I have recently been searching the Internet looking for how to fix the common heater valve problem on the Ford KA. Found quite a few guides but all were just words, which is quite useless if you can’t see what it is there explaining. Specially if you’re not too clued up with car mechanics / part names etc, like I’m not. Maybe I should invest in a Ford KA Manual.


The heater valve controls the heating system of the Ford KA. If this is broken you won’t be able to get any warm air coming through from the blowers. You also wont be able to de-mist the windows front and back, not by using warm air anyway. I believe this problem can be in reverse order also. Like only hot air coming through when the cars up to temperature. I didn’t check the heating when I bought this car so was quite peed off when I got home and found out I had no hot air. With winter here it’s not something you want to be without. Not nice driving around having to wear a coat and hat, freezing your b*lls off.

New Ford KA Heater Control Valve

There is an easy fix. First go to eBay and buy a new Ford KA Heater Valve, it’s about £10 -£12. See below. Then go to this link and follow the very detailed instructions (with pictures!). A big thank you to the guy “JohnKA” for taking the time to make the guide.

Update: The owners of fk-oc.com have decided to make their pages (website) unreadable to anyone who isn’t a member of their site. This has made the link above unreachable. Unless you sign up to their website.. So for instructions on how to remove the heater valve check out these videos. Part 1Part 2. The videos are showing the heater valve on a Ford Fiesta but it also applies to the Ford KA. Everything heater valve related about the Ford Fiesta (Older models) is basically the same as a Ford KA car of the same years.  The maker of those videos (TK42138) also has videos related to fitting the new Heater Valve. See one of those here.

I fixed mine today, some of it was quite fiddly but I got there in the end. What made it hard for me was lack of tools for the job. I only had a small pair of pliers so getting those hose clips on and off was tough. Make sure you have a nice pair of mole grips like the ones “JohnKA” is using. Makes the job a lot easier.

    Hi, thanks for your comment. I have to say, Ive had many different cars big and small, and I hate to say it just incase something now goes wrong with it, but the Ford KA has been the best of them all in terms of reliability. The engines just seem to go on and on. Engine is tappety but that's the way older KA engines are after a while. Mines a 1999. Rust is an issue. Mostly round the petrol cap, wheel arches, and at the bottoms of the doors. For my last MOT the car needed some welding done but other then that it's been trouble free. Heater control valves play up to but are a cheap DIY fix.

    In terms of run arounds you could do a lot worse then a Ford KA.

    Also I forgot to mention. Petrol is OK but it's not as good as I was expecting to be. It's not a 1 litre it's a 1.3 so it's decent but not incredibly fuel efficient..Specially with the price of petrol now.

    But all in all highly recommended. Goodluck.
