Default Coolant overflow reservoir Tank Replacement.

Where is the best place to purchase a replacement reservoir tank that includes the sensor? Have issues locating replacement.

You could try a Chevy dealership, but it may be discontinued. Otherwise try a corvette salvage yard or find someone who is parting out a C-5 corvette. E-bay is always a good choice too, either NOS or used.

I found a NOS GM reservoir on ebay earlier this year, so I second this idea. Obviously only works if somebody has one they're selling that way...

Hit or miss quality with Dorman......and not applicable for the OP given they have a 99 with a coolant level sensor.

I would just tie the wires together and be done with the sensor.

I've had a Dorman on my 2002 for ~10 years. It doesn't leak so I guess it's fine. While I usually don't encourage disabling sensors, that might be the move here.

Summit does have some of the Moroso sheetmetal ones in stock, but those don't work with the sensor off the shelf.

It's probably easier to adapt a sensor bung to the metal one than plastic
