Problem is, Kevin, that I can't see where it's leaking from - just a trickle down the front of the block. It leaks when cold and engine off but I'm not sure if it leaks when hot and running. Perhaps it does but evaporates quickly.KevinC said:Depends on the condition of your car and how long you plan to keep driving it.
If your car is on a low budget/minimum maintenance and you do not plan on keeping it too much longer the stop leak products are great and will work for moderate leaks.
Otherwise you may be concerned that the stop leak might create problems elsewhere in your cooling system, and just change the leaking component for a new or junkyard replacement.

Don't use rad-weld or any other 'stop-leak' quick fix thing.
It can cause big problems elsewhere in the system, particularly the water pump.
The Saab cooling system is relatively simple with few pipes, most of which have easy access.
Easiest way to find a leak is to, on a dry day, slide a large sheet of cardboard between the front wheels and let the engine run for a good long while. If you have aircon, switch to 'econ' mode and set the temp to 'lo'.
This ensures the minimum engine cooling is applied.
A leak should present itself relatively quickly, however it may also take some time before it shows.
