losing coolant

I have a 2012 tundra and for some reason the coolant level in the overflow drops. I have checked the hoses and the radiator and don't see any leaks. Is there something I am over looking?

 

Check water pump? Make sure it's not leaking?

 

If you have pink fluid under your vehicle you have a leak. I could not see where my leak was coming from. Went to dealer, he says water pump replacement will cost $1038.00 plus flush and fill of $139.99. 2013 Tundra 4.6L.

 

I didn't let them do it for that price. I went to another Toyota dealer in the Atlanta area 7 miles away and got it done for $603.00. Ended up at Rick Hendrick in Sandy Springs. Marietta Toyota gave me the ripoff price. I try to let Toyota dealers do the work because I travel so much and they can back up each other, independents don't do that if I get 200 miles down the road and start leaking again. I'm warning people about Marietta Toyota.
