On my nissan pickup It was leaking coolent
So I did the old trick when you take the coolent cap half way off
So pressure does not build up and that helps it not leak.
But when I did this I was looking at
The scan gauge and it seemed that I got better mpg but I want to
Ask if any one has done this?

Most cooling systems are 13 to 16 psi so maybe if your not makeing it build up pressure it will lighten the load on the motor? Or so I think
