Hi guys,

I got a 2005 v6 coupe. I'm no car expert but I'll try to explain the best I can.
On top of the coolant tank, there is a small black hose that leads out to the radiator area. Where the tank and the hose meet, I see what appears to be dried up coolant crusted up all around that area. My coolant level is pretty stable so its not a huge issue, but I wanna fix it. Is there possibly some sealant I could apply to the area?

Thanks!

 

You'll need that little plastic fitting to spin, allowing you to unscrew the reservoir cap. Plus, there should be a small vent hole in the cap. Clean it up & see if it comes back.
Normally the proper level is far enough down in the reservoir, so it can expand with heat & still not spill out the top with normal driving & shaking.
