Car.Ford ka

im having a few problems what i really cant diagnose :L
the main one being that im loosing coolant, not drastically fast but filling up every 2 days,
the engine feels a little to hot sometimes, and after i topped up the collent the other cay the car sounds like its slurping when its cooling down, ive changed the coolant bottle&cap, and the thermostat, and ideas?

Possibly the head gasket. Does the underside of the oil cap look like it's covered in manky mayonnaise?

[fordforever]

no, i havent seen any signs of a head gasket yer :L

HG failure doesn't always mean oil will contaminate the water - look for soot deposits in the expansion tank and do a pressurisation test -

Things to also check are the expansion tank cap and for any cracks or breaches in the system
