Plugged Up Heater Core

[vroom8]

is there any way to unplug a heater core, other than taking apart the engine?

Yes--the process is called reverse flushing, and I've done this on other cars...just not the LS:

Find the coolant lines that enter/exit the heater core...shop manual should be able to tell you which is which.

Then unplug both lines, and hook up water pressure (I've done it with garden hose with narrowed down brass hose attachment since I have good water pressure from the faucet) to the EXIT line.

You will see goop and crud come out of the INLET side (may want to attach the inlet side to another drain hose so the crud gets to the ground and not all over your engine compartment).

Reconnect both the inlet and outlet lines to their original respective connections and you're good to go.

*much easier than taking apart an engine* :P
