Seeing your floor has got me kind of wigged out for when I pull my interior apart. It's got a couple leaks I've been trying to address that have been going for a while.

That's a bummer about the carpet and floor, but that job looks 1000x easier than on the wife's Envoy.

That took me a bit north of an hour. Fvcking core was buried in that HVAC box on the floor. Had to recharge the goddamned AC when I was done!

Only a hour?!?!

Honest. The hardest part was getting the hoses off the heater core.

I putz’d around all day, but I had the original out in about 20 min. Even the dreaded screw at the firewall wasn’t too bad. Hell, I even put it back in.

Spent a few hours on the carpet. That thing is pooched.

The floor isn’t too bad. Looks like just surface crust. I’ll spend a few hours this week with a scraper and wire cup, then give it a coat or two of POR15.

That blows. Seems like they build the damn cars around those things.

According to the service manual, that’s how these trucks are supposed to be done too. Happy to report they are full of ****.

I’m trying to decide whether or not to put the heater bypass valve on at this point.


Anyone out there have any feelings one way or the other about the plastic valves reliability on the coolant system? Is the return on the air conditioning worth it?

Not scientifically speaking, I feel like it helps a little. Not as much as having a proper functioning recirc. door, but a little. If you do keep it, just replace it now. $20 worth of insurance. It really needs some kind of heat shield to keep from getting fried by the exhaust manifold.

So I grabbed the solenoid from the junkyard, and attempted to get the valve too, but it crumbled in my hands. I guess I’ll just add it at this point, and keep an eye on it. That one in the junkyard lasted 20yrs, so if I get even half that, I guess that’s fine.

What are your plans for wiring up the solenoid? It originally ties into the temp control knob on the HVAC controls. When you turn it past the detent on cold it activates that solenoid.
