Best coolant flush?

Rice · Nov 28, 2012

Hi, going to replace the thermostat and coolant on my discovery, just want to know what to use to flush out the system, preferably cheap! Such as I've heard of washing up powder being used, or a dish washer tablet... Anything better?

Don't think there's any crap in there, cools itself fine, well, a little too well to be honest. Just the usual bit of rusty residue in the header tank.

Thanks

Take off rad hoses and use Hosepipe. Run till clear, take out thermostat or the water wont get in.

Detergent of any kind may not be good for the cooling system or engine.

If rusty change the water/antifreeze more often.

I was told most detergent contains salt-however apparently shampoo is salt free and the preferred alternative for home made screen wash-maybe could use for flushing?

Thanks for the replies. Took your advise and stuck a hose in the rad/header tank/thermostat housing and flushed out all the crap.
