How to Install the Derale Plate-Fin Engine Oil Cooler Inline with another Oil Cooler  


I have purchased a D15405 oil cooler kit and want to add it to the existing oil cooler on my 97foot 36 foot motor home with a water type oil cooler already on it. can I use both oil coolers together to keep the oil temp down since the engine only has a 6 quart oil capacity. Also I use the 10w 30 Joe Gibbs oil.


Expert Reply:

That depends on the size of the hose that is used to install your current oil cooler. If the line is the same as what comes with the # D15405 that you purchased all you would need is 2 sets of the # D13024 so that you could install the cooler inline with your current cooler.

You would need to thread each set of the fittings together and tighten them down so that you would have two male end fittings. From there you would need to cut your current oil cooler hose and install the # D13024 inline using the fittings as a way to splice the cooler inline so that the oil goes through both coolers before it returns to your engine.
