Coolant leak

I saw this last night when I took my skid plate off. I don’t know how long it’s been doing this but I checked the reservoir, radiator & they were both full. Do you think it’ll get worse? What you guys think?

 

Will get worse, but its just the radiator, so no big deal.

 

Wash it off and see if it reappears. Could have just burped some coolant out the overflow. If it reappears and you are under warranty, back to Toyota. It appears to be along the seam between the core and the reservoir part of the radiator. My jeep had its radiator replaced for the same reason. Not real common, but stuff happens

 

How far up does the leak go? It looks like its running down to that point and not actually leaking there.

 

Check the front of the radiator for road debris damage.

 

Check overflow hose connections on both ends and the bottle.

 

Based on the pooling of coolant in the first pic and your observation the coolant level is not low, this is a recent occurrence. Looks like a bad seal on the radiator, but do a radiator pressure check to confirm.

 

Does look new condition. Can’t hurt to check closely for leaks.

 

had something almost identical on my prior truck (not a tacoma) at about 60K miles, a coolant leak at the seam. i replaced the radiator.

 

Ended up needing a new one & was able to get a OEM. Set me back only $330 for everything. My mechanic use to work at Toyota & got me deal. I got lucky.
