My 88 GT 2.8L has had a very slow coolant leak for a while. Now when the car is running I can see a very steady drip coming from under the car. I got under it and tried to locate it and took some pics. I was initially thinking the water pump went bad even though I replaced it 1.5 years ago and it only has 5,000 miles on it. By the looks of the leak I'm thinking it isn't the water pump. From underneath the car the dripping is coming from between oil filter and the A/C compressor. I couldn't tell if what it was dripping off of was the rear manifold or a hose. It is directly under the second bolt that goes into the manifold. Thoughts on what it could be? It only leaks when running. Thanks!

It might be your gasket between the timing cover and the block. When you change the pump if you don't keep the timing cover tight since the WP bolts are part of what holds it tight you can cause the gasket to start leaking.

A common place is right behind the large coolant hose (from the radiator ) coming off the water pump. The gasket between the block and timing cover gets very narrow there and can be a place it leaks. It's hard to spot but you will often find the back side of the large coolant hose wet because the coolant will leak out and run down the coolant hose then drip off on the AC and other area.

Ayup, you can get the dye and light cheap enough and it will save you a lot of time.

That area?
WP, Timing Cover or hose? Maybe.
Can have freeze plug or head gasket is bad.

Try the dye as above.

Thanks for the replies! I guess I'll give the die a shot this coming weekend and hopefully have everything in check soon.
