I am losing coolant and I cant find were it is leaking. I wasnt having any problems before replacing the belt tenchiner. There are no visable leaks but on a two hour drive the over flow bottle is empty. Maybe a preassure test I dont know. But with hood up and car running still see now leaks cheaking everywere I can see and even lloking at the block I no smoke either. Please help thanks for looking

Are you checking the radiator, or just the overflo bottle? When it cools, check the radiator, fill it, and thrn top off the overflo bottle to the cold mark. If there is air in the system, as it dissipates the pressurized system will suck extra coolant needed from the overflo bottle - maybe you just are a little low. The level will vary in the overflo bottle as well, depending on the pressure in the system.
