Why bother fixing a 03 Ka ? Simply because it's 60k miles 1 owner who I know well and was never used in winter because they're in the USA for 6 months. So I bought it for my D. i .Law and after a year of good use it overheated and lost water. I made a start on stripping stuff off to get @ the plugs and do a comp. test. Found the thermostat stuck - replaced it and tried again - overheated and didn't appear to be circulating. So I put a new water pump in ( had previously tried all sorts bleeding air out ) The old pump squeaked when turned but hadn't broken as such. Now it's filled up OK - air bled itself out and it appears OK. I can't figure it out though, but I know it's a horrible little thing to work on. What do you guys think about the overheating, it's now fine!
