Cold weather finally made it this far south. I noticed the Ranger's heat was very lacking. I checked and changed the vacuum lines to the canister in the fender and to the heater hose shut off valve.
Then I checked the blend door actuator and all was well with it. So I ran the truck and got it warmed up and the hose coming from the heater core was cold while the one going to it was hot.

Using this method:

I got this out out of the core into a 5 gallon bucket:


I swapped the heads on my truck last year, and this is what must have been knocked loose along with the normal accumulation to finally cause it plug up almost solid.

I used the Prestone radiator flush kit. Worked awesome. Mine was full of rust and sludge. I may have had the coolant ford put in in 95 in it when I bought my truck 😂🤣😂
