i everyone. New to the site, first Hyundai, but I've been working on cars for 30 years so I'm pretty handy with a wrench. Bought this Elantra through carvana, it's got the 2.0 and runs like a top, super clean, but it just developed a coolant leak. After pulling the plastic cover I pressurized the system and right away saw coolant coming down directly above and to the right of the oil filter housing. I can't feel any coolant above the little shelf over the oil filter so it must be on the same level. First thought is water pump. Am I on the right track?? Thanks in advance.


You can see the coolant dripping in this pic

 

What you might consider,
If you spray some Brakekleen to help dry the area , then spray some talcum powder approx where you believe the leak is originating, then apply some pressure to the system and you should see pretty well the origin of the leak. Works most of the time.

Just like you need to use some pressure to see the leak origin , it is pretty difficult for anyone trying to speculate from a pix. Does sound like you are on the right path.

 

Thanks @hanky, did a little more checking and it looks like the coolant is coming from a hose that's behind and between the alternator and the intake, I think it's possibly from the t-stat housing.. From the looks of things it's missing a clamp. when cold the system held pressure fine, but with the engine warmed up it would start to leak..Hoping that's all it is. More puzzling is why the clamp would be missing.

 

Problem found, figured I'd close the loop on this. There's a coolant hose that's hidden by the alternator and right next to the intake. The previous owner must have had some work done. Anyway, the spring clamp on this particular hose was removed and left slid up the hose instead of in place at the base. Put the clamp back where it needed to be pressurized the system and all is good. Thanks.

 

Thanks for the update, always nice to hear when a problem is easily corrected,thanks.
