Cleaning the radiator

I noticed last night that my radiator had dirt caked on it. So I sprayed it as best i could from the hose and it cleaned it off fairly well. It looked to be so bad that it was almost a mud wall and I'm sure it was making the engine run hotter.

I wish it had a temp gauge.

I was trying to figure out how to remove the front so I could get at the radiator but the two bolts on the bottom and the two top plastic pins were removed and it wouldn't come out. I think the fenders were holding it on.

I know you can remove the front guards but that doesn't really help. I need to get at the BACK.

Any ideas, cleaners, etc?

I spray mine with some degreaser every now and then and it shines like new. But I also wash it down after every ride so that makes cleaning easier. The caked mud will lead to overheating and I'm suprised it hasn't yet! The best thing to do is blast it from the back forward. This is the way the mud came in and thats how it has to go out.

Pressure washer works much better than a garden hose (more pressure).
Hot water works much better than cold.

if you have a pressure washer, or can borrow one - hook the supply hose to the drain on your hot water tank in your house. Then use the hot water to steam clean the radiator - you'll be amazed at the difference.

Good Luck!

As a mudder, i always clean my rad before and after a trip. Mine is usually packed solid, but because i do not let it sit and harden it usually comes out pretty easy with just a hose.

I used pressure air with blow tip like for engines where wand is like 12" and the tip at +/- 45*, set up pressure for 40 Psi and blow it from the back.

If you use anything with any real pressure (like a pressure washer), don't get too close while blasting. The fins on the rad are super-thin and you can bend em flat with no problem.
You might want to give it a good soaking and let it sit...then repeat. Might take a while to soften up a thick pack of dried-on muck.
Once you get er clean, rob350 has the plan, rinse it out after every ride...it's that "once of prevention" thang. Colbygil also nailed it with hitting it from the back but that's a heck of a lot easier with the plastic off.

do not do this. unless a pressure washer is made for hot water

the cold water is used to cool the pump as it heats up from compressing the water.

if you run hot water, you may damage your pump

Hi; Iv'e got a 600 so I have a oil cooler to deal with the same princeable, I ride in the mud 90% of the time with our club and on serveral poker runs each year and I came along a neat trick. Clean your radiator and or oil cooler then before you ride in the mud spray it down front to back with, ( WAIT FOR IT.... PAM,) yes pam it covers the metal with a light film and won't burn off fast. This sounds crazy but it works for me rideing here in the N.W. WA. GOOD LUCK, GREASY.
