Wanting to flush my anti freeze.

[Ruger]

My oil and tranny fluid are extremely clean.
I did see the drain valve is in a very tight spot on the radiator..."WOW"
But my anti freeze is dirty as hell!
I wanted to put a flush kit on the heater hose, to be able to flush it out.
"No chemicals", just flush.
I don't know which heater hose to put it on?

When I want to flush my coolant system.
I take the lower rad. hose off and let it drain.

Then I stick a garden hose in the top (cap) and flush

I take both heater hose off and stick a hose in one till clear water comes out the other one. then I revesre and flush clean water into the other hose till clean water comes out the other one.

Then i flush water in the upper rad hose till clean water comes out the lower.

Not sure if this is the best way, but it's the way I always done it.

Its the smaller hose coming off the thermostat housing.

Removing the thermostat and disconnecting both radiator hoses at the radiator works well. Shove the hose in the top hose and let her rip till it is clean. Do the same for the radiator

[Ruger]

Thats a good idea. That way I can put a new thermostat in at the same time.
I will do it that way. I will pull the heater hoses and blow water through that too.

Got her flushed out and clean. I even flushed the heater core seperately.
I broke that damn heater valve thing where all the heater hoses go to.
Local parts store had it on hand. I was shocked!
Wow, nice and clean, and blows strong heat.
I did put the "better" thermostat in it.
My tranny fluid is so clean, you can almost see through it. I don't know whether to change the fluid and filter or not at 123k I probably should.
Someone must have done it along the way since it is so clean.

Factory service manual calls for servicing every 30k miles, 12k for harder use. If its been a while, go for it. Its great it still looks good, change it and keep it that way.
