Coolant leak
I tried a search about this but am just going in circles. A few weeks ago i replaced the water pump and hoses. It was leaking out the bottom. The new pump is fine, but today I have a coolant leak from somewhere below the drivers side head, towards the front. Could that be the block heater? What is involved in fixing it? Or is there something else I should be looking at?

There are 2 small lines in the area that is leaking. I didn't have a light when I looked earlier and now it is raining. If I am not mistaken I think the lines turned toward the back. I didn't see where they went. Are they to the oil cooler?

The oil cooler is a large tube, about 2.5-3" diameter that runs from the front to the back. I'm trying to think of lines that are in that area...only thing I can think of is the fuel lines right now.

I will have to get under there and look closer. Is there a bracket at the back too? Does it leak where the bracket meets the block?

Yes there are flanges on both ends that mount to the front cover and the block, it also houses your oil filter.
Here is a rebuilt kit, if it's your issue.

Coolant leak is really diesel
Well it seems like I did not pay attention to what I was looking at. When the water pump went bad I dumped all the coolant and put in new. I had this big container of greenish old coolant. When I looked for my leak I saw the same greenish drip and thought it was coolant. Today it stopped raining so I went under the truck and sprayed it down with some cleaner. After it dried off I started it up and it was still dripping green in the front off the larger of the 2 fuel lines. But I put my hand under it and then smelled it. Diesel fuel. It is coming from the joint in the line, I assume it is the supply line since it is bigger. So what is the deal with this? New line? Are there any seals in the joint?
