Leaking antifreeze

[packers15]

I have a 92 runner with the 3.0 4x4 auto with 192000 miles. Timing belt and water pump done 2000 miles ago. Lately after this thing has been parked I have been seeing a small puddle of antifreeze towards the rear of the engine towards the drivers side. I have looked at the hoses and can't really see anything leaking. It does not run hot and all other fluids look clean. Any idea's of where this might be coming from or what might be causing it ?

Hose!

It is a hose. Keep checking the back hoses on the back of the fire wall. One of them is leaking. It might be a small leak but it will get bigger. The space is tight so it will most likely be really hard to get the clamp off. It took me for ever and ripped the old hose to pieces but putting the new one was easy.

I tried to get to as many of hose clamps that I could and tighten them, still can't see were the leak is ? Doesn't do it all the time. Could it possibly be a head gasket ? It runs great, doesn't overheat, all fluids look clean and it is not blowing anything out the exhaust. Maybe a frost plug ?

Have you checked the oil cooler hoses. Also behind the intake at the firewall is a piece that the sensors connect to. That has a gasket that could be leaking. Its on the lower intake and has the coolant sensor and 2 others on it.

Drove it tonight, got it up to normal operating temp and then parked it. No leaks after sitting for over 3 hours. Will check after sitting all night, but this has got me stumped so far !

Think I may have found the culprit, saw a heater hose back by the firewall that was leaking a little and running down the hose. Still nothing on the floor this morning, so I am hoping that the hose was the problem.
