Coolant is leaking from my reservior tank; I wanted to know if there was a quick fix as I will not be able to get it repaired until the end of the week. Any help here will be greatly appreciated.

If the tank is part of the pressurized section of the system you can use a brand name "stop leak" and see if that will help. It's available at most auto parts stores. Follow the directions on the container!

If the tank is made of plastic and only holds the excess coolant in a non-presurized container you can probably go a few days and just check the radiator daily when it cold.

Okay, thanks. Not sure which it is but will find out. Thanks, again!!

I should have mentioned the easy way for the novice to tell the difference.

The pressurized tank will have a radiator cap on it that is spring loaded in some fashion. (spring holds the pressure) A non-pressurized "holding tank" will usually have a plastic cap that is screwed on.

Okay, so I have the non-pressurized type. I have to screw the cap on and it clicks as I turn it. Good to know becuase I was on my way to get the Stop Leak. I have a Jaguar S Type and the reservoir sits right in the front there is no additional jug-like coolant tank off to the side unlike my Kia which has a separate coolant reservoir apart from the radiator.

Thanks so much for your help.
