I just did a coolant flush and I put about 13 qts. I know other manuals say about 24 quarts. I did a coolant flush with a garden hose too. so my block may have been full of water too. I added a little concentrated coolant to ofset this though.

The concentration of antifreeze in the coolant needs to be checked prior to the onset of cold weather. A 50/50 mixture of antifreeze and water is recommended and will protect against freezing down to -34 degrees F and boilover protection to 263 degrees F.

For maximum protection, up to a 70% mixture of antifreeze can be used for freezing protection to -84 degrees F.

Noth: Do not use more than 70% antifreeze, and never run straight water in the cooling system because it offers no corrosion, freezing or boilover protection.

Pick up a prestone coolant/antifreeze tester and that should help you get your Coolant mixture right.

Diesel engines use about 25 qts., not any gas engine


If you put 13 qts of coolant in, you are nearly at 100%, big time problem. Anti-Freeze/coolant are design to be diluted with water and will not function at 100%.
Also note, some of these newer vehicles can't be flushed correctly just using a garden hose. Not sure about the 2003 though. You could create an air pocket in the system that could be extremely difficult to eliminate.
