• Audi 80 Mk II (1991-1995) - 2.0E 93L - Battery running flat 26 Jan 2008 (Forum)
  Replacing that means draining the system and getting one which costs 12 pound roughly. Luckily I had a old radiator which had one in also i put fresh coolant in and you wouldnt believe the mucjk that came out. Took an hour to replace and very simple on mine with limited mach knowledge and a haynes manual This will probably be the case for most water cooled cars, like i said it worked for me Thanks
• Ford Mondeo III (2000 - 2007) - 02 TDCI fan cycle duration. 23 Jan 2008 (Forum)
  Clearly this is not doing any major harm as it has done it for the last 100k as far as I remember and it does not lose coolant or anything. Of course I can't be sure due to road / engine noise, but I don't think it does it on the move due to the cooling effect of outside air through the radiator. Must cause quite a significant voltage drop though, as can be seen if the car is facing the garage door at night with headlights on.
• 99 Mercedes C220 CDI temperature rise 4 Aug 2007 (Forum)
  Hi, Just recently my 1999 Mercedes C220 CDi temperature gauge has started to rise higher than it has before I have checked the electric fan and that seems to be running OK but the gauge still rises above the normal centre position, It hasn't boiled over its just that its worried me when I'm in traffic as soon as the road clears the gauge goes back to normal or sometimes slightly lower than normal. The antifreeze/coolant hasn't been changed for 2.5 years would that make any difference, and has the fan got 2 speeds as while it is turning quiet fast and you can't see the fan blades it really doesn't seem be steaming it around, I have said that because on an old car I had years ago the electric fan really used to make a lot of noise when it was going and the Mercedes one doesn't Is That Normal I would appreciate any suggestion, it could just be me ??
• popping inside engine, peugeot engine 10 Apr 2007 (Forum)
  The head has just been rebuilt so is known good in all aspects, compression test shows up nothing untoward, oil pressure is spot on, coolant is dead level, fuel/air is right at idle and it only makes the noise at idle. Ive got a quick vid of it, first from the exhaust and then from the gunson so you can see it defiunatley up the engine end and you can see the brighter flashes.
• Clio 1.2 Erratic running 19 Apr 2005 (Forum)
  At idle it occasionally misses, but a couple of times it just refuses to respond to the throttle, usually coming back after a moment or two. I wondered about coolant temp sensor, but it seems to idle at about 1200 cold, dropping back to 800 or so when warm as expected, and doesn't seem to be using excessive fuel. Has the feel of an earth fault on the ECU to me, or maybe the ECU is developing a dry joint?
• Morons. 16 Feb 2005 (Forum)
  Can't recall all the figures exactly but 1 in 8 had no idea what the rear demister switch was for, about 30-40% had no idea what the air-bag failure warning light was and a similar proportion couldn't identify the coolant temperature gauge! The mind boggles.
• omega 2.0 engine 26 Nov 2004 (Forum)
  hi folks , I have been searching all day for some where i can get a 2 liter engine for my omega, i brought it a month ago and it was running great but had 1 months mot so got it cheap, i tried to mot it today and it failed on emitions, it smokes a bit at start up and idles erraticly the garage told me the engine has had it , i got it compression tested this after noon and was told 2 pots have low compression, then the guy turned around and told me he would part-ex my car for £500 against any car on his fore court which sounded dodgy to me so am not sure about what he said now, i did an oil change 2 weeks ago and the oil was ok no water or coolant. have read the conversations and am thinking about the engine centre in stratford london , has any one used them and what are they like can i trust them , i live in cambridgeshire if you know any where else better, cheers,
• 306td...no ignition?? 29 May 2004 (Forum)
  The glow plugs have been checked and are glowing as expected. There is no pressure coming back through the coolant and you can here it 'popping' through the exhaust as it is turned over. The fuel pump has not been disturbed so the pump internal timing should be fine. It is not an immobiliser problem. Its cracking me up, can anybody shed any light on other possible causes?
