Well, I filled up the overflow tank a couple days ago, only drove about 40 miles, and noticed this afternoon that the tank was completely dry and the radiator was only about half full.

I topped off the radiator and noticed right away that it was dripping from the front of the engine. I took it for a short drive and noticed that it was leaking a lot once it warmed up a bit. Once again from the front of the engine.

It is dripping mostly from between the crank pulley and the block with some more dripping from the smog pump's lower mounting bracket. Note: I said it is dripping from these points, not that it is leaking from them.

I can't see where it is leaking from and it doesn't help that the entire underside is covered in coolant from driving the car. My first guess is the water pump, but it looks like the drip hole is on top and dry, but is there maybe another one underneath the pump?

Does anyone else have any ideas what the likely issue is? I'm not too keen on spending a bunch of time sitting in an icy puddle in the middle of a snowstorm trying to find this leak...

sounds like the water pump is leaking from the weep hole.

replace the water pump, T/stat and hoses.

That was a thought of mine, but I think the weep hole on my water pump is on top and is perfectly dry. Might there be another one underneath? I can't see in there to tell...

You'll see it when you take it off to put the new pump on.

Yes there are 2 weep holes. one on top, one on bottom.
Take a telescoping inspection mirror and see if the bottom hole is wet and/or has a crusty stain.

water pump is the most likely source of the the leak, however it could be the intake manifold gasket leaking, thermostat gasket and/or water outlet leaking, upper radiator hose or any of the heater/by-pass hoses in the area.

if the bottom weep hole, on the water pump, is dry. rent a cooling system pressure tester, pressurize the cooling system and start checking/inspecting for leaks.

Ahem. There's a writeup in the archive section about waterpump replacement.

regarding the AC compressor bracket bolts..... there are 2, one at the top and one in the middle. these are 2 entirely different bolts. DO NOT interchange them.

What 88grandmarq said. Keep close track of what bolts come out of where. You've got to pull just about everything off the front of the engine to get to the water pump. It's not all that hard, just labor intensive. Take your time and do it right.

The hardest part is scraping all the old gasket material off. If you don't do a good job of this, you could end up with a brand new leak and you'll have to do the job all over again.

'k, thanks. We'll see how it goes. I'll probably spend today prepping and start taking it all apart. Then pick up the parts tomorrow, and spend Wed and Thur putting it all back together...hopefully.

I'm also planning on doing the intake manifold gasket (because I know it has a leak) and the PCV, valve cover, and valve seal gaskets, since I'm going to have the whole thing apart anyway...

The water pump is a separate job, only needed the front end off (radiator can stay, just keep it protected).

But by all means, do the intake/valve cover job at one time!

I've got another quick question for you guys. I'm thinking of replacing a few of the valve seals, because I have noticed some oil on one of the spark plugs and some ash in a couple others. Is it all right to just replace those few seals or should I replace them all?

It's not any harder to replace them all, it just takes much longer...

It requires some speciality tools to be able to replace valve stem seals with the cyl head still mounted on the engine.
If they arent leaking terribly, leave it alone or pull the cylinder head.

Or get the special tools!
Unless you can make them or cheaply get someone else to make them, they're worth it.
Oh how I love special tools.

According to my manual it will only take a compressed air adapter for the spark plug holes (to hold the valves in place after removing the keepers) and a valve spring compressor, which hopefully won't be too expensive, or I can borrow it from the parts store.

I'm gonna pull the plugs today and see just how much oil is in that cylinder...

It gets rather tricky. First you need to do cylinder leak down test to make sure the cylinder(s) will hold air pressure while you are working. you also need pressuure regulator to be able to adjust the air pressure, too much air pressure can damaged seals, too little air pressure and the valves wont stay up.

Obviously if you pull the valves apart and the cylinder won't hold air pressure or you loose air pressure suddenly/unexpectedly, the valve(s) fall into the cylinder and you can't reassemble it. Then you are forced to pull the head.
