2004 Vectra: Coolant Capacity & Fuel Filters

FlyboyTR · 12-15-2021, 06:38 AM

I have started servicing everything on the new to us Vectra. Cummins ISC 350 HP.

I am getting a reading of 0.6 units of SCA! Obviously not acceptable! I find this odd being the engine was serviced 4 months ago. Oh well...that is easily corrected with a new filter and the addition of DCA4. Frankly, I don't think the shop was maintaining the coolant properly...

My new filters (oil, fuel & water) should arrive tomorrow. In the meantime, I decided to drain the ONE AND ONLY fuel filter to check for water (just curious, even though I will be changing the filter). I have the side radiator and the fuel filter is mounted aft of the engine (you have to reach down to access it). I drained about an ounce of fluid, no water. I had a difficult time threading the drain back in (working from overhead). I let the lift pump run a cycle and fired her up. All good. About an hour later I returned to the coach to do a starting amp load test. However, the engine would not start. I walked to the rear to find a large puddle of diesel on the concrete.

I slid under on the creeper and could visually see the drain was NOT seated properly. It took several attempts and pressure to finally get the drain to thread in properly. After that, I ran the key-on lift pump cycle for 5 times, then proceeded to crank the engine. No Joy! I ran the lift pump cycle 5 more times and tried again...still no rumble from the rear! I repeated this two more times, a total of 20 lift pump cycles to re-prime/fill the filter but the engine still won't start.

My assumption is that I have air in the CAPS (fuel injection pump). What is the easiest way to bleed the air from the system. It appears I will have to pull the bedroom floor up so I can access the CAPS. Thanks!

Hopefully, someone will come along to answer your questions. A great many DP owners have their engine serviced professionally and so there may not be a lot of personally experienced members here that can respond.

If you don't get answers here, I'd suggest posting your questions over on the IRV2 website. Winnie Owners is a spin-off from IRV2 and it's a vastly larger forum with experienced owners of all brands of RVs.

I searched for threads with "Cummins ISC" in the title at IRV2 and found over 1600 threads. I can't say if any of them are specific to your question or not. There is also a Freightliner chassis specific forum there.

Sorry I am of zero help with your questions.

UPDATE:
After sitting overnight, I primed her one more time and she started. It took about 2 minutes for things to settle down. But all is good!

I started on the cooling system, SCA. I now find that I have cracks in the purge tank. That has got to hold pressure! The leak is around the base of the fitting the radiator cap attaches to. Sigh... It's time for more research to find the best deal on replacing that.
