Thank you all for the feedback. I suppose I have the 'classic' story that maybe someone else can learn from.

There was intermittant heating problems, only on inclines, and never RED LINE. Then, while on a road trip it did RED LINE, and this situation became constant. Stuck in a distant town, I took it to a shop, asking them to test for HG leaks. They did the pressure and leakdown test ($130). Like someone above said, nothing showed up.

I decided to invest $2000 in a new radiator, waterpump, hoses, timing belt and a few other items. When I picked up the car,it ran fine for about 2 hours, and then went right back to the same problem. Now I can't drive it 25 miles without it overheating.

Now where I am screwed, is the shop says to have it towed back 160 miles away). Maybe the HG is reasonablething to replace, but what if it is a CRACKED BLOCK?

The moral of the story - if you love your svx, then don't mess around with cooling problems. Fix it now!

Thanks again... I will post the result of this saga in a couple days...
