Coolant reservoir

[Jv50347]

1996 Chevrolet K2500 5.7 replaced thermostat because the heat was a little cooler than normal and noticed it was pushing fluid into the reservoir but not pulling it back out. Runs great with no overheating or leaking. Removed the hose hose from radiator to the tank a blew into it and had some resistance before the fluid bubbled. Any advice would be appreciated.

Replace it with a new hose?

Mine was clogged with rust crumbs. I couldn’t find a suitable replacement hose at my LAPS so I removed it and wallered it out with a coat hanger. I also ran some Evaporust Coolant System Cleaner through the system (per instructions). Good stuff - gets the rust out, but plan on doing lots of flushes. Coolant runs nice and green now. (1995 Tahoe)
