x2 on that - the original coolant sludge in the lower parts of radiator can be thick as a wet sponge, some water will pass but not much. Add the stopz leakz, and that sponge becomes more like a brick. Flush may not get rid of it. Be sure to check radiator when truck warmed up. Feel fins top to bottom. If big temperature difference, bottom would be colder bacuse no circulation. Summer is comming and you will need a 100% radiator.

Haha, if you recommend it I will add it to the list. How long will it take me to pull out the radiator?
I just got the crankshaft pulley off, had to make a tool

Since it is a D2 flush is about all you can do, most shops charge enough to rod out a plastic tank radiator that you could buy a new one. You can flush in the truck, it just has to go somewhere. SWMBO will not tolerate a large puddle of gunk antifreeze on her side of the garage.
Fun fact - usually the spouse that parks on the left side of garage sleeps on left side of bed.

So, leave in and flush?
or
remove and flush?
What would be best?
Spike555, I had already unhooked battery and electrical due to Head Gasket work, I guess next time.
Here is my setup -

Very best is remove rad and take to indy shop for hot flush. At home, leave in truck. Material inside is not loose granular stuff. It is a sludge (Dexcool mud) and scale (calcium stuck to sides of tubes). Reverse flush always works best. Garden hose and a couple of rags around it to seal up and flow thru bottom and out top. If engine is not running you can't circulate chemicals, so garden hose is about it. Once everything back together flush whole system with a few jugs of distilled water. Take it from a country bumpkin, well water has no place in a radiator except as emergency. Too much calcium to boil out.
D2 radiators have very delicate plastic nipples that will break if you sneeze on them. Slice old hose off with razor, put new hose on with a little soapy water lubricant.
