Shagtones,
I recently had the same situation with my LT4...dried rad. fluid on the inside of the hood and the belt had it on it as well. No leaks on to the floor but enough to leave marking on the hood.
In my quest to discover the best way to handle this, I learned there are a variety of economical ways to proceed, most of which included my ability to change the pump myself.
Lots of aftermaket pumps as well as GM / Delco pumps available ....anyhow, after careful discovery into the best way to handle the replacement I learned that if you take the car to a GM (Chevy) service facility and pay the extra $150 or so in labor to have it done there, you get a life time warranty on the pump and the labor.
Ok, thats all great but I was surprised to find out that this warranty also covers the 'Opti' spark module that is located directly below the pump. Providing yours checks out 'ok' at the time of inspection by the GM service tech doing the pump replacement, if the new GM installed pump ever leaks and causes any damage to the existing opti...it is also covered under the pump warranty as well....I spent the extra $150 to have mine done at the dealer!
96' Vette with warranty that 'IS' transferable!!! Go figure..........
My 2 cents worth!!
