Running at 95 - 97 deg once oil temp up at 60+.

In the last 6 months I've topped up the coolant reservoir (up to half way) to the extent that I've now finished a 1l bottle of the blue stuff, having covered about 900 miles.

Can't see any signs of leakage in the garage after a run, no steam during a run, or in the engine bay area yet I need to top-up after every run as the water is scarcely covering the bottom of the reservoir.

Is she running too hot, where the blazes is the coolant going, any maintenance routine I can do to address this?

Any ideas appreciated.

Cheers - will give that a try (found the screw you mean earlier) tomorrow. Crossing fingers that it's not HGF time.

Cheers guys - yes perhaps it is just a case of overfilling. Absolutely no signs of seepage around the radiator. 1cm above the base of the expansion tank. Fans kicking in at 92 and 96. Just seems a bit hot and odd that the 'excess' I'm putting in doesn't show itself as it's expelled.

I'll stop worrying quite so much I think as it's sounding like another TADTS.

I had a similar concern. Was constantly topping up - not much, but enough to cause some head scratching.
One particular evening I heard a hiss as I pulled onto my drive at home. On investigation, (not easy with the Tuscan!! just had the main bonnet propped on some wood)I saw a damp patch around the heater pipes. Aha! I thought - get some new pipe & clips - job done!
Wrong! - later, still having to top up coolant, I repeated the above exercise.....and realised the heater matrix was leaking - and must have been getting progressively worse over a fairly lengthy period. In the early stages the leak was simply being evaporated by the heat off the exhaust manifold/pipes.

None of the usual suppliers could get a replacement. In the end I took the matrix to a local radiator specialist, who recored it for £90 all in. Coolant level now rock steady - joy!

Happy to say that the level stayed constant at the weekend despite a track day.
