Coolant Change
Is it possible to use the pink G12 coolant in my 85 cabriolet if I completely flush the old green coolant, is there any compatability issues that I should be aware of?

Good question,
But I have to ask why. at more than $30 for a 4l jug, I think it is a little too expensive.
I would say to use any name brand antifreeze. But the light coloured (yellow) is the best. (you cn tell when it is dirty.)
I would suggest to do the following.
Drain the cooling system,
Remove the thermostat and replace the housing.
Disconnect both the top and bottom hoses from the rad,
flush the system, (prefferably with high pressure water),
Remove the thermostat housing and install a new thermostat,
Reconnect the rad hoses.
Mix the antifreeze with water to obtain your desired freezing level (In Calgary I highly recommend -40 Degrees). This is important especially if you plan to drive the car in the winter. Even if you don't, wou don't want the cooling system to freeze.
Fill the cooling system and ensure the cap is on tight, and
Finally run the engine allow the car to warm up. You are looking for two things here. 1, to ensure that the cooling fan will turn on at an appropriate temperature and 2, That the thermostat will open when the engine is warm.
It is important to have antifreeze in your cooling system all year round because it is also the lubricant for the water pump.
