I love my car but a woman can only be pushed so far.....& I’m right on the edge!!
Last weekend I noticed my coolant was just below min ... so being the good little girl I am I promptly topped up to just below max ...... I checked it today & it was below min again F,in great.... I taped the line I filled it to as I ran out of coolant ... just been to check and guess?? Yup below the min line!! Checked the cap seems fine? I can see down in the bowels below liquid (prob) coolant .... who the FXck knows!!! Is it poss a seal that’s gone? It’s so hard to check as limited space ... I guess it’s a trip to garage in morning then [emoji174][emoji36]
 
IMG_2288.JPG best view I can get I see liquid at bottom loosing so much coolant .. must be a hole in a tube or something??
 
Sounds expensive ����

Thermostat is near the battery and if required is only about £16, if you can safely park the car half on the curb, this gives you more space to look from underneath? assuming the leak is near the base of the rad, either hose, coupling, or rad itself or seals, non of which are hard to sort for the DIY person, ideally you need to get underneath to find the exact source of the leak? Plastic failure could be high on the list.

Rad if required is only £45

Bottom hose £8

Note too the metal pipe that runs behind the exhaust manifold also rusts way causing leaks ; https://www.ebay.co.uk/itm/RADIATOR...e76594f:g:5PAAAOSwnJpcp2YI&LH_ItemCondition=3

I’m defo up for getting under the car at least if I can find the leak I’ll be happy [emoji2] even happier if I can sort it myself!!!
 
My guess is radiatore. My Stilo and my old Alfa 145 both had a similar sly leak around the bottom of the radiator mount.

For the '45 I checked that there wasn't a leak anywhere else.. but the factory fit clamps don't ever come undone... a bit of fluid on the pipes can seem to be a leak from the joint (and had me foxed...) but it had actually run along the bottom of the radiator from a split in the radiatore. It only leaked under pressure, so wiping everything and waiting for a drip to appear from somewhere didn't show any leak.

My Stilo started the same way and I initially only noticed a slightly leaky water pump.. and that's where most of the fluid was collecting... but I was in Paris at the time so no chance to do more than just top it up. Then one day the temperature touched 38C and I was stuck on le peripherique ring road, which was too much for the radiatore and it started really pissing out.

Luckily, I found a Fiat garage with an Italian mechanic who spoke French, so I explained to him in Italiano what was wrong and he phoned up a local place that could fit me in and passed on the symptoms in French.

I learnt "pompe a eau" and "radiateur" .. which slightly offset the €1200 cost of having a pump, cam-belt kit and radiator fitted "bloody rapide, por favor" so that I could still get back to Calis in time for my ferry... Missed it by an hour due to a traffic delay (migrants climbing the fences.. :D ) and had to pay an extra €11 to change the ticket... but on the other hand, the Younger Mrs S. still laughs about it (I can still only cry) to this day, so I suppose it was "memorable".

Anyway, it's le radiateur, sans aucun doute.

Well my coolant level below min again after a trip of 17 miles been under car with torch ect and cannot find any signs of a leak from any pipe any ideas???



If it’s a pipe that has nothing underneath then it might not be hitting anything, top it up, run the engine up to temperature then get underneath. With a warm pressurised system that’s losing fluid that quickly you must be able to trace it with the engine running.
