it helped mine 'some'......until it went out...I replaced the broken with a FlowKooler...which works about the same as the old did with this modification I had made several modifications , like adding in correct fillers , one missing rubber filler below , adding X plates,....removing an electric help pusher fan that prev owner installed (blocked more air), water pump mod.,making carb run a bit less lean, ...but biggest temp change was from new 3 core alum radiator. I started with a 'normal' running temp at 220-230F...now its 185-190F
