Thread: Antifreeze on the passenger side of the engine block

Commom leaks are coolant elbows or the water pump is leaking.

Hard to say over the net with no pictures and I'm not there in person.

This, they tend to crack and leak or they just blow the **** out and dump coolant everywhere and the motor can overheat.

Could be a loose hose too, I had that problem a few weeks ago where I was mysteriously loosing coolant. Turns out the lower hose from the engine block had worked loose somehow. I loosened the screw, gave it a good shove, and tightened it again, problem solved.

But as others say, the most likely suspects is a water pump or a coolant elbow.
