High pressure in coolant system???

What's the number to that tech?

 

Keep us updated on repair!

 

I have this problem too with my 08. Driving me crazy and has already cost me a lot not to have it fixed. Please share his number. I'm doing a Sacramento run soon and sure would love to get this solved.
Thanks!

 

The problem came back up. He refunded me $200. I replaced the coppers again since there was exhaust marks. That did not help, I noticed that my temp gauge is always higher than normal, and fan kicks on around 210. I will have a electrician reprogram the computer, since that and the water pump are the only possible options left. I will let everyone know in 2 days if the problem was the fan turning on late.

 

He charges around $600 for labor to do coppers and around $200 parts. Since the water problem is usually the coppers but he will know better.

The issue seems to have been temporarily fixed. I am guessing you have a bigger problem than you think. Bubbles, addition of coolant and temperature running higher than normal. I would suspect a head gasket. Look at your stacks when you crank the truck. Check for white smoke. Thats my guess. I could be wrong.

 

I set the computer to activate cooling fan at 194. Truck temp now is always right in the middle. So far 5k miles with steep hills and didn't add any coolant.

 

I have 2010 Volvo 780 D13 485. I would lose very little due to EGR cooler, but when my top radiator hose blew on a hill, I had a spare because the first one was changed already and bought the second just in case. Didn't have antifreeze with me do used about 32 bottles of water to get to a TA. Brought 2gal pure. It started leaking out the hose I replace, so tighten it more, then it started with other hoses. Tighten those and fixed the leak around the bottom hose and over flow. Went through several bottles of antifreeze since then. I told a mechanic when getting a PM at a TA. He said that there should be a valve from the compressor before going into the coolant. I wonder if there is one and if it could be the problem?
On another note, several months ago we had truck in a volvo shop. Was there for over 2 weeks cause wouldn't regen due to check engine light. We spent money and always in the shop for this DPF system. Had new injectors put in, and more. This last time we called and complained about the time in shop. 2hrs later we get a call truck I'd ready. From that day till now our truck hadn't Regen once. Ask and soot stays around 2%.
I was going to call them back, but I thought why? It'll just keep costing us money. I do smell it coming out the back somewhere and assume it's a leak in the EGR cooler.
I've bought 3 other used trucks in my career with little or no cost, but this one is the first with the DPF crap and we've spent over 35,000 on BS stuff not counting maint, tires, breaks. Plus we still have one year to pay on it. Every time we go home it has to go in shop for something and that's not counting the repairs I can do at home. Our first and last Volvo ever!

 

Have you ever replaced your air compressor? if not, I suggest you do so, that may be what is causing overpressure to your coolant system.

 

wath ypu think is the problem
