it's been fine for almost four years, then one day a hose popped off behind the firewall. I just put it down to a clip working loose. then a few months later the rad started leaking, swapped that and all was good for a couple of months and then a hose popped off next to the filler cap, which I thought was odd. popped it back on nice and tight and then a while went by until last week, when it started popping the hose off that goes into the thermostat housing. that one has come off four times now. haven't checked compression, have no idea how to check leak down? but I do almost have one coilover on lol
