Ford Ka - 2004 Ford KA: blowing cold air and losing coolant 17 Mar 2014 (Forum)
I've had my Ford KA for about seven or eight months now: it's a fantastic little car, starts up fist time without fail and runs like a dream. A couple of months ago I'd run a usual check on the coolant and oil levels and noticed the former was dangerously low: no problem I thought and topped it back up. I tended to do this once every two weeks (no idea if this is normal!). However, it has now gotten to the stage where I'm topping up the car once every three days, if not every day, as it is losing that much water. -

Citroen Xsara - Citroen xsara ? ECU fault 13 Jun 2012 (Forum)
they checked ECU for codes (there were about six of them) they cleared these off and i took the car back the next day and there were about six codes again. Two of them matched original codes one related to coolant temp the other causing the ECU to put to much petrol in the fuel mix which is the reason for the car 'coughing' they are convinced that the ECU is faulty because they have replaced the coolant temp sensor already. -
Peugeot 307 (2001 - 2007) - 2005 1.6 coolant fan & FAP issues 13 May 2009 (Forum)
Firstly could anyone confirm the 'HZC' in my VIN sentences me to this potential 'minefield' of expensive problems? secondly the fan (general coolant type, i presume?) seems to be on and off, on a regular basis, both with the engine on and off, long and short trips. Is that normal... what sort of frequency would you expect for FAP regeneration? -
Alpine pass experience 9 Dec 2008 (Forum)
Fourthly, and the main point of this post, the next morning I found that the engine had lost about a pint of coolant. There was no obvious sign of a leak anywhere, engine temperature going up the pass had been normal, outside temperature had been below freezing (it was actually snowing at the top). My guess is that due to the altitude change, the pressure cap (25 lb) had been unable to cope and had allowed some blow-off of coolant. -
Rover 75 (1999 - 2005) - 00 1.8 Remanufactured engines -WARNING 9 Oct 2008 (Forum)
A remanufactured engine sounded excellent but cost £1337.33 plus fitting by a local garage. After it was fitted, the car was losing very small amounts of coolant; an eggcup full per week initially. I couldn't believe the new engine was leaking so I replaced hoses and radiator - they were old, but no obvious leakage. Coolant loss started again. It got to half a cup to a cup a day by the end of September and I saw coolant running down the side of the block from the head. -
Bora 2.ol running probs/low mpg 22 Jun 2005 (Forum)
Next I checked the output voltage of the Lambda probes, mine has two, one on the exhaust manifold and one on the Cat. I recorded 0.010v cold and they both climbed to 0.023v when the coolant indicated 90 c(normal). The Lambda probes were fitted but the electrical plugs were disconnected when I tested them. Next I spoke to VW and they said the problem is usually the air mass meter or the coolant temp sensor. -
C'mon!!..HJ's Corsa test. 27 Nov 2006 (Forum)
C'mon Vauxhall.. Why no engine coolant temperature gauge? Why no mention of this omission in your roadtest, HJ? Surely (IMO) a critical instrument? I would not consider a Corsa purely for this reason. -

Pug 306 diesel, fuel temp regulator 29 Jul 2005 (Forum)
The fuel heater circuit is below the plastic filter housing (seperated by a large o-ring) and is cast into the base of the metal coolant heated base. Those with a haynes manual can see a pretty good picture of this in the diesel fuel/coolant section. The pattern of flow can be seen running between 11 o'clock and 1 o'clock (if it were the face of a clock), in a spiral pattern to maximise the heat transfer form the coolant circuit to the fuel flow circuit. -

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. -
Opel Mervia - Opel Mervia light grey/white smoke 26 Apr 2021 (Forum)
I’ve noticed more when it’s going down hill and I’ve reved it from 2nd into 3rd gear. It’ll puff out the white/light grey smoke. I read online it may be the coolant leaking into the head gasket. I’ve told the garage I bought it from and they filled the coolant more and said it’s all fine and it’s normal for the car to do so. Which to me a car doesn’t just blow out smoke.I’ve never had a LPG running car so don’t now if this is the norm.
