Had my coolant level alarm starting to flash when cornering, so looks like a slight drop in the level. My alarm is a homemade contactless sensor that fixes to the outside of the expansion tank and will activate when the level drops to exactly just under the halfway seam on the tank.
I put in half a cupful to get the level back up to where I normally like it.
As a precaution I decided to check the integrity of the coolant system with my pressure test kit.
Pumped up to just over 1 bar pressure and left the system pressurised for 15 minutes. Happy to report no loss in pressure, so will put the loss of coolant down to venting of the expansion tank cap over the last 12 months or so.
The testing kit is a great item and cost me less than £30 from Ebay. Well worth the money and it will do most makes of cars.
