• Volkswagen Sharan (1995 - 2009) - 1998 1.8T 'mayonaise' in Header Tank 7 Dec 2012 (Forum)
  A friend has just brought a V reg 1.8T Sharan with 90k on the clock. I was checking it over for him and noticed that there was a thick layer of "mayonnaise" on top of the coolant in the expansion tank. However there was no sign of any under the oil filler cap, and the oil has not been changed

  Hi, I recently had a water pump and thermostat housing failure on my 2006 1.25 Fiesta Style. The RAC towed me to a garage, who replaced the failed parts, plus the auxiliary belt as it was coated with coolant. I've since taken my Fiesta to another garage (who I believe

• Ford Focus - Ford Focus 03 Ghia 1.8 TDCi - climate control dead 19 Nov 2010 (Forum)
  ) but the heater, blower and air con are all dead. No output at all, although the engine speed reaction is still there when the air con is turned on or off. The screen heaters still work, and the coolant is getting up to temp as normal. Resistors? Fuses? Switches? Anything particularly common that fails
• Clio Starting Problem 7 Nov 2010 (Forum)
  it does it runs fine. Sometims though it starts first time. I've searched the forum and someone had a similar problem when the engine was hot and fixed it by replacing the Coolant Temperature Sensor but my problem seems to occur mostly when the engine is cold. Could it still be the sensor that needs

  ) we had a look at the engine, oil is fine, coolant etc all ok. but the engine is shaking like mad! The noise when it's revved rattles even more. It's going to be booked in tomorrow but wanted the heads up from you guys first. It's very difficult to explain but maybe i could emphasize

  I have had problems with my Rover for the past couple of weeks with an overheating engine... I have had the thermostat replaced, which seems to have worked by bringing the temperature gauge down....BUT.... The water in my coolant tank is boiling over if the engine is left running for a little

  of fumes and no power to get going properly. (Once the engine warms up, there's no problem at all and the car runs beautifully). I had the coolant temp sensor replaced a year ago which seemed to improve things slightly, but now the problem is back with a vengeance. Any ideas or suggestions would be much
• Volkswagen Golf III (1992 - 1997) - 97 2.0 GTI - Engine component locations 15 Oct 2009 (Forum)
  sort. What is it measuring Oil temp? Another Coolant temp Sensor? 3) On the intake manifold there is another one wire sensor on the right hand side (opposide end to where the hose goes to the air box) (again from the front) what does that measure? (Air temp / volume is in the air box) Many thanks
• Rover 25 (1999 - 2005) - 02 1.4 Losing a fair bit of water! 14 Oct 2009 (Forum)

  Less than 4 yr old, 53,000 mile on the clock, recently got error message "insufficient coolant". VW garage (which has always maintained it) advised oil cooler and camshaft needs replacing, £2,500 bill! Considering age & miles, does this seem strange to anyone else? I know very little about cars

  cuts out. You can try to start it may be 3 or 4 times before it will idle over OK. There are no fault codes on the ECU, I've already changed the crank shaft positioning sensor, the air inlet temperature sensor & the engine coolant temperature sensor, but none of these has made any difference. Does

  I have a petrol AEX engine which has a lot of "mayo" in the oil filler cap and has always (during the several months we've had it) run with a "tappet" type noise from the head. It seems to use too much oil and coolant and I expect there is a small leak internally across the cylinder head gasket

  dies. You can repeat this up to 3 or 4 times before the engine will idle successfully. If you can catch it on the accelerator you can keep it revving and then it's OK. I've changed the crankshaft positioning sensor & the air inlet temperature sensor. I was going to change the engine coolant

  or 4. When off or on 1 or 2 it doesnt seem to be happening. The first thing I thought of was heater matrix and this is only because my brother had similar problems with a Nissan Primera. I checked the coolant bottle under the bonnet and is full. Any ideas? Could it be something related to: http
