    I just used a piece of pipe from another place on the car since I had spare. Ridge or not, itís holding just fine for many years now.

    I have a pipe bead roller - a luxury that's useful for those few times you need it.

    If you send me a pipe and return shipping I'll bead yer pipe. If ya know what I mean.

    Thanks guys -- my friend already has my pipe and is going to weld the otterstat port closed, so I should be good to go there.

    Normally Iíd say to pick up some cheapo 1.25Ē aluminum tube and sell the otterstat piece, but if itís leaking then no sense in saving it.

    whenever making coolant pipes make sure there is a bead on each end.
    Luke does it the proper way with a bead roller, you can also improvise and weld a thin bead around the circumference of the pipe. Anything to stop the clamp from slipping.

    You dont want that pipe coming off, especially if you are near it. I know some guys say it is fine, but it simply is not. I have seen hoses pop off due to lack of a bead - it is a mess. Even more so if you are near it.

    My friend wasnít able to get the coolant pipe welded, but his friend had a perfect length pipe and the tool needed to make the bead, so now I have a brand new straight pipe that fits exactly as it should. I drove back to my dadís on Sunday, and then back home in the DMC with zero problems over the 2.5 hour trip.

    Thanks again everyone!

    Itís a temperature switch mounted on the bottom of a coolant pipe on the driverís side of the engine bay. It turns on the cooling fans when the coolant gets hot enough. Itís also prone to leaking or falling out and dumping all your coolant on the ground. Honestly, Iím surprised it took this long for mine to fail. People turn the pipe over to reduce the chance of that. With an EFI conversion, you can use the coolant temp sensor and the ECU to control the fans instead. You could probably rig up something like that without EFI, too, if you know some electronics and can build a circuit to read the sensor.

    I have no idea why itís called an otterstat. http://store.delorean.com/p-6348-coo...otterstat.aspx
