Coolant flushing problem

[Mike94ranger]

94 ranger 2.3 when I attempt to drain coolant using radiator plug only get what is in radiator. How do I drain entire system?

Jack up the rear end...

Look for a drain plug in the block. Some engines have them and some don't. I don't know if yours has one or not. Otherwise, you are looking at maybe trying to disconnect a hose up higher like a heater hose and the lower radiator hose.

Take off both heater hoses at the firewall, lets air flow in as engine drains<<< just this should let coolant drain from the "petcock" in lower rad

Remove rad cap, lets air flow in as rad drains

Remove lower radiator hose at radiator end and all coolant will drain out, well as much as possible<<faster draining but messy

Leave heater hoses off when refilling, when water/coolant starts to flow out of the hoses all the air is gone, put them back on

You should Reverse Heater hoses at the firewall every year or so, it keeps the heater core cleaner so it lasts longer, thats for ANY vehicle
