Author Topic:   keeping radiator clean
posted August 03, 2003 08:18 PM
Was hoping someone could give some advice on how to keep our radiator clean during a night of racing. I take it out & clean it every week, but by feature time, it's filled with mud again. I've tried window screen,(keeps it clean but lets no air through), & this week ran 1/4" hail screen horizontally from rad. to front of car, & it was filled after the heat race. We run on gas,(limited mod class), so keeping the rad. clean is very important. Any help would be greatly appreciated. Thanks.

i run 3 layers of screen 1/4 ,1/8 and window make sure you mount it a little in front of the radiator so it can move when the mud hits it and the layers will break it up better so if it does stick it's smaller chenks you can also spray it down with some mud off or baby oil so it doesn't stick as bad

Lots of Mud-Off or baby oil all over the screen and the radiator worked well for us last night. Dont forget to get the crossmember in the front so it doesnt pile up in front of the screen.

Mount some aluminum in front of the radiator to block the bottom 1/3. Leave some space between the radiator and the aluminum. I usually mount it on or against the cross member. I run in Central California where the temperature is 95-104 degrees in the summer and the track is extremely hooked up and throwing mud all night long (guys run out of tearoffs). The aluminum doesn't make the car run hot, and keeps the majority of mud from plugging the radiator. Also, it's easily removeable in a hurry.

If you try more screen, use a shroud of some sorts to help pull the air through the radiator.

On mine the nose piece blocks the direct path going to the radiator and the air is pulled from the ground. About 4" in front of the radiator I have an eighth inch piece of aluminum that blocks the bottom one fourth of the radiator. I do not run any screen. The nose piece has sides and there is a shroud. I do not have any problems with mud blinding the radiator.
