So .... came out to truck this morning with about a quart of antifreeze on the ground.
This is the issue ....
Its leaking from the top ---- even through the bolt clamp looks good. Very small drip drip. Obviously the hose in natural alignment is not perfect as it pulls away. But thought it would be fine once clamped down. Its a loose fit with hose also.
Options ?
Was thinking one of
a) Weld a larger "lip" bead right behind
b) try and find a tighter hose
c) new thermostat housing
d) A bunch of gasket maker on the neck.
