Having some interesting leaks on my 06 LX. I think everything is normal but thought I would put this out there for advice.
Background - newer radiator. New radiator cap. New fan clutch. Unsure on thermostat (probably changed when radiator was changed - both prior to my ownership). Until a few days ago, no leaks and constant coolant level.
Took my truck to the dealership for recall notice. Pick tuck up and see that they performed 'safety check' and probably topped off fluids. Truck drove normal, no issues. Early the next morning, I drove to Asheville, NC from Atlanta and back (about 425 miles round trip). It was quite cold in Asheville and drove through snow/ice. Again, no issues.
Yesterday, my leak starts. Came out in the morning - no fluid on ground. Started truck, let it warm up, turned on rear heater for my son. Initially, air will blow hot when set at approx. 75, then will cool down. Understandable as the auto climate is working. When truck was warm, I had to turn temp up to about 80-85 to get actual hot air to blow. When it blew hot, it was damn hot.
Anyhow, got to work and noticed a puddle (about 6 inches across) under truck. Looked like anti freeze to me. Popped my hood and the overflow bottle was sitting above full (this was when truck was cold). Thinking that the dealership over filled, I decided to keep my eye on it and drive home. This morning, no leaks, no puddle. I thought all was well. Parked after driving my son to school (and turning on the rear heat) and found another, similar puddle.
It still looks to me that there is too much coolant in the reservoir. Hard part is that I can't verify whether the dealership added too much or none at all. Also, only seems to leak when I run the rear heat. Running heat without rear does not produce a leak. Before taking in for recall, I never leaked when running the rear heat. Leak is dripping off of the hose that runs from bottom of radiator to top of engine block. But it could easily be dripping from above and traveling down hose before dripping off.
Hooked my ultragauge up this morning. Truck got up to temp pretty fast (in about 2-3 minutes of normal driving). After that, it held 190-195.8 the whole drive. Had it up to 75 mph and then stopped at a light. Ambient temp was about 45 degrees.
Anyhow, really long question but does any of this seem normal? Like I have too much coolant and the overflow will sort it out? Or is this indicative of another problem? What is normal operating temps on these rigs?
Many thanks!
