optispark question
I just purchased my first corvette, 1993 in decent condition. The first thing I noticed was the car was running hot and the coolant looked like rusty water. I decided to flush the system and replace the thermostat. Needless to say I ruined my optispark from what I've been learning. So now I'm going to replace it along with the water pump as everyone recommends. My question is, how do I keep this thing from getting wet again? Just opening the air bleed on my thermostat housing could leak down on it! What about water puddles on rainy days?? It seems like a poor design if it's that sensitive. Is there anything I can do to protect the new one ?
Thanks!

Pack rags under the bleeders before you open them. Some folks have added a drain hose to the weep hole under their water pumps, to try to keep leaking coolant from getting onto the Opti. I've never heard of an Opti getting drenched by driving on rainy days.
Consider an aftermarket Opti that is actively vented, as opposed to the passively-vented OEM unit, as a replacement.

Drainage - disconnect the lower radiator hose from the engine block first. That will drain both the radiator and a portion of the lower block. Once drained - loosen (but do not remove) the waterpump bolts then tap the housing loose. - allowing a small trickle.
The Delco pump I received already came with thermostat and waterneck already installed.
Not sure what comes with reman/aftermarket tho.
Opti-spark - Go with a quality replacement. May seem to be expensive in the beginning; but buying a cheaper alternative will come back and be short-lived causing to replace it again prematurely. Would not want to do this job twice.
Petris Enterprise offers an upgraded quality component - which is already on my short list.

If you want to drain the block, you pull the knock sensors.
The reman water pumps come both ways...with or without the water neck and thermostat, so be sure to check when ordering.

The waterpump drive seal is very tricky. Requires a special installation tool. Check out these links. One has an alternative to the special tool.

This is what I do ..Had a 95 LT-1 run with the fount of the motor under water never went dead had to turn it off ,was blowing rater out the pipes like a pump.. How I do that first buy GM OPIT not cheep junk and open it up and use some very good sealer around the thing put it back togeather also seal the wires with water prof sealer and seal the the opit harness hole ,,then let your wife drive it in a ditch with 5 ft of water one block from your house . Water was over the fount of the motor and still running..Keep water out they will run...I was a good vet... Got to be smarter that what your working with..
