Need new waterpump. Should I replace opti?
The topic says it, my waterpump is leaking and the mechanic recommended replacing the cap and rotor on the opti. My question to you all is this: should I replace the entire opti-spark unit, or just the cap and rotor. The car is approaching 120k miles and I've had it since 108k and this is the first major work that I will have done. I just replaced the plugs and wires and will be installing a 160* thermo as soon as the waterpump is replaced. Is there anything else I should get done?
Also, which waterpump should I get, a stock or aftermarket one, I know there are several aftermarket ones available, but are they worth it? If I go with stock, are all LT1 water-pumps the same, i.e. F-body, caprice/impala, corvette?
Thanks.

You mentioned you have had your car for approx 20k miles.......do you have any idea if this is the original opti? I would strongly recommend replacing the opti NOW!!!!!!!!!!! Save yourself a future headache........I speak from experience!! :eek:

since you are not sure of the age of the opti, and going to be replacing water pump anyway..... I would replace the entire unit.......... :flag

Hi Josh, You being a student, your cash situation must be limited. If you plan on keeping the Vette for a long time, I'd go with the electric coolant pump (Meziere HD), replace the entire opti (maybe with a Dyna-spark), and reprogram your ECM to lower the temps the fans come on. If it is just to get you backon the road and the mechanic is doing the work, at a minimum, replace the opti (cap and all) and replace the water pump with an AC Delco OEM new pump. :thumbs: :chevy

A 95 has the newer opti. It's also the less expensive opti. A cap and rotor will only save ~$50 over the whole unit. I'd get a new opti from Chris May at Superior Chevy. https://www.superchevyperformance.com/

Now you're cooking. Oh, just a side bar, my son had a poster hanging in his dorm at college; a 5 car garage with Vettes, and other fine cars, attached to a beautiful house with babes walking around and the caption was, "Motivation for a higher education" Stick with it. :thumbs:
