• Mercedes-Benz C-Class W203 (2006) - Engine Services Light on and staying on 2 Apr 2012 (Forum)
  Driving home tonight, the engine services light came on. I drove about half a mile home then checked the oil and coolant. Coolant = OK Oil = Low, I put about 2 litres in (no sign of leaks but not long had dealer service) I had no indication that the oil was low from engine services which I should have got.
• Ford Fiesta (1995 - 1999) - 97 1.3 cold heaters even with hot coolant 5 Nov 2009 (Forum)
  So my question is - is there an airlock in the rad or has the water pump given up? I mentioned the pump because when the engine is revved the coolant in the header tank doesn't move, whereas on previous cars ive had, the level will drop with the revs as I understand it is supposed to. Thanks in advance for any help!

• CLA 180 - Engine management light 3 Aug 2018 (Forum)
  I was driving on a nice sunny day with the air condition on and suddenly the engine management light came on. I carried out a diagnostics and error code P0128 came up. It reads: Coolant Thermostat {Coolant Temperature Below Thermostat Regulating Temperature). I cleared the error codes and it was fine for a few days until I decided to drive with the air condition again. Please does anyone know what is going on here?

• Jeep Cherokee - Heater Matrix 12 Jan 2011 (Forum)
  I've found pudles of engine coolant in the footwells and in all of the air vents. I'm assuming that the heater matrix has either sprung a leak or become disconnected. The manual has a lovely sketch, but it isn't clear where it's actualy located. the car is right hand drive.

• Ford Mondeo Mk3 - Tdci - Strange overheating problem, only at speed 4 Jun 2018 (Forum)

• VW Polo 1.2 2004 - Tricky coolant leak 6 Nov 2017 (Forum)
  Hi all. My polo has been losing coolant for around 2 years now and I’m struggling to find the source of the leak. It needs topping up around once a week (I drive for around 30 minutes each day). There is no visible leak from the car when cold or hot, and the entire system has been pressured tested when hot and cold by both the AA and an independent garage.

  So is this heat gain from the engine doing a lot more work, as it obviously is, or is it from the transmission heat affecting the engine temperature via the coolant ?  
• Citroen Saxo - Head gasket 24 Sep 2012 (Forum)
   This was the first time the coolant light had come on and there had been no other indications that the engine was over heating. Several questions: a) Would the head gasket not have been changed when the cambelt was? b) If so, is it normal to only last 18 months?
• Ford Focus 2004 - Temp gauge issue !!! 8 Mar 2012 (Forum)

• Toyota Carina E (1992 - 1997) - 95 1.6 Expansion tank tube missing? 16 Feb 2010 (Forum)
  Bought a nice low mileage Carina off of a friends dad, and I have a question about the coolant expansion tank. The coolant level in this was just over full, however when I unscrewed the actual radiator cap I noticed that the coolant level in the radiator was well below the fins, so I topped this up.
• Peugeot 106 (1991 - 2002) - 2000 1.5 Coolant Temperature light - on or off? 5 Apr 2009 (Forum)
  .********* Trouble is I have now noticed the coolant temperature warning light on the dash board does not light up when the ignition in turned on. I'm pretty sure it was coming on before but I can't be certain. I have an older 1995 106 XND and the light does come on with the ignition and goes off when the engine starts.
