Not that I remember?

is the passenger side exhaust manifold supposed to be split in 2 pieces in the center?

The OEM ones are two separated flanges.

It was time for a new pump setup, starting seeing contamination of the plugs, the level sender would become intermittent.

Guess after 25 years it did well.

Truck stranded me, sorta. The coolant connector at the heater core are plastic and one snapped off. Did a bypass, since I didn't have a way to directly connect them to the core.

Bought the Dorman metal connectors and 3d printed the disconnect tool.

Nice!

On my 99, I just removed those quick connects and plug in the hose directly on the alumimum tubing with hose clamps.

Been running like that since mine broke right after I bought it in like 2007 or so.

Couldn't get em off with the tools I had roadside, so did the bypass. The main body was still fixed onto the heater core.

I was tempted to direct connect, since these quick disconnects are purely for assembly line speed back when it was manufactured by teamsters. But I kinda like just replacing the plastic that degrades with metal.

I usually i just break them off in pieces with some pliers (they already leaked or snapped, so no sense in getting them out intact.)

They'll be so brittle that a few minutes with the pliers and you have them removed.

Unfortunately, on our SUVs there's no way to get those quick connects deleted because of the rear heater. I did upgrade one of the two SUVs to the Dorman metal upgrades. They are some tee quick disconnects.

Can't you just get straight connects and not run heat to the rear?

The ends were weak, obviously since they snapped off. The bodies were not, they were going to take the aluminum on the heater core with them hence the removal tool.

Yeah, but then my kids ridding in the back in the winter months would be freezing. :-(

I've been thinking about doing the Dorman ones in my Tahoe for the same reason. How'd you like them?
