Lt500 cooling fan

[kinderatv]

hey i dont have a headlight on my zilla. has anyone ever tried to put a 12v cooling fan to the headlight wire on a lt500 in front or behind the radiator to help cool the beast down a bit? bad idea or good?

I used one when I lived in Texas. My 88 would overheat on occassion so I installed the fan from an Eliminator 250. It worked absolutely awesome at keeping the temps down. I used the highbeam lead rather than completely eliminate my headlight. That way I could run the fan during the day and still have my light for night riding.

I never had a problem with drawing too much load from the stator and the fan worked great for the 2 years I used it.

i been having problems keeping my 88 zilla cool, been thinking about buying a cool head cylinder head for it but does it help alot or am i better off rigging up a fan on it like u guy's did?

So this eliminator 250 has basically a fan and you mounted it on the front of your radiator? correct?

[Kane]

Yeah, but reverse the wiring so that the air is blown into the radiator rather than pulling air like it normally does. It doesnt work as great in reverse with the blades being designed to pull air rather than push but it still ran mine cooler than without it. I put my fan on the lower half of the radiator since it's not a good free-flow area.

I've never run a coolhead on a zilla so I can't say how great it works.

The best cooling I ever got was on an 87 I bought that had no front hood. It never overheated until I bought the hood. But thats no solution, the zilla's one ugly machine without a hood.

heh the fan idea and a coolhead would probably be really nice then

Dig this, I've actually seen a zilla with about 4 feet of twisted-to-fit baseboard heating finned pipe used as inline coolers. It was the ugliest crap I've ever seen but it DID actually work. The guy was so sick of his quad overheating and didnt have the cash to buy the right stuff so he just slapped that stuff in there.

would air scoops help? i seen air scoops on a couple predator 500's and orther atv's to pull more air into the radiator, but do they make scoops for quadzilla's?

[Kane]

I've never seen any advertised. I'm in the process of trying to design my own. I made a couple different hood designs but didnt see any cooling temp changes. I'm thinking some small scoops deflecting air either around the motor or into the radiator would work nicely. Ive never overheated in Maine with even a stock set-up but I like the looks of shrouds.

i have a set of air scoop/schrouds on my 400ex and they seem to help, but i need something to help cool my quadzilla, its overheated on me a couple time's in the two month's ive had it, think im gonna rig up a fan on it, my buddy's got a fan off a newer suzuki eiger that he has laying around, but the only thing im worried about is drawing too much power and frying the wiring or frying the stator
