System Coolant Flush

[Eazyy]

Hey guys pretty general question regarding my rb20 gtst. So I've just done my Welsh plugs as they rusted out due to my radiator being old and rusty, also doing a manual conversion and putting a new radiator in with new hoses etc. Whilst I was doing my Welsh plugs I noticed a shit tonne of rust inside the galley if you will. I'm wondering when I get everything back on if it would be wise to do a radiator flush with flushing products or would it be too risky to unsettle everything inside? Just want the radiator system to be as clean as possible after the new radiator is in. Cheers.

Usually I would recommend to just run the hose through the block, probably best done with the thermostat out.

I have always wondered if there was a flushing product around to remove the rust and convert it, similar to body rust converter, but I have yet to find one on the market. You wouldn't want that rusty crap blocking your new radiator anyway.

Yeah you're right defintetly don't want that shit in my new radiator. When I say rust in the galley I meant like chunks of it I could spoon out with my finger hahah

50/50 white vinegar and water would make short work of the rust deposits. I have no idea how long it would take though.

You are unlikely to get it all out
