  Why can I hear water flowing through my Vauxhall Astra's heater matrix? 20 Jul 2010 (Ask HJ)

• Peugeot 307 - Peugeot 307 head gasket 29 Mar 2010 (Forum)
  My mum asked me to have a look at her car, as it keeps beeping and flashing a message about topping up coolant. Anyway, to cut a long story short, the coolant system is getting very pressurised, and pushing water out of the expansion bottle, setting off the sensor. Remove the top and water rushes back in (pressure is there even when it's been left for a couple of days!).
• Peugeot 205 (1983 - 1997) - 86 1905 Puzzling Mi16 cold idle problem HELP! 6 Oct 2009 (Forum)
  The problem seems to be the switching of the idle control valve. For some reason it isn't getting the right signal to turn on or off. Coolant sensor was changed and this did not affect anything apart from increase the fuel consumption so I've put the old one back in. Coolant sensor is getting 5V at the pins. Could it be this or maybe the tps, I'm not sure how to check this so if anyone has some advise on voltages or resistances I should be checking please contact me.
• Rover 214 - head gasket failed?? 25 Jun 2007 (Forum)
  Hi all! We have a P-reg Rover 214 (P) whose coolant tank has mysteriously run dry - no signs of any leaks and only topped up with water 2 weeks ago.........then whilst being driven last week emitted a nasty strong odour and started 'bubbling' under the bonnet.
• Punto cooling/running problem 30 Nov 2006 (Forum)
  I have a problem with our Punto 60S 1240cc 8 valve. 1998. It started on 3 cylinders one day last week and was blowing bubbles into its coolant. I tried a can of ?K Seal?, but no use, so off came the head. No 1 had a tiny groove in the head, only about 20thou wide & deep, but it bypassed the thick section of the head gasket. The local breaker supplied a replacement head complete with manifolds, sensors, ignition packs & camshaft.
• service idea 10 Dec 2005 (Forum)
  hi looking into starting my own servicing company and wondered wat you all thought of the idea, basically 3 service levels, 6 month, annual and 3 year and they go as follows 6 month, approx cost £40 plus any extra parts oil/filter change levels check tyres/pressures check coolant level check brake/discs check rad fan check spark plug/glow plug check annual service, approx cost £70 as 6 month service plus brake pads/shoes changed air filter changed fuel filter changed compression test valve clearences checked exhaust checked electrics/mot test items checked spark plugs/glow plugs changed 3 year service, approx cost £250-300 as annual service plus brake discs changed coolant change cambelt/tensioners changed fanbelt changed headgasket, head decoked waterpump changed gearbox oil changed bushes/rubbers mechanical components checked can anyone spot anything glaringly obvious i missed or have an opinion on the idea are the costs right or to expensive obviously things will differ car to car and the timings for services aren't fixed but ive always ran my cars by the above and they've been great and haven't ever suffered a major mechanical failure cheers chris
• Toyota servicing - is this reasonable? 20 Jun 2003 (Forum)
  Just had a quote for a 3 year / 30k mile service on the Yaris which has rather stunned me. They want £118.50 for the service and another £50 to change the coolant which is due at the 3 year mark. According to the book, a 3 year service in an intermediate comprising oil and filter change with brake, tyre and light inspections. Also, as it's 30k there is an air filter change.

• Stellantis - Main dealer rip-off 19 Jan 2024 (Forum)
  A colleague had pointed out to them their car was leaving pools of liquid under it when parked. They admitted they were having to top-up the coolant regularly, so they tried to book it into the main dealer, who stated there'd be a £180 charge to plug it into diagnostics! They took it to a local quick-fit type place, who looked under the bonnet, told them it was the water pump and gave them a price to replace it.
• BMW 3 Series 318d - 318d 2010 replacement water pump, engine damage? 15 Sep 2019 (Forum)
  The mechanic says i should get rid of the car, the engine is running fine but as i ran it on low coolant for a few days, he thinks the engine might be troublesome down the line, though no overheating light came on.  Any opinions on whether he could be right? Thanks
• Vauxhall corsa comfort 1.4 automatic - car not starting when hot 2 Oct 2016 (Forum)
  When my car is cold it starts no problem, but when I turn the car off and try to restart it when it's hot it will not start, there are no codes found, Eml not coming on. Changed crankshaft sensor, camshaft sensor, knock sensor, lambda sensor, engine coolant sensor, fuel pump relay, spark plugs, you name it. Can anyone think of anything else?

• Ford Focus 1.6 TDCi - MOT Diesel Emissions 10 Jun 2014 (Forum)
  MOT due next week and I think the coolant thermostat has failed. The car has always taken a long time to warm up but now it only gets half way up the guage unless it sits in traffic just ticking over when it goes up to "normal" at the top of the guage.

• Volkswagen Golf IV tdi - temp gauge 25 Jan 2012 (Forum)
   Sometimes it seems to be rising and then goes back down again. Is it just a sensor or is the coolant just not getting hot enough. The heating system seems to work fine so I guess it must be electrical, Any suggestions anyone?
• Volvo V40 11.9 tdi - Dodgy temp gauge 7 Apr 2011 (Forum)
  Also - when he stops, the engine fans continue running at full speed and make a lot of noise. They continue for about 5 minutes after switching off. Car has plenty of coolant and is not overheating, could this just be a dodgy thermostat or sensor?
