• mayo in coolant reservior MKII golf 16 Jul 2003 (Forum)
  My dad got my grandad's golf (he had owned it since new), hasnt done much (29000), ive got it now that ive passed my test (done around 500 miles mostly in the last month). I thought i better check oil and water and found mayo under the coolant reservior cap, on closer inspection there seems to be quite a lot of it in the coolant tank, but still a reasonable level of coolant fluid in the tank (blue coloured) since when u squeeze the radiator pipe the blue liquid squirts to the surface.
• 10 year old corsa issue 20 Aug 2023 (Forum)
  Did a 400 mile journey yesterday and pulled over for a break. When engine restarted power steering wasnt working and can't get above 2000rpm. Coolant was spilling from the middle of the car and none showing in coolant reservoir. Ended up getting towed home. I have readded some coolant but clearly an issue.  Power steering seems to be working but still cannot get above 2000 rpm.
• 406 coolant problem - head gasket leak? 19 Jun 2012 (Forum)
  Did a simple recommended test - engine running, expansion tank cap off, can see small bubbles in the coolant expansion tank. Garage has performed a pressure test and has said "makings of cylinder head gasket leak". Cost to fix £400-£500. Are they correct or could it be just a unseen leaking pipe, leaky temperature sensor, etc?
• Citroen C5 Hdi (2001) - Coolant loss without leaks nor head gasket probs 16 Jun 2012 (Forum)
  Hi, Any thoughts appreciated...!  My C5 is losing a lot of coolant and needs topping up every couple of days.  I've had the head gasket checked and there's no problem, there are no leaks and I've changed the cap to the resevoir so it's not escaping there.  The engine starts fine and the car is driving fine.

