my girls ka has a heating problem ive put a new thermostat and housing on temp sensor and heater control valuve and its still blowing cold air throgh the dash on full speed .. only thing ive noticed is one side of the rad is hot the other side is cold have i bleed this right or have i missed some thing out please help long drive tomo ,

 

Could be an air lock? Unsure if these have a bleed nipple or not. Try running the engine, take the rad cap off and pump the hoses with your hand to try and get any air shifted.

When you turn the heater control does the cable on the heater valve move? In case the cable has snapped?

 

Near the bulk head theres a little control box with 2 pipes going into it and 2 pipes coming out. It'll be that I'm almost sure, common problem and all that.

 

yes i have changed this today Ł30 heater control vaule with a little motor on it !!

 

i get all three stages of heat control but no heat got to be a air lock but why is the rad not fully getting hot only one side where the bleed pipe is .??

 

help please



to the top

 

we have changed to switch / complete heater control panel one at work done the normal valve as you have still no heat,

I take it you lost the heat one day rather than changed the coolant then had no heat.

Are there any signs of the head gasket gone as if there is air getting into the system via the head gasket the air will got the the highest point and the heater pipes are high on ka's.

 

Take the plug off the heater control valve, stick a multimeter across the pins and get someone to turn the heater dial in the car. This will help you rule out a faulty dial, i've had this problem before.

 

had this a few weeks ago, tho the ka was overheating big time, after changing all the valve bits then the the head gasket! found out the water pump was knackered, doh
