So I have a 2007 IS250 and recently got my water pump replaced at the dealership. Every now and then i would some coolant around the top of the reservoir near the cap area. I would clean it up only to find it again after a few days. My question is this normal and do you guys know what it could be?

 

it just means 1 or two things. they over filled the resevoir or the system still has air pockets pushing up on it. its nothing to be afraid about.

rinse with water thoroughly

 

As long as the coolant level is normal, you're ok. Its known to sweat a little at the cap to the reservior...
