Drain Plug (Radiator Flush DIY X5 2003 4.4i)

[chubyball]

Anyone knows where I can find the coolant drain plug on the engine? Is it locate on the back of the engine next to manifold area and near the passenger side? I am planning to flush my old coolant out and replace with new one.

Thanks for any inputs,

you have a 3.0 right? its right between the headers...

I got 4.4i, what do you mean by headers? on the side front engine, back or top side?

[hayaku]

it should be on the right side of the engine under the headers (exhaust pipes)

search this forum for thermostat or waterpump instructions. i posted pics from the TIS for these procedures and it includes how to drain coolant from the block...
