i am replacing my buddys oil cooler hose on his 2003 330 magnum. i ordered a replacement hose through ronnies. it arrived and i noticed that only one end (the end that goes into the motor) has a connector on it the other end has nothing. i was wondering if anyone knows if i can use the old one that i am taking off of the quad to connect it to the cooler. are these ends threaded or do they have to be crimped on? any help would be appreciated, thanks.

 

The newset 330s have threaded connectors at both ends finally. The older 330s and all 325s are threaded at the engine and barbed fittings at the cooler. All 325s should been updated to threaded fittings at the engine.
Use of 0W-40 oil is highly recommended to prevent blowing off the hose at the cooler because of the high pressures the oil pump puts out on the models with the barbed fittings.
