Upgraded trans cooler Question?

I have upgraded my Auto trans cooler in my GT forester. The new one is now about 4 or 5 times bigger than the factory one. I have removed the factory one and now have the larger one in its place.

Just one questions... should i change the hoses so that the auto fluide no longer runs through the radiator or leave it as it is?

I realise the radiator serves to also warm up the fluide but i don't know if this is needed in Australias climate and if there could be an added cooling benfit by bypassing it.

leave it davo

also... if u still do a lot of boggy sand work with the car going slow, put a small fan on it...benefited my outback when i had it....kept it all coolish still under high load and low speed

mine is bypassed. it takes noticeably longer than stock to come up to temp (wont lock the torque converter until it warms up so its noticeable) but i figure im trying to keep the thing cool, so i put up with it taking a bit longer to warm up.

where have you located it??

in the old suzuki sierra rally car we had, the oil cooler was hidden behind the numberplate apparently cars that looked highly modified were attacked (by authorites) and an oilcooler was considered one of the big give aways.
when the temp was up you just got out and moved the number plate

I got it directly behind the front grill. High enough that it gets the full benfit of the cool air and it's spaced a few inches from the radiator.

Don't have to worry about police with this car mate... made everything legal and neat so thats no problem.

Good stuff. I'm trying to do the same with Ruby Scoo - standard offset rims are going to make a HUGE difference if I can get any, either with the crossbred conversion kit or not...

I don't think it would hurt to leave the pipes to the radiator connected but usually they're not used when a new aftermarket oil cooler is installed - at least that's what I've seen with just about all applications...

For towing or long trips you could hook it up with a tap in line to feed either to the radiator or the aftermarket unit - this way you can have the best of both worlds for the given situation if you want... Dunno if it will actually work but it could be worth looking into.

Nice idea, but don't forget the old KISS principle, Bennie.

My mechanic advised disconnecting the in-radiator cooler when I put a big aftermarket trans cooler on the Fairmont. Being too cold is never likely to be an issue, and a good aftermarket cooler is usually much more reliable than the std one, and won't damage your trans and cooling systems all at once if it springs a leak.
