Is it hard to change the core?

Any ideas on how to fix the right 3 gauges?

I've checked all the grounds and cleaned them as needed for the last 12 years of owning the car.

short of replacing the gauges I think I've done all I could to make them work but no dice.

Do you have a cluster you can part out, I just need the right 3 gauges board

You may not have a leaking heater core. If it was leaking to any significant degree, you would have a fogged windshield. Before committing to changing the core, it would be well worth your time to remove the heater hoses from the tensioner assembly and run a pressure test to see if the core is really leaking. Although some have replaced them without removing the dash, they are not easy to change.

When you get around to changing the thermostat, and hopefully flushing the Dex for "mixes with any color" coolant, use this re-fill procedure to minimize air voids in your engine: http://www.bonnevilleclub.com/forum/...=article&k=100

Question, on the right side of the picture, the circle at the outlet of the water pump, are you to look for a leak at the hose (where connected to the water pump) or is there something behind it that can leak too? Thanks

That circle just indicates the potential for a leak at the lower radiator hose to the water pump inlet connection.

Brand doesn't matter - just be sure the label says "mixes with any type, any color." I use Wal-Mart'* house brand - "Tech" I think. Sometimes I use O'Reilly'*, sometimes Prestone.
