‘15 VNL 630 w/ D13 “Poor DEF quality”

Yes that’s true but from what he is saying he eliminated that possibility. So what else could he do next. The filter if he hasn’t changed it would be the first.

Yes I did see more than a few people putting plain water into their def tanks. I just laughed.

 

I am just glad I don't have this system to contend with. We had five Ryder trucks with them up in ND. Out of those five trucks, only one would work at any given time. DEF tanks continually froze solid in the winter. What a PIA.

 

A friend bought a new Kenworth and had it up in Manitoba in winter. He didn’t order it with a dpf tank heater and it froze solid. Had to have towed back to Winnipeg and they replaced the tank as it cracked, the pump, the line. Cost him almost 12000.

 

Changing the DEF filter should be done annually.

 

I know, these emissions are criminal in my book. Just the monies the EGR/DPF system have cost me in repairs and downtime, it is just not worth owning one of these trucks. Thank God I was able to rid myself of the issues several years ago, but the rest of the truck has been so cheapened to make up for the R&D monies... Just a non stop nightmare. Just putting mine back together in the driveway, heading out to finish the job here shortly. Going to be 58* here today! Been in the 20's since last week. Hard to get ambitious in that weather, and takes forever for the paint to dry on the motor and components.

 

try to replace both def filters also remove def doser and check if there is build up int he flex bellows between scr and dpf, this would be the first step before any kind of serious money is dropped in emission system.

 

Good idea. You mean the filler neck filter and the def pump/tank filter?

 

yes but there is one more in the supply line to the pump

 

Well I have question and can't seem to find an answer. Getting a truck in couple of days that was sitting at dealership for almost 2 yers they did say they started it every day.....but who know
Any ways I think I should drain and clean the def tank on this volvo d13 put new def pump filter ,nozle screener and inline filter. But I couldn't find any info how to and what to clean dpf tanks with hot water ? Then rines and repeat a few times may be .truck was sitting in California those hot summers and as I learnt def fuel not spouse to be stored for even couple of months let alone 2 yers .
Any insight help or advice would be appreciated thank you .
