  ).  At first I was getting mid to low 30's mpg.  The engine wasn't running at normal temp (true reading from the cliamtic control panel showed the temp wasn't going above mid 60's).  I've since replaced the coolant temp sender/thermostat and coolant (50/50mix) and the car now runs at the normal

• Ford Focus TDdi - Engine cooling fan 19 Jul 2010 (Forum)
  Hi all I have an 02reg Focus 1.8TDdi diesel with 160k on the clock, which so far has given me 10k of trouble free motoring since I bought it just before last Christmas. However, I have recently noticed that the coolant fan seems to come on every time I accellerate to above 50mph
• Rover 214 - excessive exhaust emissions 26 May 2010 (Forum)
  a week we noticed white smoke - thought gonna be the head gasket - bought the kit and fit everything as it should be just in case it should blow.  Spark plugs were dry and clean.  The gasket had slight evidence of a possible blow but no mixing of oil and water/coolant evident - the head
• Ford Focus (1998 - 2004) - 99 1.6 cooling fan too keen 29 Jan 2010 (Forum)
  the coolant. There seemed to be an airlock as the temp gauge went high and erratic, also the coolant level dropped. Topped up and it hasn't dropped since. But soon after that the a/c would not switch off. New switch fixed that but temp gauge was still erratic. New temp sensor in the head failed to give
• Ford Focus (1998 - 2004) - 99 1.8 Burning Smell coming through vents 30 Mar 2009 (Forum)
  lights. And I think the smell comes from acceleration. Although after a long journey along country roads and some pretty big hills the smell was particularly bad. I've had a look under the bonnet and noticed what looks like coolant residue (flaky pink stuff) on the right hand side of the engine. I've
• FIAT Grande Punto (2006 - 2009) - 2007 1.9 Poor Fuel Economy After Crash 28 Nov 2008 (Forum)
  etc. Any how I have now noticed that my average fuel consumption has gone from being about 42mpg down to 35mpg after the crash. The only thing I can think is that when the accident happened all the coolant from the engine leaked out of the pipe that connects to the intercooler. I have noticed
• 2000 w plate Pug 1.9D oil/water leak 2 Mar 2007 (Forum)
  pug contacts and they confirmed this as a possibility. Get on with the job then sir and £80 later job done. It still appears to be leaking coolant, which is now grey rather than black although i would expect this as although the system was well flushed out the radiator has not been changed. My
• focus hell 1 May 2003 (Forum)
  coolant water in and around the spark plugs and also inside the engine - fifteen minutes of blowing steam was testament to this! The garage repaired the car and clamed the fault was due to a "temperature reader/sender" fault which was then replaced.I enquired whether it might instead have been a cylinder

  I was driving my 2002 1.5 Renault Clio diesel (78,000 miles) the other day when the engine started to make a gurgling noise. I pulled over straightaway,...
• Extralube ZX1 4 Mar 2015 (Forum)
  Has anyone used this water/petrol/coolant additive in the past. I have and believe it has had a positive effect. Anyone else care to comment? I was thinking of buying some more but it's quite expensive. Can anyone suggest where I might find some reliable test-data? before I shell out again
• VW Golf GT TDi 115 PD 2001 - Overheating 29 Oct 2011 (Forum)
  Hope someone can help, have recentley bought this car, superb history, had new rad, water pump in January. Just had new coolant sensor and expansion tank put in, but still overheating. Fine for small journeys, but motorway nightmare
• Hotter heater radiator additive 28 Oct 2006 (Forum)
  I saw an advert in a motor mag about a product that claimed to help the internal heater heat 50% faster. The product is called something like Hotter Heater or similar, just add to the radiator coolant and away it goes. Has anyone used this product and if so how effective is it and is it safe
• Humph 12 Jul 2006 (Forum)
  Why ask someone (me) to go and look at a car with you, if you ignore what I say? £650 for a 3 door N reg Fiesta 1.25 with 98,000 on the clock, but with no oil in the sump or road tax and a rapidly decaying battery. Think it had the wrong coolant in it too. Still, I got twenty quid out
• Frontera heater matrix 5 Aug 2003 (Forum)
  I have a j-reg Frontera 2.3 td that has developed a leak in the heater matrix, (passenger footwell constantly soaked and coolant disappearing!). Is the heater matrix the same as any other vehicle (so I can get one from the local scrap yard, I'm a poor man!), or is it specific to the Frontera
• Volkswagen Polo III (1994 - 1999) - 1996 1.4 - gunge around oil cap 28 Feb 2008 (Forum)
  Hello, I've performed my fortnightly oil and water check today and noticed my coolant was right down - not enough to set off a warning light but it must've been blooming close to it. Anyway, when I opened up the oil cap I noticed a fair build up of creamy gunge clinging to the bottom of the cap
• vw corrado/golf gti eng. temp. problem 22 Dec 2004 (Forum)
  a replacement gauge but I had to figure out what was causing the problem before fitting the replacement one. I also have some coolant loss but despite many checks there is no evidence of coolant loss anywhere in the engine bay. A couple of friends and some Tech. Motor club members suspected the Engine Coolant
• 306XLD heater,idling,coolant,humming 8 Dec 2004 (Forum)
  it hovers around 750-800RPM but when warm is around 1000-1100RPM! Any ideas? Do I need to replace the Fuel Filter? I have serviced my old petrol engines but not diesels. Is there something I need to reset? 3. The coolant needs topping up every 2 weeks. I'm guessing it's a pipe leak, but someone said
• Mercedes Aclass - New thermostat 29 Aug 2024 (Forum)
  Just trying to make sure I’m not being ripped off, but my coolant is leaking and Mercedes main dealer have phoned to say the thermostat needs replacing (unusual for a car only having done 45k miles they said) anyway the quote for a replacement including VAT and Labour is £700. Does this sound right
