I’ve got one leaking as I type this.. 275k and I’ve chased coolant leaks and replaced 3 different hoses now in the last year. I’ve done two by the throttle body, the thermostat bypass (short one.. PITA), now a Tee hose leaking.I don't think I've seen nor heard of a failed T-hose yet.... has anybody?
Gonna bite the bullet and do the whole tee assembly even though the dealer did tees about two years ago. I might just go ahead and do the oil cooler hose too, now, for some piece of mind
