Siezed Engine Drain Plugs - Alt Method to Drain Coolant

Post by 36 Tri »

Hi,
Can't get the drain plugs out of the manifolds nor engine to flush the coolant antifreeze. Can I just hand pump out most from the cap (snake down small tube), then remove tubes from thermostat and pump out from those locations?
Most is better than none?
Thanks... John

careful I had some stuck ones in Chryslers and some twisted off and had to used chisel to get the leaves out. I bought a set o 8 point sockets to use on square plugs and use 1/2 extension to turn internal plugs. Lot o extra work but got them out. Replaced with brass ones.
