coolant in cab - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I think I know the answer to this, but want to see if it could be anything else before I replace it. I have a pretty substantial amount of coolant coming the cab under the glove box. Is there any thing else it could be besides the heater core? I have an ac truck and don't really want to replace it if I don't have to. Thanks.

Heater core no doubt. Jim

Slight chance of a loose heater hose connection. Pretty sure the connections are under the hood but *maybe* the coolant could follow the nipple to the core, then drip inside the cab. But a bad heater core is by far a stronger possibility.

Yup, I'd guess heater core pooped out. Fun, fun, fun.

BTW--Because getting the box off is such a pain and if your heater doesn't
blow HOT, do take the time to make sure the flap in there shuts tight when closed.

The best part is that I just replaced the inner fender and had it out. I always seem to get to take things off multiple times. Super awesome.
