• 1.4 TFSI - Audi Q2 Coolant Loss 13 Oct 2022 (Forum)
  I had the cambelt changed on my Q2 1.4 TFSI {25000 miles} at JCT600 after the work was completed i drove away and lost all my coolant over a distance of 10+ miles. The dealer has checked the car and is saying a thermostat hose has split but because this is on the the opposite side of the engine they cannot take the blame. My car was running perfectly prior to having this work done and i have never topped up the coolant in the 3 years owing the car.
• Volkswagen touran 1.6 TDi - Black coolant Bad fumes 18 Sep 2017 (Forum)
  I began smelling a strong acrid smell in the car, enough to burn my eyes and back of throat. I returned it to the VW garage and they agree about the fumes, and they also found the coolant to be black with what appears to be soot. They do not know the cause, although they seem to know it is unrelated to their previous work. They have sent the coolant fluid away for analysis. I cannot help feel it is related to their emissions update and EGR work.

• MINI MINI Cooper and S R56 (2007 - ) - 06 1.6 Another one loosing coolant 3 May 2010 (Forum)
  Just before Christmas i was driving the wifes mini when the heater suddenly started blowing cold air and the temp gauge started moving around erraticaly. upon investigation it appeared that the coolant level was low, took about a litre to top up. All has been fine but now the level has dropped again . No Mayo in the oil but coolant does look discolored. Is this looking like a head gasket failure?
• Volkswagen Golf III (1992 - 1997) - 97 2.8 Flushing / cleaning coolant system 14 Jan 2010 (Forum)
  Since I bought my car about 6 years ago, the coolant has been a sort of brown colour, instead of pink. I've changed coolant lots of times, flushed it a number of times with water / flush until it all runs clear, but the brown colour always comes back.
• Nissan Primera III (1999 - 2002) - 00 1.8 Antifreeze/coolant query 26 Nov 2008 (Forum)
  I had heard of a 'universal' coolant called Bluecol U which is supposed to be okay for topping up anything, but I can't find any stockists with it in my area or even close. Anybody any suggestions over what I might be able to use to safely top up?
• Peugeot 306 (1993 - 2001) - 2000 2.0 HDi - Coolant loss 13 Aug 2008 (Forum)
  SWMBO's X -reg estate (sixty-odd thousand miles) has recently started to need its coolant level topping up - about half a cupful every fortnight, low mileage covered in that time. An inspection under the bonnet and under the car reveals nothing. (Mind you, the car stands on gravel.) All the hoses I can see and/or touch seem dry, with no trace of residue.
• Astra 1.4 coolant leak 28 Sep 2005 (Forum)
  A 15/20 mile drive will result in about 1 pint loss of coolant, having to top up everyday. no visable evidence of leaking, checks have been made for heater matrix, radiator and pipes. Head Gasket has been metioned, but I am trying to see if it can be anything else before embarking on an expensive trip to the garage.
• Cooling system - lost coolant. Megane. 29 Jan 2005 (Forum)
  I was noticed slight smoke coming from the engine after a long journey. When I took a look, the coolant tank was completely empty, (was checked a few weeks ago and was okay). My questions are... I've obviously lost the coolant "somewhere" - any suggestions where to look. The pipes look okay - the radiator is a sealed unit so I'm not sure how to check this is okay.

• 1.2 TSI - Seat Toledo TSi coolant leak....water pump 9 Aug 2021 (Forum)
  Had cambelt changed recently  but not water pump as it is on the other side of engine and is belt driven.  Noticed coolant level down, warning light, and found leak was from under the plastic housing.  Turns out this is a well known issue and a back order at SEAT for the parts.  £180 for water pump and housing £60 labour by a former SEAT mechanic.
• Honda CRV 2.0 2003 - Honda Type 2 coolant and changing fluids 20 Jun 2016 (Forum)
  Just looking into getting hold of the materials to do a 'fluids' service on my new CRV, and cannot believe the amount of discussion online about using OEM Honda coolant.  Is it really that critical? I've acquired a Honda service manual and the other fluids (PAS, gearbox, diff) seem straightforward enough to change, but while I'm writing this I might as well ask if there's anything to watch out for.
