2021 coolant leak

I noticed a small coolant leak, few drops on my garage floor recently. Any ideas or insight would be helpful before bringing it to the shop. Leaking coming from passenger side toward the back of engine/transmission area (could be further ahead running back when driving)

 

I'd be taking a look up top by the firewall (at the top of those warming puck hardlines) for the source. It looks to me like it is starting higher than these photos, specifically because the last photo seems to show the stream starting higher than the puck/hoses and running down the bell housing (up by the O2 sensor wiring)

 

I hope I'm wrong and it's a simple fix for OP, but it sounds likely to be a valley plate leak -

yep, probably valley leak. How many miles?

 

56,857 miles

 

:/ Any chance you have an extended warranty?

 

I do not unfortunately. This is my 2nd tundra and never had any issues until now.

 

Isn't drivetrain warranty on 2021's 5 years/60k? Might not need extended warranty to get it covered as a warranty issue.

 

Check up higher on the bell housing for trails. Just resealed my coolant valley plate, been leaking for awhile.. 2016, 116,000 miles. https://youtu.be/IU14pWnVObc?si=5bAiy1-K25a-KIDU

 

Another vote for valley plate leak

 

Let's hope so or I'll try fight for it. Our local dealership was bought out by another within the past year or so. Haven't had to deal with new owners yet with service so hopefully all goes well.

 

If you're really going that route, you would be wise to fight for a new plate too. Good luck
