Thread: WTB S4 B4 Aluminum thermostat housing

  1. #1

    Default WTB S4 B4 Aluminum thermostat housing

    Looking for an aluminum thermostat housing to replace my plastic one on my S4 B5, part number for aluminum housing is 078121121J. Let me know what you've got ASAP as I'm in the process of doing the timing belt now and want to get the car back together quickly.

    I guess one from the states will take too long for you;

    The metal one you want is the same as any ABC 2.6 (C4,B4,100, B5). If you can't find one I have one for $50.

    If you don't need yours I'd be happy to take it off you hands for $50 + postage, saves having to get it from the US

    Good buy. Scarce as hens teeth, at least the genuine ones. Most places out of stock. I bought two in late '17 and they were probably US $150 each.

    I've seen them regularly sold for $50-$60 US on AZ but after postage you'd be looking at around $100 AU

    Here's some pics. This is 078121121F but will still fit provided you either remove a 10mm bolt from the cam cover backing plate or clearance the tstat housing.

    Seeing as US$60 is about AU$90, your shipping must be cheap. Most businesses are charging US$50 to ship to AUS. US shipping costs have at least doubled in the last 4-5 years. Sad days.
