Hey guys,

This is my first post and I figured I would start off by trying to help!!!

Title says it all, this videos shows how to flush and change the coolant in a Ford Ranger/Mazda B series truck!!!

 

nice job, few comments questions...

i dont think our systems are self bleeding? you didnt mention anything about that...
what about the water now trapped in the block & heater core that will be mixed with the 50/50 coolant?

I remember on my 5.0L there was a coolant drain on the block, im sure our engines have one as well (although im not familair with the 4.0 as i am the 5.0 that was in my old truck)
