What did you do to your NNBS GMT900 Tahoe/Yukon Today?

I have never had luck with that on modern, high pressure systems.
They always seemed to leak like crazy and you couldn't go but a few miles.

Unless you're putting significant load on the engine, you can leave the pressure cap loose or off and you'll have far less leakage. Yes, you obviously lose the advantage of pressurization, but so long as you have coolant (meaning not just water), you still have a margin before boil-over.

I've done this on a few vehicles, from an RV that developed in a tear in the upper radiator hose, to a BMW that had the upper radiator hose inlet break off the radiator (the hose couldn't hold onto the stub with pressurization, but held fine unpressurized).

@Scrappycrow Yes, these are the ones. Not any different as far as removal than the plastic ones.

NOOO, you just seal off the heater hose lines in case of emergency, just like folding a garden hose in half

I keep a nipple and spring clamps in the truck just for this situation it it arises.
