Hi to all.

I have an inquire about oil coolers, I bought a 2007 Ford ranger auto 3lt turbo, oil cooler fitted, At that time I was pulling a 17ft pop top light weight van,

We have now up graded to a full van 22ft 2.5t, It has been suggested that I fit another oil cooler for extra protection, Even though at no stage has the gear box been hot.

I am hopping some one will have some information that may help.

Regards Bowser.

Hi Bowser

Never been hot?, so you have a temp gauge on your transmission. What temps are you running at now? Do you need another cooler will only be found out if you know your current temps, I dont think the difference in van size and configuration will make too much difference but the way you drive will.

cheers

Bowser,
The best advice is usually given by a transmission specialist, they will know what you need, and I'm betting you don't need an additional cooler, but you may need a bigger one, as we found out the hard way once with our Fairlane, so I would suggest you talk to a specialist, a good dealer may have some helpful advice, but they usually only know what the factory tells them.

Our transmission specialist also rerouted the plumbing on our Falcon, to bypass the radiator, I think that's who you need to talk to.

Find a good one, maybe RAC approved?

Hi Blaze

Only going of the fact that no warning lights have come on so far, no temp gauge fitted, Might be a start.

Thanks.

 By the time the warning light comes on, the oil and transmission has already overheated. Some vehicles do not have a means to measure transmission temperature. I have a scangauge and it is programmed to display transmission temp. Some new vehicles will potentially go into limp mode or reduced power via electronics if the transmission overheats in order to minimise damage. Most of us make the mistake of putting driving lights right in front of the transmission oil cooler. Under most circumstances towing should be done in a gear that allows the torque converter to lockup, usually this is fourth. When the converter is locked, there is minimum slippage and therefore less heat. if managed correctly, you should not need an extra oil cooler. Fitting an extra oil cooler may also involve extra amount of transmission fluid.

Sound like a good start Thanks/

Hi bowser. I have a dmax ute with a scan gauge registering transmission temps. After much research I bought a Davies Craig oil cooler after Davies Craig gave me an excellent email on information. Long story short I bought mine from super heap auto and fitted it myself, I bought the biggest model I could get and the fan as well , the fan rarely comes on but I am very pleased with unit saves around 20 degrees roughly depending on speed and load etc I have no affiliation with Davies Craig or super cheap. We tow a 3 ton van so it has been a blessing. My dmax never overheated but temps were getting up around 100c. Now it usually around 80c. Regards philchook

Hi, is the cooler an aftermarket type or genuine Ford external cooler ( not built into radiator lower tank)? If it is an external or aftermarket type, and there is no air restriction from lights etc directly in front of radiator, then, you are o.k. If the cooler is in the lower radiator tank, then is essential for transmission cooling to disconnect and fit an external cooler. When you are able I would advise that you have the transmission and torque convertor drained, flushed then refilled with a pure synthetic transmission oil. When towing, it is advisable to only use fifth gear when on the level and the engine is running freely, try and keep your engine revs around 1800 - 2200 unless climbing hard, it helps the economy and the transmission.
