Engine coolant loss (2015 new model)
 

Hi,

I bought a 2015 XC90 last year. There has been a problem with engine coolant loss since I purchased it. The red light comes on. I have had it with the Volvo dealer on three occassions and I think they replaced the sump on the time. Anyway it light is on again this morning but has gone off since.

Anybody know anything about this problem?

The coolant is topped up by me when it goes down but it is either leaking or burning coolant.

Didn't the vea engine have a problem with the EGR valve cooler leaking, seem to remember something from the early V60 VEA engines.

If you have a D5 look at the radiator bottom corners as that is the common leak point.

Thanks. Could it be possible that the coolant is leaking into the engine?

Yes, that is always a possibility, if you have a dipstick look for signs of water in the oil, also look for scum under the filler cap on the rocker box and breather pipes.. it's not a failsafe method but indicative. Other alternate is get your garage to do a pressure check.

You have to look at a worst case scenario here , You have bought someone else's problem who knew exactly what was wrong before selling it to you ..., possibly cracked cylinder liner/s where the head seals ...

Thanks for that. There was a 3/4L loss of coolant over the last 2 months. we were onto garage today. They have looked at the problem and are surprised and said that they are now suspecting a head gasket problem. I bought this car in the UK from a "reputable" Volvo dealer. The catalytic converter also went about 4 months after purchase but that is probably hard luck. I have a Volvo warranty expiring at the end of next week. Any advice would be appreciated. I am based in Ireland!

Surely, if you have Volvo warranty, you can just give it to them, explain what's happening and say find and fix my problem and it'll be FOC?

I have it in again for the garage on Monday. Wouldn't like the warranty to run out and then have a major engine problem outside of warranty.

You need to take it promptly back , tell them how much you are topping it up , tell them you suspect the top of the cylinder liners might not be sealing and let them have it until they have fixed it . any warranty job they do is only guaranteed until the warranty runs out .. so they might claim to have fixed it and you find time goes on , warranty runs out and you still have the problem . They need to bite the bullet and get the head off after doing their standard cooling system leak tests .

thanks for that. I am taking it back Monday and will send an e mail in advance along the lines of your suggestion.
