[DeTomaso] Oil cooler question

Wed Sep 12 14:24:53 EDT 2018

Maybe; maybe not. Some owners running oil coolers do not use an oil thermostat. Their success may be due to most of us not really needing an oil cooler at all. I chose to run an oil thermostat on my experimental rig so as to not cool the oil when temperatures or the conditions I'm running do not need extra-cooled oil: eg- slow driving. Note that water cooling oil WILL raise water temps (about 5F while lowering oil temps about 20F); there's only so much total capacity in the car's cooling system. I run a Fluidyne rad with extra cooling capacity & those numbers are what I got.

As far as connecting the water cooling lines of an oil-water cooler to the heater fittings on the engine, you'll have to decide if changing the water flow through the cooler to less than half that designed for by the engineers who built it, will work for you: 1-1/2" OD rad' lines vs 5/8" OD heater lines. Again, if it works, that may only prove that the cooler wasn't needed in the first place. In my case it certainly wasn't, but I wanted to see if one would lower oil temps significantly on our mostly street car.

  If the oil cooler was plumbed in series with the cabin heater lines would a thermostat even be necessary? Seems like      an effective way to get cold engine oil up to operating temperature as quickly as possible and allow minimizing of    oil cooler line length at the expense of slightly longer heater hoses.

  I have a Laminova oil cooler on the outlet of my radiator and for
  street
  use in the desert, it does a pretty good job. When I used the car on
  our
  local road course race track, oil temperatures would start getting into
  the 240 degree area. My car has a front mounted air conditioning
  condenser, so the area where the original condenser was located was
  available to install an air to air DeRalle oil cooler with its own fan
  assembly. Oil temperature is now staying around the 210 to 220 degree
  range when the car is being tracked. My engine has a Titan oil pump
  which was set up to compensate for the additional oil lines to and from
  the coolers.
  Two oil coolers may sound like overkill, but the second oil cooler
  which
  is now in the rear of the car was actually very easy to install. The
  rear cooler fan has a thermostatic switch which doesn't come on until
  the oil reaches 180 degrees, which in turn doesn't allow the oil to be
  too cold. High horse power engines generate lots of heat and cooling
  the
  oil also helps to keep the water temperature down.
