+====== Why Use an Oil Cooler? ======
+One thing to remember is the temp reading at the oil tank and the actual highest oil temp in the engine are not the same things. ((Graywolf of the XLFORUM http://xlforum.net/forums/showthread.php?t=611969&page=9)) \\
+It depends where the reading is taken. \\
+Oil coolers may not be needed in cooler climate. The engine is not only air cooled, it is also oil cooled. ((Graywolf of the XLFORUM http://xlforum.net/forums/showthread.php?t=611969&page=9)) \\
+The oil circulation carries a lot of the internal engine heat away. Engines are built to run certain specs. \\
+Operating temperature has an effect on the specs due to heat expansion of the metal. \\
+Minor point maybe, but the engines are not built to different specs to be sold in different climates. \\
+We run different oil weights for different climates. The closer you stay to the ideal operating temp, the easier it will be on the engine. \\
+It will also slow the oil breakdown. \\
+People argue either way on the benefit of an oil cooler. ((Graywolf of the XLFORUM http://xlforum.net/forums/showthread.php?t=611969&page=9)) \\
+However, the reasoning for using an cooler ranges from: \\
+Larger oil capacity, lower oil temp and better engine cooling in summer (especially in high temp climates). \\
+You will have to make your own decision on when to use an oil cooler. \\
+Sometimes it just boils down to piece of mind.
+But using one can't hurt the engine. \\
+====== Installing an Oil Cooler ======
+Do not pull hoses too tight or oil flow restrictions can occur. \\
+===== Hose Routing =====
+Hoses must be routed so they do not contact or interfere with any hot or moving parts. \\
+Hoses must be routed above the bottom of the frame tube to prevent hose damage if the frame should contact the pavement or a highway obstacle. \\
