Found out that my 2005 Pathfinder with 165000 miles on it was spotting the driveway with oil.Degreased the area around the oil filter and determined that the gasket between the oil cooler and block was leaking.For those having to do this, it's pretty easy.Remove the splashshield and the oil filter cooler is staring you in the face. No need to remove coolant hoses as there is plenty of slack. Cooler unbolts with a 22mm socket that is torqued to 36 ft/lbs. Gasket costs $14 at the dealer.The old gasket had taken quite a set and was about 3mm thinner than the replacement. Even after oiling both sides of the new gasket, the fit was snug in the oil cooler giving no worry about slipping out of place during reinstallation.You can get Nissan OEM gaskets off of ebay for around $7 delivered but I wanted the car back in service today. First of all, thanks the OP and this thread I fixed the annoying oil leak in my 2009 Pathy. My experience was a little different and I figured I'd update the thread with something else to look out for.
The Nissan Titan has never been the most capable truck on the road, but with Nissan reliability and a 5.6-liter, V-8 engine, it is a nice alternative to the 'Big Three' truck manufacturers. In order to make the most out of the quality craftsmanship of your 2014 Titan, it is best to keep the fluids topped off. Automatic transmissions in certain 2005-2010 Nissan SUVs and Trucks are under attack from their radiators. Leaking coolant is mixing with transmission fluid through the cooler lines to create a toxic hell stew that irreversibly damages everything around it.
I assumed my cooler o-ring was bad so I looked up the part and bought oil, filter, gasket, and a 22mm socket. When I got in there, I realized that AutoZone had given me the 3.5L version of the gasket. But, the original gasket was still good - the cooler assembly was just super loose, I'm assuming from removal of a tight filter during a previous oil change. I cleaned everything up and put it back together (since I didn't have another vehicle to get the right gasket), and voila!
No more mess under the Pathfinder.
(more below:)(855) 882-2955 (toll free)Nissan transmission/radiator failures can and do happen.This is where we see Nissan transmission cooler tanks break inside the radiator. The type of failure allows automatic transmission fluid and engine coolant to mix.When running, the pressure in the transmission cooler is greater than the radiator. This allows transmission fluid to enter the engine coolant in the radiator.When the engine is warm and not running, the pressure in the cooling system is greater than the transmission and allows engine coolant to enter the transmission fluid. Eventually, the transmission fluid will turn anywhere from a 'strawberry milkshake' color, to a chocolate brown, depending on the condition and age of the fluid.We have a patented Gly-Tek glycol test that can detect concentrations of coolant in the transmission fluid as low as 50 PPM (parts per million). This test is only $80 and can save you THOUSANDS down the road.
