    Coolant Drain

    Guest-only advertisement. Register or Log In now!
    I've searched for a DIY on a coolant flush but no dice.

    I'm wondering if someone can point me in the direction of the drain plug, or hoses that I would need to remove to get the most coolant out of the system?

    Thanks in advance!

    There is a coolant drain plug on the the passenger bottom side of the radiator. When you're letting it drain take the lid off the reservoir it will flow better, and I'm not sure what hose you would remove I believe the plug is at the lowest point so you should be able to drain most of it.

    Then once you are going to bleed the system , the hose I used is behind the first firewall , they are the hoses for the heater core . And basically you pull the hose clamp off and pull the hose back enough so the little hole on the hose is exposed to the coolant but not all the way off. Then have someone rev the engine to about 2500rpm until you get a solid stream of coolant flowing . That's my experience with my coolant system. Hope it helps a bit.

    Use a "Vacuum Refill Tool" to refill you coolant without having to mess with the bleed port at the heater hose, and the 2 bleed ports at the back of the supercharger.
