Gregg Says: It will have 2 lines going into the radiator on the driver's side.3. me Says: if its an automatic ur talkin about, u should have oil cooler lines. Anyway. Look at ur radiator. There should be 4 metal lines coming out of the radiator. If 2 of em are ur tranny cooler lines. An "in" from the tranny and an "out" to the tranny just follw where the lines go. And the other 2 should be ur oil cooler lines. Which should lead to the engine block. Fyi sometimes people crimp the lines off but u can always tell by looking at the radiator side of the oil cooler lines cuz the in and outs on the radiator will be crimped as well. Godd luck. :)4. mdk68gto, ase certified m tech Says: look at the base of the oil filter for the adapter with two lines coming off of that. if you see that much, then it has a cooler.5. Two Lane.
