Yes, under normal circumstances you should not have to top off the coolant. If you are using Porsche coolant it leaves a white residue to help identify the leak. The most common issues are a bad coolant cap or cracked tank. Feel around under the carpet in the trunk, and pry the plastic cover under the cap off and check the bleeder valve. Also, if you have already topped up with 16oz of water you may want to start using a 50/50 mix. However, if you do not know what is in the system do not add a random coolant, mixing different coolants can cause them to congeal.

Ok. I will take another look. Last check, the carpet was good a dry.

I have no idea what type of coolant was used before I added simple water. Maybe the maintenance records will show, but otherwise, no such luck knowing.

You definitely have a leak somewhere and you probably need to find it before it gets critical and trashes your motor. Also, distilled water is recommended instead of regular tap water . The minerals in tap water will cause galvanic corrosion in your cooling system which will become a nasty future problem.

Good luck!

Hi.

I looked again closely at the carpet and trunk. Everything looks really good. But....I did notice that the "cup" section that the water cap and oil cap sit is often just a little wet. Plus the coolant cap is often a little wet too. AND, the cap was replaced way back in 2004 because the owner was complaining about the hot temp coolant light was going on. So, the dealer replaced the cap. My cap ends in 02. So, I'd say that's my first step here right? Change the cap to a newer version ending in 04?

Thoughts?

Change the cap, get a pressure test done, and flush the rads. Then get a proper coolant mix in there and you are good to go.
