I've been losing about a liter of antifreeze every two weeks. Nothing found on the ground. Notices a small amount of antifreeze under the black intake plenum where it connects to the engine. Checked the water pump, thermstat and temp sending unit and can find no leaks. Where is this antifreeze coming from?????? No other areas show any antifreeeze i.e. where the antifreeze might be slung in dripped on the fan or drive belt.
any help would be appreciated.

Well if you see the coolant under the intake look there. Thermostat housing leaking? Upper Rad hose leaking when cold and boiling off when run for a short time? Easiest way is to pressure test it when cold and hot. Maybe try to borrow a Pressure tester from a buddy or shop that might be willing.

 

thanks. Will look at getting a pressure tester.
I can't find any antifreeze ANYWHERE on the engine except under that plenum
