High heat or extreme cold is exactly what synthetic oil shines in!
Synthetic oil doesn't break down in the heat like conventional oil will.
15w-40 conventional oil in a Volvo has caused many people lots of problems. Soot packing is just one.
If you still desire a 40wt oil, the preference would be 5w-40 synthetic.
Bingo, case in point !!
Thumbs up !!

Another possibility is sticking EGR valve (open) causing high flow through the cooler and heat saturation of coolant. This is also bad scenario because a cracked cooler will follow soon usually.
Have you seen any high EGR temp codes?
Pushing coolant is why it's getting hot, you're displacing coolant with air....most likely case.
Hopefully it's not a HG.bonous Thanks this. -
Side note.... Put a manual fan switch on the truck ASAP ..

Update:
It seems the work I did have solved my overheating problem. It’s been over a week and all good. Running much cooler and watching the oil temp up hill with 42k it never went above 230. The fan kicks on at 210 and goes off when it suppose to, it not staying on forever like it was doing. Installed manual fan switch but honestly I haven’t had to use it, yet still glad I installed it, kudos to KB3MMX!
I will post if anything comes up in relation to this problem and I hope this helps out someone with similar problem.KB3MMX Thanks this. -
