    Thanks Wiz... I'll see how things pan out. Think it's about time you retired and took over the NSW Zed300 Permanent Tech Garage...
    I know, I know, it's my old soapbox theme, but still think it could work....

    Hey Mike, I got the week off work so I might be able to lend a hand, but I can't say that I'm entirely sure what to do, though I've got the general idea.. >_>

    Thanks for the offer, 'Sky', but I'm afraid it might be the blind leading the blind :):)
    Some of the guys (thanks fellas!) did a full plenum pull on an earlier engine and, I'm afraid I just had to stand back and watch their expertise!

    Haha I just took a quick look in my engine bay, and located the driver side turbo coolant hoses. Think you would need to remove the accordian hose and work your way through there (hope you don't have fat hands). Can't do it from the top due to the brake MC blocking it.

    And after owning the zed for a year plus I just realised my EGR was missing, and it has the blanking plates. Most probably deleted by the previous previous owner, though under plenum water hoses by-pass was not done. So you are partially right about the blind leading the blind :p

    Hey VS....

    I beg to differ. That is, as long as the rest of the cooling system is in good working order.

    I have had several instances over 35 years of driving all different kinds of cars where I have had a thermostat go bad, without the ability to secure a new one, or fix it right away, and pulled the old one as a temporary way to be able to drive the car. I had to do this once on an old pontiac grand prix I had in the dead of winter, and I had to put cardboard over the radiator to get enough heat to make the heater work.

    Taking the thermostat out makes it so that the water pump is constantly moving water through the motor/radiator/cooling system. This never gives the coolant enough time inside the block for the motor to reach full, or normal operating temperature. Thats why I said that it will effect fuel mileage because the CTS is reading a "cold" motor and trying to compensate by adding fuel and making the mixture more rich.

    The reason any motor has a thermostat is so that it can reach, and run within the range considered normal operating temperature. If it was as you say, there would be no thermostat in any motor of any car.
