    Coolant Bleeding

    Remove this ad
    Originally the vehicle was not heating up properly, so I thought maybe it had one of those garbage fail safe thermostats that got stuck in the open position. So, I replaced the thermostat today, only to find out that the old one was functioning properly when tested. Which leads me to believe the person who had it did not bleed it properly when replacing the coolant. It was a real bear getting the T-stat housing off and what not, but now its done and I'm ready to add coolant. I can see what looks like a bleeder screw on the top metal cooling pipe. It looks like it can be removed with a small ratchet. The issue I am having... I've broken two ratchets trying to get the thing off! I don't understand why it would take so much force to remove it, its just a bleeder valve, most cars just require a screw driver for removal with minimal force needed on a little plastic fitting. Is it common for this to happen? Just looking for advice and appreciate any input. Thanks!

    Vehicle is a 2004 Lincoln Aviator

    A pic would really help.

    I don't know bout the Aviators, but the Mark VIII's have a history of the cap on the coolant crossover tube seizing up. You cannot burp the coolant system properly without removing the cap. If the valve you speak of is indeed a bleeder valve for the coolant, likewise it will be nearly impossible to properly bleed air from the coolant system.

    I don't think I've ever heard of a bleeder valve on the coolant system. I thought that's what the radiator cap or coolant reservoir cap was for?

    I did get it off. Took a blow torch to it, came right off the 3rd try. Sorry for the confusion, its a bleed "cap" that sits on the top radiator hose. It seems to be getting to temp properly now, still a tad cool though...

    I've used a propane torch carefully on the side of the tube just below the lip of the plug with a large pair of channel locks on the top edge of the plug.

    In worse case, you can have a nut welded to the top go the plug and use a regular box wrench to remove the stubborn plug.

    There is a plug for sale on ebay.
