Hello, I've got a 97' D1 and I was wondering if anybody knew how many oil cooler lines there are and the best place to buy them online for the buck. I have a leak coming from somewhere, and I thought i would changed out the lines, and see if that fixed it. The other part I'm looking at replacing is the steering box. Any help would be great, thanks.

The most common leak on a DI is the valve covers, a 8mm 12 point socket will fix this.
The second most common is the oil psi sending unit, it is right above the oil filter and can be had at your local autoparts store.

 

Go pressure wash your engine and find what is leaking before you spend bucks on replacing parts that may not be needed.

 

X2 on this. I did this and discovered I have leaks in the upper cooler line and the pan gasket.

 

When i was under the Disco this morning, i was trying to figure out how many different oil coolers lines there are, so far I see a least 3-4, two which go back towards the transmission, and one that makes a loop around from the top to bottom portion of the driver side radiator. Any others that I might be missing?

 

Have you tried looking in the rave? If you don't have the rave there is a link in my sig. Try that. I am not sure how many there are. Good luck.

 

Great, I will definitely look into the Rave, I have the rave for disco 1 on my desktop, guess i know what i am doing tonight, neglecting school work in order to find what hoses are leaking on the Rave Oh how I love my Disco

 

I think there are only two "oil" cooler lines on the passenger side, front of the engine--an upper and a lower. There are two lines the make the loop from the transmission to the radiator to cool he transmission fluid. I think that is it.

I also had leaks coming from the transmission cooler lines, and had them replaced. You may also have leaks there, but you may need to wash the underside to be sure.

 

There is a engine oil cooler, it is located right infront of the radiator, on the bottom, it is round with fins.
Look trough the bottom of the grill and you will see it.

The trans oil cooler lines run INTO the radiator.

 

Cool, thanks for the help guys, I found a nice layout on www.roversnorth.com, there are three lines that are leaking on mine, the two transmission lines and the cooler to cooler line on the right side of the radiator.
