share Posted March 1, 2008 Hermit hope this helps, a tip for the future if you get no bites on a tech query just throw a contraversial worm in, these guys then take the hook every time Quote Link to comment Share on other sites More sharing options...
Hermit Posted March 1, 2008 Author Share Posted March 1, 2008 inlet top and outlet at bottom Not like this then? http://www.bmtrans.ca/cooler.gif With the amount of flow and pressure that goes through them an air lock is very unlikely, how many people have remote filters fitted upside down;) What pressure is transmission fluid at anyway? It's a plate and fin design like this one, so the oil could find it's way through without using all the pathways. http://www.bmracing.com/media/products/items/382_full.jpg Quote Link to comment Share on other sites More sharing options...

I did say True, not in the first post though. to be honest fella i would not get bogged down to much with this, i run twin transmission coolers and the hoses are like spaghetti junction, the only reason i traced back to see which was feed and return was for mounting the stat for the cooling fan, i have no idea what goes where on the other cooler and it all runs fine Not really bogged down, I've been doing other stuff on the car today, just about warmed myself up again now it was damn cold in the wind! If it doesn't matter which way up it goes then that's fine by me Quote Link to comment Share on other sites More sharing options...
David P Posted April 28, 2010 Share Posted April 28, 2010 (edited) I have resurrected this old thread because; I am fitting oil coolers for engine and transmission, and it is much easier to mount them with the hoses at the bottom, but concerned that the coolers will hold air. With a permanent air pocket at the top, the cooler would only partially function, and oil pressure received would lag behind pressure delivered by the pump. I have hunted the net for info yet found nothing other than this post. Does anyone have definitive information?

mwilkinson Posted April 29, 2010 Share Posted April 29, 2010 My pas cooler is mounted upside down and no I'll effects thus far. Cleared the air pocket when I bleed the system. It's a setrab cooler if that's of any importance. Quote Link to comment Share on other sites More sharing options...
j80leo Posted April 29, 2010 Share Posted April 29, 2010 My oil cooler has the pipes at the bottom and no problems;) Quote Link to comment Share on other sites More sharing options...
Stephen G Posted April 29, 2010 Share Posted April 29, 2010 the oem tranny cooler on my uk spec the pipes are at the bottom so if its good enough for mr t that way i think it should be good enough for everyone. Quote Link to comment Share on other sites More sharing options...
David P Posted April 29, 2010 Share Posted April 29, 2010 (edited) There are coolers that are an S S pipe with cooling fins, and there are coolers that are II======II II======II II======II II...........II 2 in/outlets into a finned cavity. With the continuous S pipe design, the air would be pushed straight through, but with the other form, mounted with the pipes at the bottom, I can't see how ther air could possibly be bled, just compressed into a smaller pocket at the top when under pressure. Household central heating radiators are fitted in this way, and to remove the air lock, need bleeding from a valve at the top. Unless the exit pipe extends inside the cooler to the top, how could an oil cooler be without the same physics?
