[How to cool an engine?]

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?

[NO NAME?]

So, I added a few plugins such as essentials, But when I got to the server, I had no access to the commands. This is my name on tekkit <> I don't know why I don't have a name but it's really weird.

Is there anyway to fix this? thanks <3
