Default Coolant leak right above the front side of the oil pan?

Is this a water pump issue?

Default Likely, I just went through this. In my case, it was very minor and I held out

until it was time to do the t-belt.

Default It is coming out a lot. Only when the car is cold, not when it was running or after shutdown.

I squeeze the upper hose to the res and hit seem to start to come out a lot.

Default its basically the same as doing a timing belt job. I suppose you could save time

by not removing the crank pulley and re-using the t-belt.

SJM's site has good advice and pictures.<ul><li><a href="http://www.sjmautotechnik.com/trouble_shooting/S4timing.htm">http://www.sjmautotechnik.com/trouble_shooting/S4timing.htm</a</li></ul>

Default No but there used to be a good left up. Been deleted. (edit)

Sorry, it was just there and I am too weak (to resist).

Like Sean says, the only way to the water pump is the same amount of work to get to the timing belt. Most people do the water pump when they do the timing belt. Avoid water pumps with plastic parts, e.g. Graf. You want all metal German built, like Hepu.

Default If the water pump bearing/seal is bad then you better also replace the tensioner and idler

They all tend to have about the same life. And as long as you are in there doing all that the T-belt is only another $30. If you don't do all this you will be crying when the next thing goes and half of your valves are bent.

Default I heard broken TB = bent valves is a myth.

Wait. I thought Hepu was the *only* metal-impeller WP for C4s?

My bad: Graf = plastic impeller. Hepu = metal impeller.