• Spurious VW leak 9 Oct 2003 (Forum)
  I'm wondering if any of the recnt work I've had done could have resulted in this. Could it be an AC coolant leak? I'm quite unaware of the possibilities so any advice would be greatly appreciated. Thx. S. PS My temp gauge has not been working for a while now, still waiting for VW to check it out and let me know what the problem is.
• Mazda 3 - Thermostat choices and cooling fan 3 Dec 2019 (Forum)
  Hi everyone, I've just recently got a 2006 Mazda 3 , 2.0 sport, and wondered if anyone could answer a few questions for me. The coolant temp is only running at an average of 56°c, so I know I have to change the thermostat which I plan on doing at the weekend. I can't seem to find much info on this car though despite there being so many out there.
• Any water-cooled, probably, though its complicated - Sonax Radiator Rust Preventer 23 Aug 2019 (Forum)
  Be replacing my coolant soon, since I had to do an emergency top-up with flaky water from a hose, and I will lose some more if I get the temperature sensor out for testing. Seems stuck. I could only get cheapo green stuff with Chinese writing on it last time, from RT-Mart, and I’m not very convinced, though I think I’ve got another couple of litres of it somewhere… Now they have Sonax Radiator Rust Preventer at about 4 times the price, which is supposed to be compatible with antifreeze, It makes sense to use corrosion prevention (if it works) rather than antifreeze in Taiwan.
• Ford Focus 2003 - Heater Matrix? 22 Jan 2018 (Forum)
  Also as I won't be able to get any work done for about a month at the earliest is it going to be a massive problem if I continue to drive in in the meantime? (Assuming I keep the coolant topped up and manage to actually see that is?) Thanks, any advice firstly on whether this sounds like the real problem and also the other questions. Thanks very much Ste.
• Vauxhall Corsa C - Hissing sound under the bonnet 18 Dec 2016 (Forum)
  The same thing happens when I brake and as soon as I ease off the brakes, the sound comes back. The brake fluid, coolant and oil levels are all fine so I'm suspecting it may be a burst hose? The engine check light has come on as of today and luckily enough the garage that I got it from is willing to sort it out for me.
• Nissan Qashqai - Prang - damage not immediately obvious 2 Dec 2015 (Forum)
  Tried regeneration the DPF myself but no joy, so took it to the garage. Garage have now discovered a damaged intercooler, leaking coolant (and leaking AC) afftecting the turbo, which is likely why the DPF regeneration was failing. I remembered I had a small prang about 5 weeks ago into a bollard below my bonnet line - I thought at the time it had only scuffed the plastic bodywork, but seems I caused all the damage above!
• Citroen C4 - Stop oil pressure low, just had head gasket repair 20 Jun 2015 (Forum)
  Hi I have a Citroen c4 56 plate 77k miles on the clock. I had a blown head gasket as my oil was leaking into the coolant. Had this repaired at the garage and they also changed the cam belt. 2 days later, covering only 50 miles on short distances the car started cutting out when the engine got hot and was low revs (at traffic light for example).

  Has the head gasket failed on my Golf? 15 May 2015 (Ask HJ)
  The performance of my 1998 Volkswagen Golf hasn't been great of late. I've found white gunk under the oil cap and when driving at 70mph for five mins on...

• Diesel or petrol... can't seem to decide 26 Jan 2012 (Forum)
  I have driven a Rover 220 SDi before and never had a problem with the engine components (always electrical). The coolant cap was left off for quite a while and it didn;t miss a beat. Ran on the lowest oil for I don't know how long because the oil cooler had split and was peeing it everywhere while driving. So with that experience of diesels...
• Peugeot 106 1.5 Diesel - Any ideas why this struggles to start? (video) 16 Sep 2011 (Forum)
  t=90758 The cylinder head is back on & the car is running, with no bubbles in the coolant. It's been a journey and a half, but I've learnt loads & will have a go on repairing things on the acr from now on. Thanks again ! ----- What is happening now, as it was from day one, is the car struggles to start first thing in the morning.
