My '95 LS is missing it's oil cooler, which was a casualty of an engine swap just before I obtained it. I have one on my old '91 RS that is a parts vehicle now.Are the oil coolers pretty much the same between Gen I and Gen II? How important to everyday use is the cooler? I'm pretty sure that the block that was swapped into my truck was different(it was a 2000 model block)in regards to some accessories.I had to rig the oil pressure sending unit to make it work again,etc.Any information and experience is appreciated!
