Re: Radiator puzzle
It's not that much of a big deal to remove your rad and refit the one on offer, so I'd be tempted by that offer, given the price. But it's a can of worms. You don't know what it's like inside. Here's a photo of the core I just removed from mine, after starting to have some overheating issues. I had previously tried flushing with detergent, as I knew I had greasy deposits in the system, but hadn't tried anything for the rust deposits. I was quite horrified when I saw the rust deposits on top of the tubes, with only a small number of tubes even open! That stuff was as hard as rock. I doubt whether a vinegar flush would have shifted it. In retrospect, I should have bit the bullet earlier, spent the $$ and got back to enjoyable motoring instead of stuffing around.
