First look for a spot where it can be fit in. Then buy one that will fit.

It does not have to be in front of the radiator. You can mount one under the bed in the back away from the muffler. If the oil runs over 220 degress when pulling a heavy load put a small 12 volt fan on it. The cooler the oil is the longer the additives in it lasts.

Have a good one..  Don S..

A few days after I bought my 2008 crew cab Frontier whilst driving to Spokane, I noticed a smell coming into the cabin.

Being a mechanic for over 18 years I knew it was an oil smell of some sort. When the following morning I opened the hood and got down under the car ,the engine cradle was thoroughly wet with ATF oil.

I traced the leak to the cooler up on the core support and immediatley rang the dealer from where I bought it from. They even said the car was serviced with oil and filter changed, I knew by looking a the filter it had not been changed and if it had the tech should have noticed the leak?

So I let them have it on the phone and told them that if anything happens to the tranny in the future I wanted it put on record that there was a leak in the cooler and this may cause problems later???

They fitted a new cooler and doubled new hose clips on the fittings.

My 2008 frontier i just bought 2 weeks ago is in the shop right now getting a new radiator, new transmission, due to the transmission cooler leaking inside the radiator.

  The dealer said he has seen this happen before, i asked him how many? He said they only had 2 frontiers with this problem before, sounds like it's a pretty common occurence.  I sold my 2002 frontier 3.3 v-6 recently, with 118k miles, no radiator problems at all. Hmmmmmm?
