Is anyone running an oil cooler. Driving around on a hot day today and my aux was working hard to keep temps down (supercharged by the way). Is there a standard place to mount them on mokes?

I did have one at one stage (very log ago) on the wife's Moke. I made a bracket that mounted to the front rail of the subframe and lifted it about 2" so it was in the air stream coming through the grill.

 

As far as temps went, it made zero difference, and after about a year, it started to leak (despite being new), so I removed it and never bothered with one on a Moke since.

 

Is it actually running hot or is it just warm due to the high ambient temps?

The heat goes up considerably when I give it some beans. On a hot or cold day and the fan kicks in.

Im interested in this too, since mine is about tobe supercharged. Was looking at the MED kit.

My supercharged mini has an oil cooler, I just put that on as a matter of course. I think its best to put a smaller one on if any, like 11 row

Just keep in mid guys that roughly 1/3 of the engine power is dumped in to the cooling system, and that's on an engine with a clean cooling system and that is running in correct tune, in particular, ignition requirements.

 

So, the more power you drive with, the more heat going in to the cooling system that needs to be dispersed.

 

Also, with the volume of Oil held in a Mini / Moke sump and the rate at which it's pumped around, you really do need to be making a lot of power all the time to warrant an Oil Cooler. Oil is very slow to accept heat (compared to water and coolant) and equally, when hot, is slow to disperse that heat. Putting this in terms of a road car, you need to be on the loud pedal for a fair while fairly constant (5 - 10 min) to get engine heat in to the Oil in the first place.

 

I'm not sure if you guys have a By-pass connected, but that's one of the first things to block off. Apart from early onset of cavitation, they only take hot coolant from the head, bu-pass the radiator, and dump it back in the block.

then look to your cooling system.

 

an oil cooler if fitted should be fitted with a thermostat as there is nothing worse than cold oil.

If you fit an oil cooler without a thermostat you're are cooling the oil from the moment you start the engine.

to be honest every supercharged application I've had ran hot, but for my desert rat that only gets driven on sunny days, it needs all the help it can get. The current cooling is pretty standard apart from minispares 2 core comp rad, expansion tank and extra fan. I've got a sump guard on too. So if there's any suggestions. I would only put a thermostat on with the cooler.

Oil coolers really are only any good at cooling oil  O_O

 

That's a bit of a glib statement, but still true. The waterways in your engine are positioned to collect heat where it's generated, mostly the cylinder head. The oil feed there is to lube your rockers and can maintain pressure fed through a drilling of what -1/8 inch?

 

I run a cooler but I have a turbo that has only oil running through it.

What about having an extra rad at the front?

If you have room for a front mount rad do away with the side mount.

Run them both!

 

I did once try 2 radiators, the stock one + a full size Mini one as a front mount. Cosy and as it turned out was pointless, but fitted.

 

 

The stock system will cope with power levels up to around 90 - 100 HP, but that also depends on how it's driven too.

 

If your set up isn't coping, and your actual power output is less than this (what you are generally using, not what the engine is capable of) then I'd suggest there's another issue that needs looking in to.
