‘03 190 started to lose/use coolant
 

Hi over the last couple of months I have had to top up my coolant weekly by a couple of tablespoons. Nothing to see leaking and no stains in the Vee. I thought at the start it might be the cap but no stains around it. So any where else to look ?
Thanks

I fixed my mystery leak recently.
The top hose has a protective sleeve where it passes over the g'box & under the airbox. It had a small split under the sleeve. Only spotted it by shining a torch round the engine while it was hot and running at night - that way you get to see the faintest bit of steam :¬)

Search for the stain that the coolant leaves as it evaporates.

If you can't find any stains it could be the start of head gasket failure.--:eek:

I always understood that HGF on the V6/190 was uncommon - have lost count of the number of posts about coolant loss on the V6 which usually concludes O ring failure on the stat/hoses or failure to properly follow MGR coolant refill process:shrug: So would not panic yet.

It is very uncommon Martin.

Will keep an eye on it and only doing a <4 miles a day atm visiting my mother, thanks for the replies ����

Could also be the lower coolant pipe that runs across the front of the engine. Mine had started leaking there. It's made of steel so ended up rusting - all good now

Going to pop the air filter housing off and run it up to temp and have a look and see if anything pops out for me to see

I had a mysterious coolant loss as well having to top up frequently I could not see anything leaking anywhere I thought the car was using coolant but one day I spotted what looked like dried coolant around the expansion tank with a faint sense of moisture around the cap so I popped I new cap on haven't lost any coolant in 2 weeks so far so I reckon it was just a failing radiator cap my p38 range rover which uses the same cap had also a mysterious coolant loss which was also attributed to a failing cap so might worth having a look edit: in my range rover you could also hear a very faint hissing if you put your ear close to the cap when switching off the engine after a nice long run
