I'm not sure why my '30 is using so much water. I just had the radiator boiled out and a leak repaired. The radiator has been pressure tested and is in good shape. I installed a new water pump and ground the impeller back about 1/16'' because it was splashing water out of the filler. Now it doesn't and I can feel the water circulate when I put my finger in the radiator. The motor runs well and the water temp gauge is always in the normal (green). I placed a rag by the overflow outlet after driving for about 10 miles and it was wet, so I guess I'm losing the water through the overflow. I lose about 1/2 gal. during a 20 min. drive. Should I grind more off of the impeller? I'm not too concerned yet because it doesn't overheat, but I think it just a matter of time on longer drives with losing that much coolant. I have been using "Water Wetter" and distilled water as the coolant. Any suggestions?
