Oil getting too hot can be the death of an engine.  Enter, the oil cooler.  I had seen many sandwich plate oil coolers and actually purchased one but was disappointed by the fact that I could not find one with both a port for an oil temp gauge and a thermostat that would fit my Vortec LS engine.

I somehow found www.improvedracing.com while searching around the internet and gave them a call.  I don’t remember what my original question was, but boy did I get lucky!  They sell an oil cooler plate that covers the 2 holes above the oil filter on an LS engine!  I was completely floored when the guy told me it was thermostatically controlled and had a port for a gauge!

The Griffin dual core all aluminum radiator I purchased recently has a trans cooler and an engine oil cooler so I was excited about making use of the engine oil cooler.  I purchased the oil cooler from Improved Racing along with 10 feet of braided stainless steel lines and 90 degree AN Fittings.  I was set!

If you are going to make your own lines (put the AN fittings on the stainless-steel lines), do yourself a favor and get the AN fitting holder for your bench vice.  I don’t know how you could make the lines without it.  I mean, you could, but I think I would totally scratch up those pretty AN fittings.  With the tool, it was very easy.

I hooked up the lines to the plate and then affixed everything to the engine block.  The lines run from the plate, straight forward (via 90 degree AN fittings) to the top and bottom of the driver’s side of the radiator.  If you don’t have an engine oil cooler built in your radiator, you can get an exterior cooler on eBay for cheap.  Just make sure you pull your front grill and measure to make sure it will fit somewhere on the front of the AC condenser.

Installation is difficult only because of some of the contortionist positions you need to get into to get the plate on the side of the block.  If you have 4wd, you will also need to unbolt and drop your front drive shaft (don’t forget to mark it!).  Also, if you run wiring for a gauge, run it forward so it doesn’t get chopped up by a front drive shaft, or burnt by the exhaust pipe.
