Overheating
Hey guys I own a 2007 Lexus GS350 (3rd gen). I had my motor completely rebuilt from top to bottom. Has about 3500 miles on it now. It’s got a new thermostat, radiator, radiator hose and cap, not a new water pump though. It recently started to over heat a bit though. I let it cool down and noticed it was low on coolant and checkef under the car and saw no leak. My reservoir tank got full to the top and it leaks it out now and I constantly have to be adding coolant now before driving. What can it be.
