Totally agree about the right tool. But not sure if I'll be able to swing getting an impact wrench at this time..may look at renting an electric one, if thats possible, since I dont have a compressor.
I read the Gates kit water pump has a plastic impeller so Im wondering if it's a good idea. But I'll keep it in mind as I research other ones (such as CRP, Goodyear..)
Thanks again for your input.
