what does it mean I just got the car running again from having to change a leaking (water) timing cover gasket.I got it runnin yesterday and I took it out a few times and made sure that the water level was good(it was) but 2nite I took it out and dogged it a few good times and when I got home I popped the hood to make sure nothing was leaking and there wasn't but there's foam in the overflow resovoir.What does it mean?

 

detergants in the coolant, the recycled antifreeze whe use tends to do this alot a work.

 

so it's fine then I just need to make sure there's enough water in it tommorrow b4 I go to school

 

make sure it's a 50/50 mix of coolant and water
