Car using a gallon of water per day Sign In

2006 Suzuki Forenza 147,000 miles unsure of motor size.
My car gets hot its registers about half way on the temp gauge and heater wont work. When we fill up the reservior with water it uses it and the heater starts working no visable leaks. Uses about a gallon per day

You need to pressure test it to find the leak. I hope you aren't using straight water. I can see it would be expensive to jump coolant in it every day, but you will cause other expensive problems running on just water.

Ditto - do not use plain water unless you are stuck in nowhere and your life is a stake from some stream to get going again. A gallon a day will be found, trust me and the sooner the better no matter what or why it's losing that much. THAT'S A LOT!

If it's using a gallon a day it's going somewhere and you need to find it. As Nick suggested, you really need to pressure test it. If you don't have a pressure tester most parts stores have a loaner program. You just put a deposit down and get that back when you return the tool. My local Carquest loans tools and all they need is a name and phone number.

Since it's losing a gallon a day I would think that with the vehicle running you would be able to see where it's leaking. What I always did before I got a pressure tester is jack the vehicle up and look up top and underneath. I'd also check the ground and that would sometimes give me a general idea of where to look. That doesn't always work because since the cooling system is under pressure it can spray from one area and reach the other side of the engine compartment. If you do check with the engine running be careful. Use jack stands if lifting the vehicle, watch for moving parts such as fans and belts, and watch for exhaust. Double check to make sure the vehicle is supported properly and make sure the emergency brake is on.

They also make a dye you can add to the cooling system. You then use a black light in order for the dye to really light up. You can get the dye and light in a kit for about $25.
