Thanks Gentleman, the truck and house build just got put on hold, I had a heart attach last night and things will need to sit for a while. If I cannot get this one clean without making it leak I will order another one.
Sorry to hear bout heart attack.
Here is my take....on 1 truck I purchased about 130k miles on it...ungodly amount of hours though...logging service truck....
Coolant was a nice rich n thick nestle quick chocolatey brown goo....
Flushed with prestone rad flush...more brown goo...flushed with tap water....more brown goo...flushed several times ti came clean...removing block plugs.
Added distilled water n coolant....finally
Water pump began to leak....lost coolant
Replace pump....flushed with plain water...ran few days like that check system...top up w good fresh coolant and diztilled water.....week later rad leaks...bad...need get hkme so dump water in...another 4 gallons coolant $$$$ gone.
Replace rad....and thermostat...and hoses..all hoses....run water....no leaks...week no leaks 2 weeks no leaks...add coolant n distilled water...drive for months....excellent...
Get up go to fuel...engine blows da #÷€$ up...4 more gallons of $$$ down the drain....engine blowing was nothing to do with coolant system but you get point.
Flush at yer own risk. In case ya lost track that was a total of 16 galloms of coola t a d 16 gallons of distilled water $$$$ gone...plus time.
Ye be warned....
Now get well and heal ...get life on track......then get in there flush and replace rad and prepare for a water pump possibly...budget it...a thermostat and hoses are good when rad swap.
