Coolant overflow/reservoir tank question

[liquify33]

Take a look around the heater control valve. That plastic may have a pinhole. Wrap some TP around it, if it gets wet it shows. Also check at Heater hose QD at intake manifold.

The line was clogged. I have/had a lower intake manifold leak and didn’t realize coolant was disappearing because the line was clogged. I needed heat recently for the defrost and just got cold air.

Did some digging, unclogged the line and then blew the snot out of the intake gasket driving it like a rental. In process of repairing and overhauling now.

If you only have a minor leak/weep the Delco Cooling system seal tabs do work some. If it's pissing out then it won't.

Oh no it sounded like a light rain when I parked!