• Toyota Camry 2.4 vvti petrol - Loosing coolant 29 Dec 2010 (Forum)
  Hello I have a problem with my Toyota Camry 2.4 vehicle. It is a 2002 model. At present, I am loosing coolant at a rate of about 1/2 per 2 days or so. Can someone suggest what initial tests I can perform to find out what the cause might be; I fear it could be a head gasket, but please let me know what equipment I should use.
• Peugeot 106 (1991 - 2002) - 96 1.5 Has the head gasket gone 10 May 2009 (Forum)
  Hi Everyone, My Dad has a 106 1.5D which is losing coolant. It has only lost 1/4L of coolant over ~2000 miles / 3 months so doesn't seem to be too bad - yet. It seems to be coming out of either the head gasket or the vaccum pump(?) at the thermostat housing end.
• Ford Mondeo III (2000 - 2007) - 2001 1.8 Overheating 14 Mar 2009 (Forum)
  Noticed my mondeo keeps on overheating. There's gunk in the coolant expansion tank. I tried draining the radiator and, assuming I found the right drain plug(!), not a lot came out even though I've now topped up the coolant. What did come out looked suspiciously like screenwash (bright yellow).
• Audi A6 + RS6 (1997 - 2004) - 1999 1.8t Low coolant temperature at high speed 30 Sep 2008 (Forum)
  Fitted with standard viscous-coupled fan and electric fan. All completely normal at town speeds. At high speed, the coolant temp falls to the bottom of the guage. After a bit of experimentation this turns out to be engine speed related. Anything above 3800rpm for any length of time and the temp falls rapidly. Reduce engine speed for a few minutes and all returns to normal.
• Citroen C5 (2001 - 2008) - 02 2.0 HDi 110 Loss of coolant. 24 Apr 2008 (Forum)
  My 2002 Citroen C5 Diesel 2.0 HDI 110 has suddenly starting losing coolant, about a pint every 100 miles or so. There are no visible signs either of a radiator or hose/connection leak, or of stains on the ground. The car has done 68,000 miles. I asked my local garage (not a Citroen dealer) to have a look whilst it was being MOTed and he could not find anything- it behaved normally under an overnight pressure test.
• Audi A4 Coolant Hose 16 Jun 2007 (Forum)
  Does anyone know where I can locate an Coolant Hose for an Audi A4 2.0 SE Petrol. The main dealer says a back log of 10 days is on. Ive been without my car for like 6 days already, Ive tried local salvages and VW and Skoda, which are both the same as Audi.
• Morris 1800, Volvo 740 coolant loss 15 Mar 2004 (Forum)
  Many years ago when a teen-ager, I can remember that my dad's Morris 1800 "land-crab" suffered from a problem when you finished driving and the engine was hot, when the engine was turned off the coolant overflowed in copious quantities and had to be topped up before the next journey could be started. I cannot remember what the fix was - this is going back to about 1974. I've now come across an aquaintance who has the same problem with a Volvo 740 (petrol engined too).
• Ford Fusion - Engine overheating 21 Feb 2024 (Forum)
  Please can anyone suggest my best way forwards. My engine seems to be overheating as the coolant boils out of expansion tank and makes a mess. I tried a test this morning with a cold engine and coolant refilled to the maximum mark: 1) Started cold engine - still no leaks from anywhere after 15 minutes 2) Attached OBD reader to see temperature with engine running 3) Waited for temperature to rise and cooling fan to kick in 4) Thermostat appears to open okay as hose to radiator becomes hot 5) Temperature got to 101, still no fan, coolant starting to rise in the expansion tank 6) Decided to switch off engine - did so - fan suddenly kicked for just a few seconds 7) Restarted engine - temperature 99 - no response from fan 8) Coolant becomes increasingly agitated and then boils out of expansion tank making a big mess - but still no leaks from anywhere else I do not know what to suspect first - any ideas would be gratefully received Many thanks :-)  
• Vauxhall Astra GTC - Only one symptom for blown head gasket? 20 Aug 2023 (Forum)
  Hi all, My coolant tank keeps cracking and then leaking. The car NEVER overheats cause i keep filling the coolant.  I had new WATERPUMP, THERMOSTAT, 3X COOLANT TANK AND CAP.  I dont have any of the other symptoms of a blown head gasket, but i think the increased pressure keeps cracking my coolant tanks.
• Ford Fiesta - Water Reservoir 27 Jul 2012 (Forum)
  My wifes 2003 Fieta 1.4 Ghia may have a problem. I've been topping the water reservoir up every week or so with coolant as it appears to have little left in it. We stopped today somewhere and I smelt hot water/coolant and saw the red liquid all over the floor. When I checked the screw reservoir cap it appeared cross threaded, so I'd obviously some how put it on wrong last time?
• Volkswagen Passat (1997 - 2000) - PD 115 BHP - coolant loss 4 Jun 2009 (Forum)
  I have to travel on a 400 mile round trip early tomorrow (100% motorway) and I am wondering if I should risk it? I have arranged a coolant system pressure/leakage check at my local garage on Friday. Any suggestions as to what may be the problem and if you would risk the journey? Thanks for any advice.

• Coolant leak - Seat Toledo TdiSE 2 Mar 2007 (Forum)
  Unfortunately when I do my regular long distance runs of 220 miles twice or three times weekly, the coolant level goes from the maximum line to the minimum line after each 220 mile trip. No oil lost just coolant. ( it still does near 60 mpg). My local main Seat dealer has now given up searching for leaks.
• Clio coolant leak 11 Jun 2003 (Forum)
  Just bought a low mileage L reg Clio from garage. Took it back straight away as clearly had coolant leak. Garage did pressure test and said "No it didn't". Had to drive a fair distance away and found coolant still being lost. Took it to the nearest Renault garage who diagnosed a "loose bolt just above the water pump; it's tightened and alright now".

  Coolant fan always running on my Focus 6 May 2012 (Ask HJ)
  The coolant fan on my car always runs even after a 10 minute drive.. It also runs after I have turned the ignition off for about 1 minute. Although...
