  Used Van Buying Guide: Volkswagen Caddy 2010-2015 16 Jun 2025 (News)
  Ask if the water pump has been replaced recently, they’re prone to failing. If it’s using a lot of coolant on longer runs it’s on its way out. DSG automatic transmissions don’t have the best reputation for reliability, check it’s been serviced properly, as a replacement can cost as much as £6000.

  I'm really concerned and embarrassed with my 2012 Alfa Romeo Mito 1.3 JTDM producing clouds of white smoke during DPF regen. After removing the DPF and...
• Toyota Auris - Car Struggling To Start 30 Mar 2025 (Forum)
    When the car does start sometimes I hear a bubbling noise whilst driving (possibly from the radiator) and the coolant has needed topping up several times in quick succession which is weird. The last week the low oil light came on and I topped it up. It's come on again today and it's a little low but no milkyness on the dipstick.

• 1.4 cvh 55kw 1998 - Ford escort overcooling 12 Jan 2025 (Forum)
  I have read about the cvh thermostat housing and it has some kind of plastic ball inside that melts when engine overheats which i think is my problem because last year my engine overheated because of faulty fan when it overheated i replaced the coolant tempeature sensor and the thermostat thinking it would help but it didnt since then i have no heat :( . Now that i know the ball inside is melted i know that coolant is bypassing the thermostat going straight into the radiator.
• Peugeot 308 - Cooling fan cuts in/out constantly 29 Dec 2024 (Forum)
  I have to do this approximately 1 in 5 times I switch off the car.  My first thought was the coolant temperature sensor, however the temperature gauge seems to be accurate and rises as you would expect. I was wondering if anyone has any ideas or experiences of this before I start throwing parts at it!
• Millers Oil analysis of oil sample 27 Nov 2024 (Forum)
  Wheeler Dealers bought a Jaguar S type V8 with 200k miles and sent an oil sample off to Millers to find if the engine was in good shape. High levels of sulphur was detected which indicated coolant loss, possibly down to head gasket failure. Seems a sensible option before rather than after buying a car ?

• Volkswagen Golf Mk6 1.6 TDI - Please help -- VW Golf overheating 6 Nov 2024 (Forum)
  When I carry on driving the needle slowly returns to the 90 degree position and then stays there until the next time it happens. In addition, I've been losing coolant and having to top up. But the temperature rise still happens even after I've just topped up to the max mark. As you will have gathered, my technical knowledge is severely limited. So any advice you can offer would be much appreciated.
• Ford Fiesta - 2005 fiesta overheating - temp gauge normal 26 Oct 2024 (Forum)
  The thing is the tempature gauge shows normal when the coolant tank is bubbling up and steam coming from it. Shouldn't the tempature gauge show that the engine is overheating if it was this fuse? So I'm wondering if I'm going down the right lines with looking at the fuses?
• Suzuki Vitara - Should have followed my own advice 17 Sep 2024 (Forum)
  It meant kicking our heels for four hours. And that was “While you wait” service. They reported coolant leak stains but said it might be historic as levels were OK. They suggested I monitor it for 250 miles. Next day I checked the coolant level after 50 miles. It was low, just over the mark. I smelt a rat re the level having been properly checked at the service.
• 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.
• Vauxhall Corsa 2012 - Radiator fan doesn't turn on 16 Aug 2024 (Forum)
  Hello, I've had a problem with a blown out coolant hose and now that I've replaced it the radiator fan doesn't turn on. Yesterday the radiator fan turned on as soon as I turned the car on. The coolant temp today was at 108 highest and no fan turned on.
• Renault Clio 2 1.2 16V - Overheating 14 Aug 2024 (Forum)
  Younger daughter today on a road trip rings me to say a couple of warning lights are on - further questioning reveals the temp gauge is well above mid-point. It would then cycle up and down a few times then stabilise. I’ve had to add coolant - expansion tank being empty or close on empty, I can’t see an obvious leak in the few minutes I’ve had, but I do know that the engine fan is cutting in. I’ve ordered a new thermostat, and will hunt for a leak around the housing, but anyone any other likely suggestions.
• Ford Fusion - Coolant leak 11 Jul 2024 (Forum)
  Our trusty old Ford Fusion (2003 - 1.6 petrol engine) has been leaking coolant for a couple of years now, and we simply top it up every week or two with about 100 ml of coolant. The coolant drips from the bottom of the engine sump, but seems to be coming from higher up somewhere behind the AC compressor.
• Chevrolet Matiz 1.0 SE Plus - Foam in coolant expansion tank, but no white smoke 7 Jul 2024 (Forum)
  I've just bought a 2009 995cc Matiz. Driving home the coolant light came on. I topped up the coolant (it was low) and ran the engine for a few minutes with the cap off and foam appeared in the expansion tank. The expansion tank or foam doesn't look oily and I checked the oil cap and dipstick before buying and saw no mayonnaise.

• Vauxhall Insignia - Is it likely I've been scammed? Head gasket went? 2 Jun 2024 (Forum)
  During selling my old car, one buyer called me to the boot while the other was at the bonnet. When I went to the front, he had just finished doing up the coolant cap. He then asked to take it for a spin. Thrashed it then opened the bonnet. Proclaimed the gasket had just gone. The coolant tank was thick with black oil and trickling over. I took pictures of it.
