Cooling System wont drain

Postby txbiker » Sun Apr 07, 2019 4:52 pm

I am trying to get my 93 helix on the road for the first time since 2000. Changed the oil, trying to change the coolant but cant get it to drain. Made sure overflow bottle had fluid in it, applied wet dry vac exh to pressurize slightly but still not draining. Any suggestions. Radiator is full, overflow is 3/4 full, drain bolt out. WTF?

Maybe try disconnecting the hose at the water pump, catch the fluid to gauge how much rust and crud is in there.

Assuming the coolant system is crudded up. Is there something I can add to remove the crud in the cooling system?
Thanks

Not trying to be a smart-ass, but are you sure that you removed the correct bolt? And did you remove the radiator fill cap?

Your suggestions were the first thing I checked because I have been known to pull stunts like that so no problem with your questions.
