    z06 water pump

    My searches show some folks have been able to put in a z06 pump which runs about 100 to 150 cheaper. Some posts suggest it has different specs but still fits and some suggest that some modifications are required. Does anyone have a current answer or direct experience? If so will my install require further clearance such as full radiator removal?

    Thanks!

    So, thermostat or no? Ive read people nonchalantly referencing 160s but they also reference a required pcm update. Ive been furloughed and had hours cut due tobthe "ACA" so the non necessary costs will be avoided.

    Re: z06 water pump

    The zo6 pump will stick out very close to the stock radiator, but it will fit. If you run it, you will not be able to upgrade to the thicker alradco or Ron Davis radiator. If you're not planning on it, it's not a big deal. It may make it trickier to slide your rad out when you want to work on te front of the engine though.

    ----------

    Oh and you can replace the tstat without a tune. Te tune will just optimize it. It can be done later. IMHO, a 160 stat is too low for an uncammed car in a cold climate. You won't be able to heat the cabin in winter. If cammed or charged, however, your engine will be running hotter, so you will def need it.

    When I was uncammed I went from a 160 to a 180 for a happy medium. Lingenfelter sells a 180.

    Thanks for the reply! I just replaced the stock radiator about 1000 miles ago and the car is stock other than tires and busbings etc. No plans for fi or cams and im in Indiana so cold weather is alraedy rearing its head. Ill proceed with the z06 pump!

    the previous owner of my car had an ls1 water pump installed... and recently when my friends water pump in his v went out.. we got the ls1 pump as it was in stock and the V pump was 100$+ and not in stock.. same deal, close to the rad but he was able to slip radiator in and out later without much issue.

    I ultimately got a Thompson CTS-V LS6 pump with a lifetime warranty from NAPA for $199. 180 degree thermostat was $13.25. I paid $242.xx after tax for both of those and coolant. I'll have installed them by the end of the weekend!
