They are of furnace brazed construction and mounted to an engine that produces high amounts of vibration almost bang inline with the centre line of the rotating assembly that creates the vibration exposing them to high amounts of vibration.Do I need to mention vibration again?I agree, once my warranty is up it will be PWR heat exchanger mounted up near the gearbox, on the CHASSIS.....

Ran Transmax Z too which is what I run now in my ZF..Iv decided to build a kit basically the same as the Serious Performance Kit BUT with 1/2" lines and tanks, up from the 10mm that they run, for extra flow..It will also have a 10" fan and a Davies Craig Digital fan controller set to about 93deg.. The controller is a dual curcuit too so will also use it to run another fan for an oil cooler I intend to setup at the same time.. the controller runs the 2nd fan a few seconds after fan 1 is activated by the digitally selected temperature so will keep oil temps in check too..I am mounting them under the passenger seat with a custom shroud to stop unwanted debree banging up on them.. I believe the trans cooler kits from CMS are mounted in the same place..All up the cooler will be less than $500 + another $250 for the oil cooler setup so in total less than just taking care of a PWR heat exchanger which I think is overpriced too..Another trick I read somewhere is to put the car in reverse for 10-15 seconds when cold and it heats the fluid up ever so slightly or I also reckon stalling it up for 5-10 seconds will heat the fluid when cold too...With the extra clutches from the build I dont reckon I will suffer from damage or flair from being cold BUT I will have the insurance of it keeping cool during stall ups at the drags and also powercruise lap style track days.. which is mainly what its being built for..This spot for a cooler works well.

I was possibly going to mount it up then if the temps got out of control add the fan later..But did I read u were using a heat exchanger too ? I wanna ditch it all together so maybe the fan for me is the go.. Edited 19/08/15 01:30 PM by GUN-808 Link to comment Share on other sites More sharing options...

No need for fan. We have 7 fords 3 are turbo. 1 Link to comment Share on other sites More sharing options...

My local dealer does not think it would be covered and if it happened to be it would be on a pro rata system and dependent on cars history and mods.

My local dealer does not think it would be covered and if it happened to be it would be on a pro rata system and dependent on cars history and mods.I am not concerned about Ford covering the warranty. The secondhand car I purchased has an extended new car warranty. I called the company and spoke to the senior claims manager about the preventive maintenance I was intending on conducting. I have an email stating that if any component fails (ie fliuds mix) and the gearbox is damaged, both the gearbox and all associated components including labour will be repaired under warranty. BUT I had to install a genuine FORD heat exchanger. I sleep well at night now. 1 Link to comment Share on other sites More sharing options...

Whether they fail from vibration, quality, whatever. It always ends badly. But clearly they are a necessary evil.So is the general consensus that the problem with oil to air is warmup period, which could be quite long depending on your climate, doing the damage.We have all still blatantly ignored the fact that exchangers are no good if your box actually needs cooling...like I said would happen. Damage happens then as well 1 Link to comment Share on other sites More sharing options...
