Title: Draining hot water tank coolant hoses
Post by: kable on July 26, 2022, 04:55:48 PM
I am going to attempt to replace my hot water tank hoses.

I am going to follow Stu's method of draining the coolant by un-clamping the hose coming off the fresh water pump at the elbow joint and catching in a bucket.

But how do I drain the coolant in the hoses heading to the hot water tank?  They are fed by 3/8" hoses off the top of the fresh water pump and the thermostat and head down and connect to the long 5/8" hoses before heading under the floor pan.  So they are above the section being drained and I assume will be full.

How do I not make a mess? ;>)

I took them both off at the engine t-stat housing and then blew into one while the other was faced into a bucket. This got 99% of the water out of the circuit of the hoses. Once that was done I remove the hoses from the hot water tank and pulled them through that way. This gave me the minimal amount of spillage when replacing them.

Thanks
Not sure why I didn't think of that.

JFWIW,

EG antifreeze is toxic.
PG antifreeze is nontoxic.
