Are these lines normal or is something wrong?

Coolant line:


Line close to cab on right side when looking from the hood toward the bed (What is this line by the way?)

 

The first picture of the coolant tank isn't normal, but very common to have a leak there. I put a zip tie on mine to clamp it down and it still leaks. Not a big deal and haven't had to top it off yet.

The second pic I am not sure exactly what that is, but I don't have a leak on my truck. No marks at that hose.

 

I have no idea - I can go check my 2011 in a minute if nobody else knows.

As joes06tacoma said, the leak in the first picture is common. If you pull the tube off and look at the back side of the nylon that was inside of the tube, you will see and feel a very small ridge left from the seam in the mold during the molding process. Take a sharp knife and scrape just enough of that excess material off so that you cannot feel it anymore and then push rubber tube back in place. The ridge pushes out just enough on the rubber tube to allow antifreeze/coolant for a very slow leak.

 

I know what I am doing this weekend. Thanks!

 

I went to the dealer for my 15k Toyota Auto Care checkup today and was told that that it is the coolant overflow hose + fuel hose that showed residue. The tech insisted that nothing would be done to 'stop' the problem (re: shave the ridge on coolant), but they did clean up the hoses...

Then I asked why my 'estimate' noted "W/o LSD" when in fact I do have a Limited Slip Diff. He claimed it wasn't needed until 30k miles, then called later to say they did actually check it. Any clarification on this?

I kept track of my exact mileage before I left the truck and after; they drove it 1.5 miles. I have left my truck before for the regular service (this one Toyota was paying them $100 instead of $40) and they didn't drive that much. Supposedly they take 'every vehicle' on a drive. Is this true and why?

Naturally I have no problem if they take every vehicle on a drive and don't treat it like a rental car, but if this is unnecessary, I don't want them messing with my vehicle.

 

The LSD from 09 up is electronic (uses the brakes) and not mechanical. They do drive the cars, probably to "check" for problems.

 

The 2011s have electronic LSD programmed into the ABS system, rather than friction clutches in the differential itself.
