nik77 Posted January 14, 2018 Report Share Posted January 14, 2018 HiMy car is 2007 S60 T5 (2.4)Planning to install ATF cooler ( 16 rows Setrab) and Engine oil cooler (19 rows Setrab)Here ambient temperature is averaging 35-38 celcius.For ATF cooler, better bypass radiator or run in tandem with radiator? If bypass radiator, will Setrab 16 rows sufficient? In stop go heavy traffic jam, will ATF temperature get hotter?As for Setrab 19 rows engine oil cooler, i take away the factory liquid to liquid engine oil cooler , and replace with adapter plate...with long hoses connect to Setrab engine oil cooler. Will install the Setrab engine oil cooler at the front tyre well. Will use 7" fan as at that location no direct air flow.Unfortunately no gauges to read both ATF and engine oil coolers temperature. Hope my planned setup works fine in hot climate Thanks in advance for any reply Link to comment Share on other sites More sharing options...
Zappo Posted January 14, 2018 Report Share Posted January 14, 2018 When I had an automatic, I ran my ATF cooler in series. It was a small B&M super cooler, but it still lowered ATF temp by 40F on track days over just the stock cooler. The ATF will only really heat up with use, so sitting in traffic won't cause it to heat up. However, sitting in traffic won't allow your external cooler to do its job either, unless you put a fan on it. With the stock one in the radiator, you will at least have the fan to help cool the fluid. I also installed a filter for the ATF and a temp sensor. What fan are you using for your oil cooler? I would like to install one for my cooler as well. Link to comment Share on other sites More sharing options...
Beunhaas Posted January 14, 2018 Report Share Posted January 14, 2018 You have some pics? I just bought 6 row cooler for my atf. Link to comment Share on other sites More sharing options...
nik77 Posted January 15, 2018 Author Report Share Posted January 15, 2018 Thanks for replies Not buy the coolers and fan yet, but i attached the sample pics Afraid of coolant and ATF mixed up ...if the built in radiator cooler leak. It happened to several my friends' cars If got space, some advise to get biggest possible ATF cooler if to bypass radiator . But S60 frontal grille don't have much space. 16 rows cooler can fit. 19 rows i think cannot Anyway i use Ultragauge to monitor coolant temperature before entering radiator. After exiting radiator, I have a sensor fitted to return radiator hose and Shadow digital meter. Before entering radiator, the Ultragauge usually read between 87 to 90 celcius. After exiting radiator the Shadow digital meter usually read between 55 to 65 celcius. So from the coolant temperature reading, the built in radiator atf cooler will submerge in 55 to 65 celcius coolant. I understand while stationary in traffic jam the ATF temperature didn't get high. But what about crawling and stop-go traffic that frequently change between 1st to 2nd gear...will ATF temperature rise? Thank you guys The ATF and oil cooler. It's stacked plate and fin design. I read, this design is the best compared to tube&fin and normal plate&fin Stacked plate and fin are common to Setrab, Mocal, Mishimoto, B&M...just to name a few The 7" fan for remote mounted 19 rows engine oil cooler... Will take away the factory engine oil cooler... Link to comment Share on other sites More sharing options...
Zappo Posted January 15, 2018 Report Share Posted January 15, 2018 It is all about the load on the fluid. Heavy traffic isn't going to do it as you aren't putting any stress on the transmission. High speed, frequent heavy acceleration, climbing hills and towing; those will cause the temps to get high. Link to comment Share on other sites More sharing options...
nik77 Posted January 15, 2018 Author Report Share Posted January 15, 2018 And fit the adapter plate like the sample pic...and connect to remote mount 19 row engine oil cooler... Just now, Zappo said: It is all about the load on the fluid. Heavy traffic isn't going to do it as you aren't putting any stress on the transmission.

Maybe the ATF temperature get much hotter too I did some serious street racing before and the coolant temperature highest recorded was 102 celsius Link to comment Share on other sites More sharing options...
neilv Posted January 17, 2018 Report Share Posted January 17, 2018 The diesel oil cooler (D5) in Europe is twice the size and mounts exactly like stock. Engine warms up quicker and stays at operating temp better. Also have you tried running 60/40 coolant mixture vs 50/50. if you don't see -20 or close to it then you should be just fine. Maybe 70/30 depending on your climate. Maybe even a water wetter too. We get up to 30/33ish in the summer here and with 60/40 an the D5 cooler on a modded K24 2.3 I never had the coolant gauge budge even with hard driving Link to comment Share on other sites More sharing options...
nik77 Posted January 21, 2018 Author Report Share Posted January 21, 2018 I use 2 litres of coolant and water wetter Link to comment Share on other sites More sharing options...
