Having had the chains etc done recently, the garage had put ordinary antifreeze in. So I thought I would change it for some proper stuff. However, I then noticed a small puddle on the garage floor. It looked like a leak from the nearside of the radiator. Anyway, I toddled along to the dealer, who said that Saab had recently introduced "Longlife" antifreeze, that allegedly never needs changing (at least until a hose bursts!!!). So I bought a bunch of the lovely pink stuff, and after multiple engine flushes to get rid of the old stuff (the last couple of flushes being with soft water collected from the dehumidifier), I added the 4.5 litres of antifreeze, topped up with soft water, and went for a spin.
Now, after a few more uses, I can see no sign of a leak.
So does anyone know if the new Longlife coolant contains one of those smart long chain polymer types of leak sealant, or am I just being hopelessly optimistic and the leak will return by Thursday?
