How to Fix a Cracked Coolant Reservoir

If your car’s coolant reservoir is cracked, the coolant will not be able to circulate and it will eventually cause a problem. There are a few things that you can do to try and fix the crack:

1. If the crack is small, you can try to pour boiling water into the reservoir and wait 10 minutes. This will expand the crack and make it easier to seal with hot glue.

2. If the crack is larger, you will need to replace the entire reservoir.


If you’re experiencing a problem with your coolant reservoir, there are a few things you can do to fix it. First, make sure the reservoir is full of coolant. If it’s not, add enough coolant until the reservoir is full. Next, check to see if any of the hoses connected to the reservoir are kinked or twisted. If they are, untwist them and try tightening them up using a wrench. Finally, inspect all of the connectors on the cooling system for any corrosion or wear and replace them if necessary. Once these steps have been taken, your chances of fixing the issue will be much higher.
