how do you flush a radiator. can you just run water through it or is there a chemical you can use, my laser has the dirtiest radiator and keeps over heating, wanna do it my self as it is only a thrash car.

cheers patts

You can pull the radiator out and flush it under reasonably high preasure from the bottom- Up.

Re fit the radiator and you can get some additive thats supposed to loosen all the crap inside it. run that for a few days and reflush it..

Should be then like new

cheers mate i think ill just fluush it and thn thrash it buy stuff just doenst agree with me

it's not supposed to flush for a few days, but a few good hours will help.

Read the instructions, and make up your own mind.
