Diesel RVs: [diesel_mercedes] Easter Sunday

As Nate mentioned, we went looking for a wagon door to fix the window in his 300TD. No Joy.

Afterwards, just before the sun went down, Nate finished the flush job on my 300SD. It has been running for 3 weeks on fresh anti-freeze, after he did the citrus flush and distilled water reflush, getting out tons of junk. But in that three weeks, the anti-freeze has turned very dark and opaque, strongly suggesting that the flush had loosened stuff up but not gotten it all out.

So, he drained it, and it came out full of mud. Pulled the radiator hoses off and flushed and back flushed the radiator, more mud and gunk. The flushed and back flushed the block, more gunk and while back flushing, a lot of foamy suds from the citrus residue.

After a lot of just hose flushing, he filled it a few times with distilled water and I ran it up the hill and back. Finally, we refilled it with anti-freeze.

During most of the operation, he kept the aux water pump running, to keep the heater core flushed as well.

One of the problems he spotted last time was that the hose bib on the thermostat housing was corroded pretty badly. While walking the yard, we found a better one, with a good looking thermostat in place. He slapped that on after flushing the block.

Now I have put 100 miles on since the flush and the temperature hasn't yet reached "80" on the guage. Mostly it hovers between the hash mark at "40" and the one just above that. I'm beginning to wonder if that 'new' thermostat never closes?

I have to sa that all the gunk that came out the flush job occupied a huge volume. So I'm thinking that he flushed it up toy at least a 3.5 liter engine. Maybe even a 4.2!

After the flush, the odometer clocked over 348,800 miles. Still a lot of original parts still ticking away there.

Today, while Nate was chillin with Shirley out in Fontuckey, I wandered through the yard at the intersection of the 110 and the 91 freeways. Not a single 300TD in the place. Several 126s and more recent sedans and convertibles, and one 116SD. But not one 123 in the whole yard!
