TheRecklessEngineer Posted April 28, 2009 Share Posted April 28, 2009 Do remember that the oil cooler is an oil/water cooler - the oil will never drop below the water temperature. IMO, having the cooler will have negligible effect on the viscosity of the oil. Quote Link to comment Share on other sites More sharing options...
Aragorn Posted April 28, 2009 Share Posted April 28, 2009 well it has done... because now his oil pressure is higher.... It may well be a water to oil cooler, but theres nothing to say that the water in the radiator is at 90c, the engines thermostat will keep the coolant temperature INSIDE the engine at 90c, but its perfectly feasible when driving at high speed with low load, that the average water temp in the rad could drop a reasonable amount below this... The rads designed to cool the engine when its producing 120hp, and when crusing along a motorway you'l be lucky to be using 30hp. the difference between oil at 70c and the same oil at 90 will be easily measurable, so its not like your talking infinitesimal differences in viscosity either Quote Link to comment Share on other sites More sharing options...
jacks906 Posted April 29, 2009 Share Posted April 29, 2009 sorry to go back to it but this oil stat you talk of are you getting it mixed up with a oil relief valve as in if the filter gets blocked that passage way opens to allow the oil to get passed so that there is no oil starvation???? dave Quote Link to comment Share on other sites More sharing options...

It deffinetly acts like a coolant thermostat - it expands out and contracts in with the heat changes and has a spring and two big washers on it. Are we taliking about the same thing. The issue is now resolved - we found a steel washer in the brand new oil radiator that must have been blocking the flow. I have never seen a washer of this size and type in the engine and certainly not any where near the oil plumbing so it probably got there before the part was delivered as we took it out of it's original packing when we installed.
