• coolant leak protector 1 Jul 2003 (Forum)
  IIRC the guy said the fluid should simply be added to the cooling system and could be left indefinitely. It would seal any leaks immediately and remain active until the coolant was changed. Anyone had any experience of this product and/or got any views on it ?
• OMEGA 2.5 Coolant Leak 13 Mar 2003 (Forum)
  I have a coolant leak at the rear of the engine on my 1999 2.5 V6 Omega although it is only minor and doesn\'t necesitate frequently topping up the reservoir. The leak runs down the back of the block on the offside, adjacent to the gearbox leaving a very small drip on the garage floor but is only apparent once the engine has cooled down.

• Ford Fiesta 2001 - Heater Control Valve 19 May 2018 (Forum)
    So my 2001 Ford fiesta was only blowing hot air, and after a bit of research I decided to replace the heater control valve.    So, I drained coolant, replaced valve and then refilled coolant.    The good news...

• 2001 Fiesta mk4 endura-E 1.3 - 2001 Fiesta operating temp? 9 Aug 2019 (Forum)
  I live in a hot climate ,ambient temp here is around 35-37C the car doesn't overheats and the temp gauge is always just slightly above the middle when the engine reach its operating temp, when I enter the hidden menu I can view the coolant temp: so engine warms up until coolant temp reaches 89c and then I can see a drop in temp as the thermostat opens while driving at highway speeds or to say above  30-40 mph coolant temp is around 92-96c at very traffic or very slow driving coolant temp  can go up to 110c, radiator fan kicks in at 105c though so , i would appreciate if someone who have/had this car can tell me if this is normal and what their coolant temps are so i can compare to mine thanks in advance Harel  
• Golf gt tdi 02 - Leaking coolant 22 Jul 2012 (Forum)
  Ok have a golf that's leaking coolant, had cambelt replaced as 20k done since last, and then put in a new water pump and cap When I say leaking it isn't noticeable I can't see any water and it is a tiny amount, it falls just below the minimum every week or so Cambelt was replaced 3weeks ago and it flashed up today check coolant for the first time in 3 weeks where it needed a small top up Obviously this is a sign of gasket but there is nothing to suggest it is this, no milky oil etc I was advised by the garage that it could be the coolant tank?
• Peugeot 206 1.4 Petrol - Dirty brown stuff inside coolant reservoir 16 May 2019 (Forum)
  Just got this car and noticed that the coolant reservoir is dirty with dried brown gunk around the sides.  Also the oil on the dipstick is a lighter brown than I'm used to seeing, viscosity seems normal though.   Is this likely a head gasket about to go and stop driving it now type scenario?

• Fiesta 1.4 petrol Ghia '04 - Engine Coolant Leak 4 Jul 2014 (Forum)
  My header tank is going from high to low in a week, I looked under the front of the car and there is a coolant leak coming down from behind the oil filter, very slowly dripping off the oil filter. My garage pressure tested the system to 1 bar and couldn't find a leak! 'I can't repair a leak I can't find' was his reply.

• Nissan Micra (2003 - 2010) - 04 1.3 What colour antifreeze coolant should I use 14 Feb 2010 (Forum)
  Should it be blue or pink? The looklet just says L250. The coolant in there needs changing as its gone a rusty brown colour. Probably not changed as car has only done very low mileage. Appreciate any help or in a car this age does it matter so long as the anti freeze meets BS standards.

  At the beginning of August 08, my Ford dealer topped up my coolant level (the orange antifreeze) to the maximum mark. Since then the level has gone down to about 3/4 full. I am obviously concerned that I may have a leak and if not how else could the level go down ?
• Rover 45 (1999 - 2005) - 51 reg - Loosing Coolant following overheat 10 Oct 2007 (Forum)
  Have a Rover 45 51 plate. About 2 weeks ago it overheated on a short motorway journey. Have topped up with coolant ever since but now seems to be drinking the stuff.
