Antifreeze smell
Yesturday, I went to go to work and as soon as I got in the 4runner I smelled antifreeze. The front and rear carpet are bone dry and the smell wasn't coming from the vent. The radiator is full and the overflow was not full nor empty. Does anyone know what else I should check?? Thanks

Have a pressure check ran on the radiator. Could be a tiny pinhole leak. They can be hard to find. If there is a leak the pressure will run off and show on the gauge.

Use a mechanics mirror and a flash light looking for the tell-tale red or green crust from the leak. Also, check carefully at the head block interface. Could be a small external seep through the head gasket.
