    I have a 98 gt pure stock. Recently had my water pump go out, had it replaced, then had it flushed, the mechanic was concerned saying it was still running on the hot side, drained and filled it then he said it leveled out to 210 or below. I've been closely monitoring my temps and it's staying around 195-210 (95° and higher temps in Texas) I still think that's a lil hot? Plus my over flow reservoir stays low (is that normal) is all of this normal? The car has 170+k miles one it.

    Pretty normal for a stock car. If you want it to run cooler you could get a 180* thermostat and tune for it.

    Stock thermostat is 195, so car runs at around 195-205, who woulda ever thought that would happen.

    The car is fine, wouldnt think twice about.

    Bottom side of the water pump.

    When the pump fails internally it can start to leak and the weep hole lets the coolant out.

    as I said I have had my water pump replaced, coolant system flushed, lower and upper intake gaskets replaced. Last night I was at the store and she decided to "pee" all over the ground, she never ran completely hot, once I started driving the temp would slowly drop down to just above 210, once I got home popped the Hood and heard hissing and spewing on the passenger side of the engine above the water pump. Here are a couple of photos, a friend of my said it's the 2 elbows attached to the tensioner pulley.

    It seems like you did not replace your elbow fittings!

    When you did the water pump you need to put in new elbow fittings there soooo cheap!

    OK I bought the elbow fittings and looked up a vid on YouTube http://www.youtube.com/watch?v=QldgV...e_gdata_player In the video his tensioner assembly needed 2 plastic fitting, mine doesn't, only the one going to the intake is plastic. And that sucker was not easy to get it, it took some exercise. Here are pic of mine front and back.
    Remove the belt, remove the alternator, remove the 4 bolts holding the tensioner assembly on, and pop it off, change the elbows, put it back together, the bolts will pull it all together so alternate when tightening.



    *sorry pics are sideways

    You didn't replace the o ring on the lower one? You'll be pulling it back apart soon then.

    Nope didn't know the one on the plastic one would fit, I would have had to cut the old one off and woulda been pissed if didn't have a replacement . I had no way to the part store, I had the car in peices, I'll deal with then. At least I will know exactly where the problem is.

    I reused a couple times. There's a chance it won't mess you up. If so.. just pull again and toss that ring on the lower.

    One note here for anyone searching in the future. 97/98 should be handled with care. If you put the wrong force (pulling) on that lower elbow you can break the timing cover where the elbow goes into it. Then you have bigger issue.
    I drink..so consider that when reading my posts.
