Hi all,
I have a curious problem with a couple of radiator hoses on the custom radiator on my 1UZ.
As you can see in the first pic, a short length of swollen hose that was leaking out of both ends - was fine one day, leaking the next. The hose clamps appear to have slipped a tooth - maybe I've over tightened them (about a year ago though) - see second pic - the leak was definitely out of the inside of the hose and not between the layers of rubber.
I've only been driving around town lately and it's quite a few months since I've done a 100km+ trip.
The ambient temperature has been pretty cold (for here anyway) with a -2 deg C outside the other night - the ute is always in the garage though.
Am I being paranoid, thinking that possibly I've got a blown head gasket and the system is over pressurising? the overflow bottle fills slightly (as always) when hot, but has never (to my knowledge) overflowed. Is my radiator cap too higher relief pressure? (I'm using a 21-25 pound cap and have been for over a year)
Now the strange part, I fixed the two hose clamps and section of hose, and the next day (today) I find that another hose on the outlet of the radiator is leaking.... damn it.... so maybe I'm not paranoid, or maybe my radiator cap relief has decided to jam closed (looks ok).... I don't know
Cheers in advance for your help team,
Muzz
