    Default 2004 Beetle coolant sensor location

    I am going to replace the coolant temperature sensor in a 2004 VW Beetle with a 2.0L, 4 Cylinder engine. Would anyone by chance know where the sensor is located? Some places state it is very hard to replace (labor), but with the limited information online, it does not seem to be a hard task. Any help would be greatly appreciated.

    Good/cheap source for a lot of "Where/how/when" auto stuff is the Autozone site; probably AdvanceAuto site; Napa; etc.
    Not saying it's the best place to buy parts but they all have decent enough on-line repair manuals, etc.

    Not sure exactly where it is but you can seen the wire loom with the spark plug wires in it in the lower left, upper right looks like the intake pipe, lower right seems to be an upper radiator hose.

    Thank you very much! The engine should be cooler now, time to get greasy or anti-freezey!

    What issues are you having where you want to replace that ?
    Curious as they have some other common issues.
    I found out after some research as after selling my Tacoma on Super Bowl Sunday, the used car dealer I asked to open, the best car they had on the lot was our new 01 Bug with a 2.0.
    They have a plastic impeller water pump on these, on my 01, anyway.
    Also, there is a clunky looking plastic adapter that leaks and has a bunch of hoses and usually a sensor in it, that needs replaced as well.
    Too, you should use VW's special fluid, which has specific properties, and I believe, distilled water to mix @ 50/50 with it. If it's an 04, I would also just change out all hoses as a good preventative as well. If not now, then soon or next year.

    Good luck.

    The VW Beetle is plagued with issues. I had a system scan on the car due to the engine light coming on, as well as the airbag light. The coolant system came up on the codes and there were several possibilities. The problem could be low coolant level, bad water pump or the coolant sensor. The first two were obvious and easy to detect.

    It took but 5 minutes in total to replace the coolant sensor. The mechanic's around here thought I did not know anything about auto repair and all lied to me. Stating that it is very difficult to replace the coolant sensor and labor would run several hours. What a joke. The Beetle is now back to normal and apparently the airbag sensor is a company recalled issue.
