radiator flushing

when i drained my coolant to do my fix, i had to open two drains, the main coolant drain as well as one smaller valve on the side of the engine block, as per the book.

do i need to do the same thing when flushing the engine every iteration?

also is just H20 good enough with Tacomas or should i go for an engine flush liquid?

finally, what is the radiator capacity in V6 4WD engine? the Haynes manual does not specify. should i dump the whole gallon, mixed with distilled H20 50/50?

thanks

 

Coolant flush steps
1. drain radiator
2. disconnect upper radiator hose
3. put garden hose into radiator fill
4. turn on water & start engine
5. run till water is clear then shut off water
6. when engine stops pumping water out hose shut off engine
7. reconnect radiator hose
8. add coolant till radiator is full
9. start engine & add coolant till it wont take any more
10. let engine get warm then let it cool off & check coolant level

 

This works for the premix stuff. Otherwise you'll have to mix it 50/50 with distilled water. ymmv

 

Total capacity of both block and radiator is just over 10 quarts.
