Yes
Remove the coolant reservoir, flush it out, reinstall it and refill with proper coolant.
The coolant reservoir on the MK3 jetta is located against the firewall. It is a small round reservoir.
Yes- coolant reservoir is designed to accept excess coolant - As coolant heats up it will expand and flow to the coolant recovery tank (reservoir) and as it cools (contracts) it will be sucked back into the radiator
Reservoir light? You mean low coolant light. Low coolant level means the reservoir is low of coolant.
After you have completed work on the cooling system and you begin to replace the coolant, open the bleeder a couple turns. As you pour coolant into the reservoir air trapped will escape out the bleeder. As soon as you see coolant come out of the bleeder close the bleeder valve and continue to add coolant to the reservoir until you have reached the full mark. Replace cap on reservoir. Allow vehicle to run through a drive cycle and cool down. Top off reservoir to full mark if necessary.

Coolant is used to keep an engine in a vehicle at a temperature safe for operation. If no coolant is in the reservoir, an engine will not start.
The amount of coolant it will take to fill your vehicle is dependent upon how low the coolant level is. You can add coolant to your coolant reservoir. The reservoir will have an indicator of when the coolant system is full.
