• Cooling system flushing 4 Dec 2004 (Forum)
  Could anyone please clarify why it's necessary to remove the themostat when flushing engine coolant passages? Does the presence of thermostat (closed) trap coolant in a particular part of the system? I recently drained my Passat's coolant (without removing the thermostat) and although I didn't
• Water for Coolant 5 Jan 2004 (Forum)
  Happy New Year all. We all know that deionised water is best for use in the coolant mixture of our engines. However, how about using water collected from a dehumidifier? Presumably this water is at least soft (it won't contain any of those hard salts like tap water) and so should be suitable
• Ford Fiesta - Coolant leak 1 Aug 2022 (Forum)
  Hey all  I have a 2009 Ford fiesta (1.25) and a big fat coolant leak. I topped it up (actually above the max line) and the coolant dropped below the minimum line after about 70 miles of driving.  I'm just wondering the best way to go about fixing it. I'm unemployed right
• Volkswagen Golf - 51 VW Golf - Engine Coolant 11 Feb 2019 (Forum)
  Hi all,  I've had the engine coolant light come on my Golf; quite unexpected but on checking the reservoir it's certainly low (below min). Obviously this suggests that there's a leak somewhere in the system and that I need to get it to a garage, but just two quick questions
• Ford Focus (1998 - 2004) - 99 1.8 advice please about replacing coolant 30 Jan 2009 (Forum)
  I have the dilemma of needing to change the coolant on my Ford Focus (Petrol). The car still has the original water pump but the timing belt has already been changed 18 months ago so I am very reluctant to change the water pump at this point unless it was actually leaking because of the cost
• Peugeot 306 (1993 - 2001) - 1996 diesel - Coolant in passenger footwell 19 Nov 2007 (Forum)
  Found a puddle in the passenger footwell of my 306 today, and thought I had a leaky door. After soaking it up, realised it smelt of coolant, and sure enough, opened the reservoir and I've lost several pints. Thinking back to yesterday, I did turn the heater on for a few minutes, and it smelt
• Rectification of coolant leakage 25 Feb 2005 (Forum)
  How bad does a coolant leakage have to be before it warrants rectification? The leakage on my car is not sufficient for me to notice a drop in the level in the header tank in the 4 months that I have had the car, but there is definitely an ongoing leak. I've cleaned away the pink antifreeze
• How long does coolant last? 6 Jul 2003 (Forum)
  I've just been reading "Car Mechanics" letters pages. A woman whose Toyota seized up after 11 years was complaining. The water pump had gone, which took the cambelt, which wrecked the engine, which made the car economically unviable. In her service book, it said that the red coolant was filled

• Ford Focus - Foamy Dark Yellow Coolant 19 May 2010 (Forum)
  Hi All, Had a look under the bonnet of my other half's 2001/Y MK1 TDDi Focus to see that coolant had been spraying out from the pressure cap. The coolant is foamy and a dark yellow colour, and has stayed that way once cooled down. There's a layer of foam with coolant liquid underneath

• VW vr6 engine - Knock sensor leaking coolant? 21 Dec 2020 (Forum)
  Struggling to find a coolant leak. It's a slow drip, when engine running it's faster.  Looks like it may be coming from the knock sensor. Anyone else had this? Do I have to replace the sensor?
