I have a 2.1 dj that i'm going to replace my 1.9 with, this has an 'oil cooler' between the oil filter and the block, can i remove this and run it the same as my old engine and if so which parts do i need to interchange.
you would be advised to keep the oil cooler, and add the extra peice of water pipe........ but the answer to your question, is yes, you can, just unscrew it. i wouldnt tho
as long as you keep the 2.1 water pump, yes, just "t" in for the outlet, which shouldnt be hard, presuming you have the metal shaped pipes from the oil cooler still on the 2.1 .
It does both. It heats the oil using the water when the engine is cold and cools the oil using the water when the engine is at running temperature, when the water is cooler than the oil.
PM'd yer Shep..
It may help with warming a bit, but it does help oil temps when hot, but it doesnt control the oil temps in hard worked situations.. something to be aware of if you drive hard or are in hotter climates...
