Plugged ram heater core

[GTyankee]

I have not traced the 2 heater hoses for the full length.

Yesterday, i was using YouTube to see how those hoses are routed.

One video showed a 3 way valve, that is located under the air filter box.
The guy making the video, disconnected the huge air hose that is connected between the Air Filter Box and the Throttle Body.
Then he unscrewed a clamp & lifted up the whole Air Filter Housing.
With that out of the way, he talked about the 3 way valve that was hidden under it.

He used 3 water hose clamping pliers on the 3 hoses

Then he said that he was only checking out that valve & i got bored & shut the video off, mostly because the video had terrible lighting

Good move! Quick, easy heater core fix. I've had the same thing happen on a vehicle I owned. There could be bits of gasket material ground up to bits, ...and did someone ever add hard water to the cooling system ...say, to re-fill after a coolant flush? Best to only use purified/distilled, or pre-mixed coolant ..but you probably know that.

Either way, now the heater works ..just in time for upcoming winter.

Yup!

what's everyone doing regarding the water in the core post flush? do you just leave it and let it mix with the coolant post flush? or is there some way of getting it out? i'm probably going to be doing this via the garden hose method here in the near future.

also... for those doing this with a garden hose setup - are you just collecting the antifreeze in a bucket and once you get just water (and gunk?) running it onto the ground/drain? or are you collecting ALL of the water you're using to flush?

what are you doing with the liquid you DO collect (not sure what i would do with it as pretty sure local auto store wouldn't take it like they do oil)?

(no judgement from me btw regardless of what you do... just looking for info here is all)

I just left it in... it's such a minimal amount that once I added my coolant back to it there were no issues.

I do collect the antifreeze in a bucket. Once it's straight water I let it drain onto the ground. I don't know about where you live, but in Alabama antifreeze isn't considered hazmat and it can go in the regular trash as long as it's in a container. I do believe some places will take it though.
