I think I opened a box of worms when I popped the hood on my Safari this week.

One more issue I just found was that the top and bottom radiator hose is suckin in on themselves once the engine cools and I have to remove the radiator cap and they expand back to their right size, I got a new cap in the hope the seal was forked but it's still doing it, the hose looks new and properly fitted, is it just a weak hose or is something sinister lurking, I cant see any leaks as of yet as its night but the water level has stayed the same. Any ideas.
again huge thanks
