Default Coolant Tank - Leaking?
So I finished replacing my wiper motor's pulse board today, and right as I was closing the hood, I noticed orange goo on/around the coolant tank. You can see it in the pics below around the edge. What would cause this? I've cleaned the engine bay before so I know it must be a recent occurrence. The coolant has NOT been added to since then so it's not overspill. Any idea?

The leak seems to be coming from this hose connection point. It's like it's not tight enough. How would I tighten it?

Are you sure there is not a crack on the plastic nipple on the tank? That would be my guess.

If there's a crack on the nipple, could I use RTV silicone?

The tank on my 2001 was leaking in that exact spot. I just replaced mine instead of trying a repair. Good luck.

Mine was leaking there too. I push the hose as far as it would go and put a screw clamp on it.

Save buying another tank
