Well I need a new fan for the engine. Nevermind how that happened. Anyways it has a small electric fan as well on the right side of the radiator. The question is, should I replace the fan with a junkyard part or should i bother trying to put in some sort of aftermarket fan for increased cooling. I'm planning on rockcrawling so it won't be getting much air flow from speed. Also, will the electric fan obstruct the air flow of the mechanical fan since it pulls less air?
