I was just curious on which years of Disco's got an engine oil cooler. I've never found one on my 01 so I was just wondering which ones did get one.

 

99-02 should all have an oil cooler. 03-04's don't. Remove upper fan shroud and look down you should have 2 coolers stacked on top of each other. One for the transmission and one for the engine oil.

 

It's in front of the radiator on the 99-02. When I say I'm the front, I mean closest to the grill. One is for the transmission and the other for engine oil.

 

Well I was convinced that I didn't have an oil cooler, but I removed the upper fan shroud and there it was. I've had the shroud off before, but never thought of looking for it. Thanks for showing me where it was.

 

No problem at all.

 

I had a customer who has an '02. Don't know where it falls in production during the model year but he most definitely did not have an oil cooler. He was a mechanic who works on exotic European cars and bought the truck for his daughter. We spoke just the other day about an oil leak around the front cover and when I looked at the cover the hole that would normally accommodate the oil cooler line was blocked off just as it is on the '03/'04 models.

I don't know if they stopped installing the coolers towards the end of the model year or what but everything looked like it came that way from the factory.
