Possible Coolant Leak?

2016 with 64K.....20 min drive into work and I get a warning as the engine temp shot to red......check the coolant reservoir and it's empty. Filled with water and drove home.....no issue and the reservoir is full hours later. Noticed two spots in the driveway.....above the pink stains I see this......it's about even with the front of the front doors......any ideas???

 

That's the oil cooler...but typically with a slow leak (that's not visually wet and dripping)...you'll see crystalized deposits...which I'm not seeing there.

When is the last time you checked your coolant?

 

Maybe 2 weeks ago and it was fine......also only had the truck a couple months and when running the heater it takes forever to get to temp.....is that a sign as well?

 

Look higher, the famous coolant cross pipe drips down in that direction.

try this for reference of the bypass pipe

 

looks like that's what it is......not a lot but there is pink residue. How much am I looking at for this?

 

Trans or the engine needs to come out. There are a few threads on this that will get you some more info.

Be sure to get this upgraded piece, not the plastic piece.
