Hey guys, I'm going to a car radiator for my buggy, and I don't know what to do with the oil cooler water return line, and the small return line from the thermostat... Do you plumb them into the main return line? Thank you!

If you can find a service manual for the bike you have, that would be the best place to find the plumbing layout.

It seems like I've seen a pages somewhere on this site that had a listing of all sorts of bike manuals in PDF form.

Does the thermostat have more than one line out? The RX1 sled engine in my car has a setup that circulates coolant through the engine until it reaches 160 and then the thermostat opens up and allows the fluid to run through the radiator. There is a 1/4 nipple on the lower side of the thermostat that is used for the recirculation - could yours be similar in setup?

How about a drawing of some sort that shows what you have? It's pretty hard to go off of just a quick description.

Your bike has both an oil cooler and a radiator, correct - or is it a oil to water transfer system where the water circulates through the oil cooler? - if so, then yes, just plumb in to the return line of the radiator.

Yes, there is a small hose from the backside of the thermostat. It goes to the radiator. There is also a heat transfer cylinder that cools the oil. This liquid also goes to the radiator. The new radiator has a suction and a return line. I have a service manual.
