    What's the part number for the block coolant drain cock assembly? I need to order a new one? [ I snipped these pictures from another thread - thanks to that OP]

    Is there a tundra online resource I can use to look up part numbers visually?

    Do you need both pieces or just the brass piece?

    Did it snap off during a coolant change? I’ve always feared that happening but have been lucky so far. I think the torque on the brass part is 9 ft/pds if I remember right.

    Yep, i'd be wary of touching the block drains. Just drain from the radiator and flush a few times, call it good. Gotta be quite a pain to replace a block drain if there is an issue.

    Been around the forums awhile and I've never seen anyone talk about breaking one, obviously it can happen though. I opened both of mine at 50,000 and had no issues,

    I wanted the part number for the drain cock assembly so that I could use it on my Supras. I did a coolant drain/flush on my Tundra and Supra, and while the Tundra flush was relatively spill free with a drain hose on the barb, the supra drain/flush was a mess with the coolant spilling all over my turbo's downpipe with exhaust wrapping . Would be great to change out the older style Supra's drain cock to the Tundra's newer version.

    Did you see my post with the part number? There's also another part number for other engines https://www.clublexus.com/forums/ls...41026-replacing-engine-block-drain-cocks.html

    Thanks Joe
    Looks like the "-09095 (from the club Lexus forum) will be the correct part number... it looks more like the desired 3/8BSPT size thread.

    I've attached a picture of what the Supra's drain cock looks like. You can envision what a splashy mess it'll create while draining.
