Coolant leak

[yeldogt]

Long time forum reader. First time I have had a problem I can't find an answer!

My 02 LE 4WD w/125k has a strange coolant leak that I can not find. I am getting a small drip from the passenger side of the truck - normally only noticeable in the morning on the coldest of nights. It looks to be dripping off of maybe the rear of the lower control arm -- its hard to tell since it is such a small amount -- the coolant bottle is still at the max line. I see the heater hoses going into the firewall on that side -- I guess to the heater core -- felt all around them .. but did not feel or see anything wet. I had this looked at a few months ago when I noticed a spot of oil - and also smelled some coolant -- my mechanic fixed the "o" rings in the cooler (fixed the leak) and he looked around for any coolant leak -- and could find none.

I wanted to know if the engine has any hoses or coolant lines behind the engine against the firewall that could be leaking?

This truck has been incredibly reliable -- I did replace the struts and shocks this year as well as the exhaust.

Yes, there's a coolant line between engine and firewall. And the coolant temp sensors are back there. And that line is a bear
to get to.
