Removal of coolant in 3208 Cats

[Kevind767]

Trying to remove all of the old coolant from a pair of 3208T's in my B38 has always been a problem.

Any suggestions for removing all the old coolant, short of removing a freeze plug? (said tongue in cheek. I don't really plan on doing that)

Thanks

I put a vacum on the tank then pull a plug out on the lower front of the engine. Then put a niple on with shot shot of hose and then take vacum off and out comes the coolant in to buckets. I now use that line for a cabin heater so it has a valve on it to shut off in summer.
Good luck.

Thanks.
Will try that. Sounds like a nice and clean way to remove the coolant.
