coza Posted June 13, 2012 Share Posted June 13, 2012 Hi, Not good Im looking to sell my car next month, I've noticed the heater works randomly meaning some times when I put it to hot air it's like luke warm some times it's hot but If I want cold air it's cold all the time, I noticed the top water hose is rock solid ?? Any idea what's going on ? Cheers Link to comment Share on other sites More sharing options...
Iky Posted June 14, 2012 Share Posted June 14, 2012 Might have airlock. I mean a bubble of ait trapped inside. Also knackered rad caps can cause problem. Link to comment Share on other sites More sharing options...

Might as well fit another thermostat as well. They only cost a few quid. Link to comment Share on other sites More sharing options...
