Every now and again now (since a thermostat replacement) I seem to get a sweet coolant smell under the hood. Mainly after long drives. I’m not loosing any coolant but there is left over coolant leak around the ‘seam’ of the coolant reservoir. Nothing around lid but half way down the side of the tank it’s the residue.
just wandering what could be causing this. It may be coming from the lid but I can’t see. The lid and seal seems quite good. Could there be anywhere else on the car to look for possible leakage. Ever so slight but want to try to catch it early before it’s a needed fix down the track.
this is a 2001 V70 XC
