Re: 94 Astro Heater Hose inline Vacuum?
So let me guess- you are commenting on your water shut off valve on the heater inlet hoses on top of HVAC module- that is vacuum actuated? so what is leaking? the vacuum or the coolant? if coolant- replace the water shut-off valve-- if vacuum - fix the vacuum hose-- some more detail may be needed to help you more......................
