    Default Blocked radiator drain

    Just went to flush the cooling system in the 205 and noticed that nothing wants to come out the drain apart from a small amount of brown muck... (I've got the expantion cap off)

    What is the best way to unblock this? Is there a trick?

    My GT was like this. We managed to unblock it with some flexible wire by poking back up the pipe. Also try taking the whole pipe off.

    Could it be that this blocked radiator be the cause of your blown head gasket!?! Shows you how important a good flowing radiator is. The original radiator in my Mi16 was the same...one inch of brown sludge at the bottom and 75% blocked. Luckily I replaced it before anything major happened.
    Good luck with car...sounds like a good project

    Make sure you take the radiator out and flush it really well in both directions. Maybe best to get it checked out by a radiator place just incase. Wouldn't want to cook another engine.

    If you are privaliged to play the trumpet, or its poor cousin, the trombone, you would be awear of the Trumpet snake.sounds like an English euphamism,but is what can best be described as a nylon brush on the end of a bicycle brake cable, which is flexable enough to get around the bends in a trumpet without too much trouble.They can be bought at most music shops for around $20, and are great for poking around water galleries and flexable hoses.If you do get one, make sure it looks like quality, as there are some shit ones on the market with just a piece of plastic hose,not the plastic coated steel cable, which will undoubtably snap off in the worst posible place.Shame to admit it,but mine lives in the garage now, not the trumpet case.

    It sounds like the whole system needs a good scour out.
    It is well worth having the tanks off the radiator and the core scrubbed or if $$$$ available, replaced.
    Sediment in the water jacket is a killer. A flexible small diameter high pressure hose and pump, shoved up all accessible channels of the block, check for calcification, blow dry.
    Watch out, some chemical cleaners you might use will turn alloy into cheese, (just not as tasty).

    Oily residue, needs detergent flush first.
    Then mechanical flushing of lumps/grit.
    Then chemical flush to remove stalactites/mites.
    Repeat mechanical flush.

    If you would not drink the water coming out of it, then it is not clean enough.
