    Mkiv is the same way Wilson. The Tstat is on the passenger side of the block, towards the oil pan in an oddly configured housing lol

    If I'm not mistaken they switched to an internal water pump and if that's the case replace the TB. I'd switch to the newer purple G12 as well... Stuff is AMAZING.

    Im gonna tell him to get the ecs ultimate timing belt package, includes timing belt, accesory belt, water pump with metal impellar, thermostat, and orings

    That's the stuff. I found a local place that sells the same stuff for about 4$ cheaper so I use that instead but it's still great. Plus I love that it's purple lol

    I have yet to change my TB on the new motor. But the guy before me had already done it (this I know because he was a VW tech). It's about a 15 min ordeal on the 3, just really simple.

    Thanks for the help guys, this is exactly how I found it. I didnt use it for the thermostat though, cuz he had a book. I am gonna use it for the coolant pump, timing belt job Im helping him/doing for him. I can always count on you two for previous gen stuff.

    And ya the coolant pump is internal for whichever one of you two said that. Seems like a pretty long but pretty easy deal. Im guessing its gonna take me 6 hours. Any bets?

    Ya that would be great if I did it in 5 hours or less. I have also just realized i am gonna need the stretch bolts(motor mount) as they call them. I wonder if dealer or auto parts joint would happen ot have them on hand? Gonna have to call them

    What a friggin disaster the timing belt job was... A bolt was stripped on the vibration dampener, one of the allen heads. spent 2.5 hours drilling, grinding. Extractor broke inside the head, and had to grind the whole head flat to get it out. After that, we were putting the new timing belt on all marked and everything. I was holding the crank section in place on the bottom and he was doing the top cam area. He then says, crap man I think it moved. He suspected the cam gear moved. So, I said I hope not cuz I cant find TDC. Put everything back ttogether and it runs like ****. It has to be atleast a tooth off. smoke pouring out the exhaust. Lmao Minus the grinding of that bolt it took about 5 hours, but car does not run right.

    Just fyi the coolant pump impeller was not even on the pump anymore. completely broke off the shaft. I picked all the pieces out.

    wow that sucks man

    you need to get the timing marks back to line up

    start with the crank then cam and redo the belt

    you can make sure removing the #1 spark plug and making sure the piston is on top

    i bet u put everything back together, right?

    should of checked b4 putting it together if it runs ok.

    i always do so. just to make sure. the engine can run with out coolant for a a minute or two

    All the gears have marks on them for TDC. The cam gear is pretty tough. My personal favorite is to mark all three gears with nail polish and mark the old belt before removal. Then mark the new belt and count teeth between marks to ensure proper line up...

    There's a plug on the transmission housing that's sole purpose is to show when the motor is at TDC, so just line that up and line up the cam gear

    Ya we did the mark n match way but he moved the cam gear before belt was on, so its ***ked. The diy I used showed only one mark on the cam gear to line up, but his had 2 marks

    Ok UPDATE:
    Kid brought the car to a vw tech (his gf's dad) and here is what he said.
    He said we did a great job and the timing belt and coolant pump was a success. The car now has a blown head gasket. So, he can fix that cuz I did the other job for free and I dont wanna do a head gasket Fo FRee.
