    Hi everyone
    After a 5 mile journey this morning, I parked up at the local supermarket and when I came back out there was a lovely puddle of coolant under the radiator. I thought it was a blown radiator but when I got it home (only 1/2 a mile away) the puddle is no more, neither is it leaking any more. The header tank looks normal, still has plenty of coolant, but it looks as though the overflow pipe on the header tank had sneezed a load of coolant out.
    What is likely to have caused this? Am I looking at thermostat, radiator, head gasket, or giving the car a course of Beechams Cold Medicine?
    It is a 2004 2.2 ICTDI.

    Was the puddle from your car or the previous one occupying that space?
    Was there any coolant visible on the underside of the engine bay/radiator?
    Were any of the hoses wet?
    Has the coolant ever been changed?

    Have you removed the oil filler cap and examined it?
    Is there any coolant in the oil?

    It was definitely from my car, there was splashes between the radiator and the engine on the hoses, and coolant dripping from the undertray. The breather pipe was wet on the end so it looks like it has discharged from there. The oil is oil, no mayo, the filler cap looks normal and the dipstick is normal. The hoses are wet but it is clear that it is only because they have been splashed by the breather pipe.
    I haven’t a clue when it was last changed, it is possibly due a change but it has been previously looked after by Honda themselves and a recent health check by Honda shown no issues with the quality of the coolant.
    The only place it looks like the coolant has come from is the breather pipe.
    My mechanic reckons it could be the thermostat, but so far it gets to temperature then stays there.

    Going trawling around the internet recommends changing the radiator cap before anything else. I have one on order now from Honda, should be in tomorrow. I shall try that first.

    are you mistaking it for drips from running climate control or A/C? I run my climate control always and always have puddles as a result.

    if the coolant overflow pipe is split then it would obviously leak from there. The quantity that you suggest says its more of a large leak. I would deffo monitor this, The other thing to do is get the car up to temperature, say on a drive, where you can observe what happens and be able to trace the leak.

    You can also pressurise the system with cold engine and check if it keeps its pressure and/or look for leaks when pressurised.

    agreed, you can buy a pressure tester for just this job. though, having a look on eBay they seem to be a bout 45 quid

    Sure, because it's difficult to spot a leak with hot engine. It evaporates quick.

    The problem hasn’t reoccurred, but to be on the safe side I got my mechanic to change the Thermostat. Well, he tried, but Honda recommended the wrong thermostat, as does GSF and Euro Car Parts. It has the old thermostat back in temporarily until next week, when the correct one can be sourced.
    Is the correct Thermostat for a 2004 N22A1 the Febi Bilstein 33457?

    That's wierd, I can't see Honda recommending the wrong part. Unless it was a labelling error. I know that does happen. Have you checked on lings honda parts website to confirm the part number and then put that part number into ebay

    According to Lings, the part number is PFKL404268 which shows up as clips on eBay, no other site recognises it. It looks the same on Lings exploded diagram as the Febi one, I am at a loss though.

    Ah, it seems that your not aware of the trick that makes the website display the correct part number. Basically you need to delete the _pfk from the addreas bar and it will then display the correct Honda part number

    I have given up and gone to Honda for the part. £48.57. Hopefully I will have more luck with the gearbox mount, the transmission fluid and the paint I will need for the next few jobs!
