‘03 190 started to lose/use coolant

Robti · 14th November 2019, 08:12

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.--

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

So would not panic yet.
