Good afternoon! I've a 2000 Chevy Monte Carlo, L.S. 113K miles, 3.4 engine. I'm finding small puddles of anti-freeze (coolant) sitting on top of frame below the crosspipe. I can't seem to find where this coolant is coming from but it's isn't the thermostat housing. Has anyone else experience this problem with coolant leak in this area? If so, where did you find the leak? The leak seems to be intermittent! The engine hasn't ran hot and low coolant light hasn't appeared yet. Thanks!
