2011 Volvo D13 Coolant loss
I have been running this 2011 Volvo with a 425hp D13 since it had 18,500 miles. It has been losing coolant since day 1, usually on a hard pull is when I get the "Critically low coolant level" warning. I check the coolant level daily, and top it off when it gets close to the minimum level.
The company shop has found two loose clamps and a leaking hose. So they say, I have only seen coolant on the ground twice and that was coming from a clamp behind the water pump. The shop would not supply me with coolant, and simply said to add water.
They finally sent the truck to Volvo after I added 2 gallons of water during a 300 mile trip from Vegas to Phoenix.
The Volvo shop in Phoenix removed the EGR cooler outlet hose and pressre tested the EGR cooler finding NO leaks. Then pressuer tested the cooling system and found coolant leaking from air compressor hose clamp. They tightened the clamp, topped off the system and pressure tested again finding no leaks.
5400 miles since leaving the Volvo shop, I have already added 2.5 gallons of coolant. (Finally convinced the shop to give me coolant instead of adding water!)
The shop is not willing to take an oil sample. Every time I put it in the shop to fix the coolant leak, they have it for 3-4 days and do not fix the problem.
Does anybody have any ideas of what I can look at so I can solve this problem and not have to worry about overheating? If the coolant is getting into the oil, and the company does 30,000 mile oil changes, how much damage is the coolant doing to this motor? Will this be an issue for me, or will the motor go 500,00 miles without any issues?
Is this a worthwhile discussion?
