Could be a bad water pump or a leak in the line
I use a cheap plastic turkey baster that I bought at wallmart and suck the contents out of the coolant reservoir ( it doesn't take as long to do as I thought it would )
When your engine is cold add coolant to the coolant reservoir so it is up to the cold mark
Check the coolant reservoir in the engine compartment. There are marks to assist you with proper level. If it's empty you need to add coolant ASAP.
What I use on my engine coolant reservoir is a cheap plastic turkey baster from Wallmart ( it didn't take as long as I thought ) You should be able to empty the windshield washer fluid reservoir the same way
If you are talking about a vehicle, then the coolant level is critical for generating heat. Check you vehicle coolant reservoir if it is empty, wait until the engine is cool and check the level of coolant in the radiator and fill as recommended with the appropriate kind of coolant then fill the reservoir to the level indicated.
A pressurized coolant reservoir would have a thread on cap which acts as the " rad " cap
It would be on the coolant reservoir.
It cost me $185.00. That includes $85 for new reservoir tank and coolant & $100 labor.
Remove the coolant reservoir, flush it out, reinstall it and refill with proper coolant.
Either coolant is low or the sensor in the reservoir is stuck with dirt. Clean the reservoir with soap and water
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
