[cookie7000]

hi,

i have a 2005 toledo 1.6.went on an 80 mile journey last weekend.approx half way there
the red coolant light flashed accompanied by 3 beeps,the temp gauge was just under normal.i pulled up let engine cool for approx ten minutes added approx 1/2 cup of water
to get the level exactly on the max line.set off again no probs.arrived at destination.set off again approx half way back the exact same thing happened(warning light flashed 3 beeps)
level was spot on temp just under normal.left it 10 mins started off again no probs.

would appreciate any replies thanks, cookie.

The level sensor prongs in the header tank are known to fur up and cause spurious warnings. The usual remedy is to scrape them clean with a screwdriver, though this will put a bit of crud in your coolant. Try that first?

I've had this same problem this morning, is it worth taking it to a garage or just topping it up with coolant. The only thing is as above my engine temp isn't any different to normal.

Cheers
