Oil cooler. Which way up?

Done abit of searching for the answer but nothing definitive has popped up. Will be getting an oil cooler or two and does it matter which way to mount them?

Ie fittings at the top or bottom or side.

For me personally fittings at the side or the bottom would be best.

Instructions in mine was set to the side as the preferred method but I'm pretty sure it also states you can mount it any direction.

4-7bar of pressure from your oil pump, I dont think it'll matter hugely with way you mount it, either way, oil is going to be forced through it at some rate too

Nice one cheers

If you mount it any other way than with the fittings on the top you MUST be sure your oil filter has an anti drain back valve inside. This is one reason I do not like remote mounted oil filters, if you retain the stock oil filter position just off the side of the block, it will be in the best position for the anti drive back valve to keep the cooler and lines full of oil during long engine off periods. Then when you start the engine the pump doesn't have to refill all the lines and cooler before the engine bearings see oil pressure. Makes a HUGE difference to cold start wear and tear, and is just "good practice". Oil filter maker's sites will show if a particular filter has an anti drain back valve, or with a bit of experience you can look down the threaded mounting hole and see in many cases.

In addition to what Chris has said, if you mount it the right way up, you can also pre-fill the cooler when you first fit it... rather then spinning it over on the key for ages.

I will probly just try and mount it with the fittings at the top then

Exactly what Chris said. Had a TVR years ago which came with the remote filter mounted fittings at the bottom and sure enough it took a while for the oil light to go out on starting. After I made a bracket and turned it up the other way, no problems, instant oil pressure. Plus it made for less spillage when changing the filter

With that in mind Chris, would an oil cooler really be necessary on a single turbo converted car?

For road usage with the stock Modine unit, and no FMIC blocking a stock rad, probably not in the UK. For regular track usage (track, not drag), probably a good idea to have an oil to air heat exchanger.

Chris, do you know if the K&N Oil filters have anti drain back valve?
