logic23 Posted August 8, 2010 Share Posted August 8, 2010 Does anyone know why only forester engines have the water cooled oil coolers? Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted August 8, 2010 Share Posted August 8, 2010 Hm not sure, actually I didn't know they came with them. I know the H6's have that setup. Must be in the Forester they saw the need to buffer the oil temp against the coolant temp. Quote Link to comment Share on other sites More sharing options...

porcupine73 Posted August 8, 2010 Share Posted August 8, 2010 Ah ok maybe part of a towing package...hm some research on cars101.com might show it. Quote Link to comment Share on other sites More sharing options...
logic23 Posted August 8, 2010 Author Share Posted August 8, 2010 I dont think it was a package thing. Every forester 98+ i've worked on has them. I've been adding them to the engines I rebuild for added longevity. The have aluminum thermostat housings with an added snout > hose runs to oil filter area where the cooler bolts where oil filter goes with a longer tube. the cooler has two snouts: one to the thermostat housing one to a snout that threads into a water jacket that has a 14mm allen plug. unthread plug then thread in snout and voila>>> oil cooler Quote Link to comment Share on other sites More sharing options...
ferret Posted August 8, 2010 Share Posted August 8, 2010 Automatic and Turbo Foresters have them. N/A 5 speeds did not. Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted August 8, 2010 Share Posted August 8, 2010 '91 Turbo Legacy's had them as well (but later years did not). They only came as a 5 speed. It was initially a turbo thing - Forester's probably got them for light towing. Frankly I would rather have a real oil cooler rather than one that is tied to coolant temp. Not an ideal system IMO. Better than nothing though. GD Quote Link to comment Share on other sites More sharing options...
CNY_Dave Posted August 9, 2010 Share Posted August 9, 2010 It might also be there to *heat* the oil in cold climate areas, to prevent sludging. Dave Quote Link to comment Share on other sites More sharing options...
johnceggleston Posted August 9, 2010 Share Posted August 9, 2010 i looked at the opposedforces.com/parts parts site for forester SOHC engines and it indicates that the auto trans got them and the manual trans did not. Quote Link to comment Share on other sites More sharing options...
porcupine73 Posted August 9, 2010 Share Posted August 9, 2010 That's true. I think that type of oil cooler/warmer is great if the vehicle is being used for a lot of short trips to help the engine oil get up to around 180F faster to avoid condensation build up.
