How to cool an engine?

[AcidRain]

So, I build a quarry. One time the combustion engine turned red and then exploded, Here is the way I tried to cool it. I pumped water and put it into a tank. And then used cobblestone waterproof pipes and connected it to the combustion engines, Not sure if i'm doing anything wrong.

How do I cool it if you can?

hey the only way to cool it down (well the only way i know) is to turn it off for a little then let it go to its orignal color and then turn it back on

you have to pump the water directly into the engine.

Combustion engines only produce 5 MJ/t, a generator hooked up to an energy link will produce 4 MJ/t. The total amount of energy generated is equal, and generators don't blow up. Sorry, but I can't help but ask why to use an engine to power a quarry in the first place.
