this should be a good way to exchange useful info!

I have a 2017 V90 (2.0L, I think it only comes in a 2.0) and flushed the engine with this stuff:

it is running smooth and I noticed less oil consumption. A family member ran it into the ground for only having it for 3 years or so, it felt like it was a 10 year old car!

also bought this

as the floor mats were worn out.
your turn!

I replaced the lower radiator hose along with a coolant change. However, I am having a terrible time "burping" the air out. I have searched forum but was unable to figure out what I am doing wrong re bleeding the coolant system. Any ideas would be greatly appreciated! John

Got a software update, related to DPF matters

I own a 98 V90 with 274k+ miles and I have the same issue with the cooling system. I took the head off last year and had to replace many of the original sensors. I have gone thru two gallons of antifreeze since reassembly- somewhere somehow the pressure builds up and the only way to relieve the pressure is to loosen the expansion tank cap. (When the engine cools) Driving three or four miles causes coolant loss but don't know where? No signs on the hoses or around the hoses. I haven't been driving it often lately because it needs a fuel regulator.
This cooling issue is a puzzle tho.

discovered a leaking head gasket which caused coolant to leak into cylinder 4 causing misfire, high short term fuel trim and constant loss of coolant.
fortunately the engine oil system was not damaged.
I replaced the head gasket and at the same time refaced the surfaces of the head and valve area where the oil seal lives, as there was a major oil leak in that particular area, caused by a defacement of the metal surfaces. Oh boy! not a BIG job but made me anxious....
