Where's the engine block drain plug on an F6A engine?

[soldave]

As the thread title really. Where's the engine block drain plug on an F6A engine? Gonna be replacing some old coolant hosing in the next few days and want to do a good flush of the cooling system. Would like to open up the engine block drain plug(s) to make sure all the rubbish comes out with the coolant rather than settling on the bottom.

Cheers for any pointers you can give me

I havn't looked closely at a f6a but I would assume they would have welch plugs like many other engines....replacing those for a coolant change is a bit of overkill!!!! older style cars had a drain screw/bolt just below the water pump...

I would just do a normal coolant flush and then refill it with good coolant...

I doubt you'll find a drain plug on the block. Radiator drain plug is the lowest point in the system anyway.

Thanks for the reply. Probably very true too

Food for thought, take your thermostat out, put housing back on, disconnect top radiator hose from radiator, disconnect bottom hose from radiator, put as much water thru the block going from top hose so it all comes out the bottom hose (obviously), once it seems to run clear, try pushing water up the opposite way from bottom hose to push water out of the top hose.
By doing this you flow water in the normal direction, then by reversing the water flow you remove scale and build up that has clung on with the normal dircection of flow.
repeat process for the radiator also, dont forget to put your thermostat back in either
There is a tool that you connect the water hose to and also an air line to force the water thru in both directions, not sure of the tools exact name but it "power flushes" the system.
Hope that has helped.

blueprintute that is exactly what I do for a flush of the system (good old garden hose), then I run a cleaning product through the system, flush again and drain (using compressed air in the top and bottom hoses) then fill up with good coolant.

dave if your taking your timing cover off, and having heat & oil probs.remove water pump and check it,plus flush out rust straight thru out thermo housing.plus check oil filter water cooler might be leaking oil between filter & block.cheers.
