My buddy had a stick wedged in between his radiator and his fan which prevented his fan from running. His 650 overheated and when it did, the plastic on the fan got so hot that, combined with the pressure of the fan motor attempting to spin the fan, the plastic fan melted right off the motor spindle/axle (whatever you call it).

He dropped his 650 off for its 1st service yesterday and may end up paying for it (not under warranty) b/c of the stick. I think I remember a post where someone had to replace the ENTIRE fan assembly, including motor b/c Kawasaki doesn't sell the individual parts (i.e. just the fan blade only). If I remember correctly the entire assembly as in the $250-$300 range.

Am I correct in remembering this? Can you order the fan blade only? If he can't...is there somewhere we can contact that may have them, atv salvage yard, or some other after market place?

As always...thanks

 

parker..this is off your subject alittle ,but does your fan run alot..mine seems to run nearly all the time once the quad is wrmed up.

 

Metallikev-- Do you clean the backside of the radiator? I gets plenty muddy. I ALMOST learned this the hard way, when the bike was new to me.

 

Yeah Parker, you have to get the whole assembly and it was about 280 or so. I forgot who said it, but they had to buy the motor and fan assembly (even though they only broke a blade).

I suggest trying to use the 8" permacool fan, since it is probably less than $100 (but I would only suggest this if he has the tools and skills to fabricate whatever moutning brakets).

I'm not sure it would fit, I just think it could be done. It is the route I would take if I broke my fan. It would probably blow more air too.

Another thing, other people have been suggesting going to a motorcycle junkyard to get a used fan.

 

Thanks for the info, Nyroc. Thats what I thought we'd have to do.

Metallikev: I replaced my oil (with 20w-50 Mobil 1 V-Twin) and coolant (with 75% water/25% anti-freeze with 2 ounces of moto cool additive)last week. I also cleaned the radiator thoroughly. We ran them HARD this past weekend. 121 miles of 55 mph+ speeds for 10-15 minutes at a time. The fan probably ran over 50% less than it did before. When I'd shut the machine off after getting on the throttle hard, the fan would run for 45 seconds to a minute then shut off and not come back on. Definately an improvement.

I suggest using a garden hose w/ no nozzle, get right up to the radiator front and back and soak it thoroughly. Turn the hose on ALL THE WAY. After you have got it good and soaked (5 mins or so), put your thumb over the end of the nozzle as hard as you can to create a spray and put the spray right up against the radiator, front and back. You'll be amazed at the gunk that will continue to come out of the radiator. Do this for at least 15 minutes. you will continue to see mud come out.

 

Thanks Parker,Ill give it a try when the missus get home. I have not cleaned the radiator yet and maybe that is the issue,although i have not tested the coolant mixture(I will today)Im not sure if the dealer or kawi puts the mix in..but Ill give it a check and replace if need be..we going to the thousand Islands next week to ride the rivergate trail and It will most likely be hot..I want no problems.

 

Parker/ et al --- I cut holes in the LF Inner fender just for cleaning the back of the radiator. I found some plastic "blanking" plugs, that I just pop out. I turn the wheels full lock left, pop 2 plugs, and have at it with the garden hose....it works for me. The inner fenders(frt) have a bulge in them, outlining the radiator tanks. The bulge will tell you where to place the hole if you care to use my idea. I think you can buy the plugs at Radio-Shack. I found mine at work.
