Coolant Hose Change

[bill1013]

Aloha Y’all,

Does anyone know how to get the remaining cooling hose part off at the firewall? Appreciate any help or suggestions before I screw it up further. Mahalo for your assistance concerning this matter. Aloha!

P.S. Any idea the cost?

you probably already got them off. but there's basically 2 ways. some just cut them off to save the hassle since they are being replaced anyways. Just don't damage the aluminium pipe inside.

if you can push the fitting back, reach back and squeeze the tabs at the red arrow, it is supposed to release the tabs at the green arrow and pull off

easier said then done sometimes.

i think its like 14-15bux off amazon. one of those stupid tools you dont think you need. but fight with the hose end for an hour or break the end off your heater core and then try telling me its not worth it

That part that broke is part of the hose and not the tee itself. You will need that new piece plus the 2 tees.
