I have a 96 Bronco 5.8L. I am replacing my thermostat and decided to replace the coolant at the same time as I do not know the last time the previous owner did so. My service manual states:

"To drain the radiator, open the radiator draincock located at the bottom of the radiator and remove the radiator cap or supply tank cap. The cylinder block of the V-8 engine is drained by removing the drain plugs located on both sides of the cylinder block (6010). The six-cylinder engines have one drain plug located at the right rear of the cylinder block. "

There is no diagram that shows me where the cylinder block drain plugs are. Could someone please give me a description of where this plugs are? Thanks!

i never seen any block drains from the factory. if you pull the lower raditor hose it should remove most of the water from the block. you might want to replace both hoses and heater hoses at this time anyway. ..mike

i think they are talking about freeze plugs but there is no reason to do that, like colin said pull the lower radiator hose and let it flow. also pull your heater hoses and drain them as well

Instead of pulling the lower hose its easier to just open the radiators cock...

Thanks for the advice. I will remove the hoses and see if I get any more coolant to drain. Thanks!

I did pull the lower hoses and plenty of fluid ran out. When filling it back up I ended up using the Haynes manual recommened amount of fluid so I guess that was all of it. Thanks for the help

all you have to do is turn the little valve at the bottom, all the fluid poors out, close the valve, fill it back up 50/50 mix, and be done.

that way, no hoses to put back on

come on, tell me u knew about this :toothless

I pull the lower rad hose let it drain and with the garden hose on high I blow it through the fill cap and FLUSH the system ! (same with the heater core).
So much crap came out !!

Well sounds like the job is done, but there are plugs (with hex heads in them) that you can use to drain the block the rest of the way. If you want I can find them and post a pic, my engine is on a stand, and there should be some coolant left in there, it hasnt been rolled over yet.!

I have those on mine as well.

The plugs are on the bottom of the block, just above the oil pan rail. You may have to remove the starter to access the one on the passenger side.

However, I warn you not to bather with them. I can almost guarantee you will need a torch and some penetrant just to get them to break loose.

another idea is to install one of the prestone flush kits. basically comes with a t fitting that splices into a heater line with an adapter to hook up a garden hose. Then you remove the radiator cap, start the truck, and crank on the water. does a great job flushing out all the junk and only costs like $10 IIRC.

DAMN! I feel stupid. I've had that in a few vehicles and never realized what they were for. That's good to know.
