flybywire Posted June 18, 2014 Share Posted June 18, 2014 I am going to be towing a caravan with my Legacy 3.0 Spec B 2006. I would like to fit an Automatic transmission Oil cooler. Has anyone done this job and has anyone recommendations for a model and where it can be purchased? The Hayden brand appears on a search from Google but appears to be only available from america. Any brands, companies in the UK recommended? Quote Link to comment Share on other sites More sharing options...
Tlag Posted June 19, 2014 Share Posted June 19, 2014 I would say that's a wise choice, fitting a cooler. I don't know of any makes but I'll have a look around. 1 Quote Link to comment Share on other sites More sharing options...
Gambit Posted June 19, 2014 Share Posted June 19, 2014 Always a wise idea if you ask me :) But not sure myself where you can get one sorry :( Quote Link to comment Share on other sites More sharing options...
flybywire Posted June 27, 2014 Author Share Posted June 27, 2014 Transmission cooler fitted. I ended up using a Mishimoto universal cooler ordered from a firm in Worcester - ordered one day arrived the next morning for £50.00. I mounted it next to the power steering cooler at the front of the air con radiator. Run the two rubber pipes (i needed an extra 1 metre 3/8" length and a barbed pipe connector) to the Automatic oil filter behind the Battery. Disconnect the top pipe and attach the cooler to the rigid pipe and the pipe going to the filter. Top up with fluid as required. For extra effect I purchased two 92mm computer fans from Maplins which I mounted on the cooler. These I linked to the two main fans at the control box which can be found underneath the air intake.

flybywire Posted June 28, 2014 Author Share Posted June 28, 2014 Should have taken some I know. Will take some and post. Interesting to note that just by the 'feel test' that, with the fans operating, the outlet pipe is cooler than the inlet. Time will tell if it actually makes a difference.

flybywire Posted July 1, 2014 Author Share Posted July 1, 2014 Found it too difficult to get any decent photos but did do some readings using the wireless OBD11 - Towing the caravan results in a rise in water temperature of between 8-10 degrees for the same speed and RPM - I used 60 MPH as the base speed. Increasing RPM but travelling at same speed (changing gear) results in a 2 degree difference overall. Driving without caravan the temperature is around 89 C with caravan towed around 97 - 101. Would have liked to have done the same exercise with the ATF oil but the OBD reader does not allow me access to the data. Am interested to see such a rise in temperature with the heavy load bearing in mind that the RPM is no different. Anyone got the physics on this? Interestingly enough, the temperature gauge in the car does not alter at all! Quote Link to comment Share on other sites More sharing options...
