A heads-up if you have a 2.8 or a 3.1 or 3.4 transplant in your Fiero. Should you need to replace the water pump and it doesn't come with the water pump gasket, you may be in trouble. Even the timing gear cover sets don't come with the water pump gasket.
I have been contemplating addressing the coolant leak coming from the area of my water pump. It's a new pump, so it isn't the bearing/bushing. Only has about 20 miles on it.
In my search to find a gasket, I found that neither O'Reilly, AutoZone, Advance, nor Rock Auto has the gasket. They either list it as Not Available, or Notify Me When Available. I finally found it at NAPA but it isn't in stock at any of the North Georgia stores. They must order it from the Nashville warehouse. You might want to order one and keep it in stock. Cheap insurance for $3.49 plus tax. Some stores will add a shipping charge that will be more than the gasket, but it's still worth having something that may soon be unavailable.
