Going to flush the water system tomorrow. However, i put radweld in the coolant about 3 months ago (just under 3/4 bottle) as it had a tiny leak. My question is, would a flush product possibly open the leak back up.
I was thinking about taking the water hoses off one by one and giving a good scrub inside with a toothbrush. Any thoughts?...really cant be assed changing the raditor.
Thanks
