Attention: TDR Forum Junkies i had my tune-up with the cummins specialist. a couple of his comments were:
make absolutely sure the 2 solenoids under the port battery are good and tight. they control the intake air heater.
the injector pump solenoid almost never goes bad ($450). it is almost always the relay (on the firewall -buy seimens - cheaper) that controls it. engine won't start or hard to start are some of the symptoms.
unless there is frost on the window. no need to wait on the manifold heater.
if you want a quick start and ease on your starter, then give just a crack of pedal and turn the key. my engine starts with < 1 crank. i. e. BANG!
in extremely cold weather, give the heater 2 cycles and 1/2 pedal.
the proper timing for my truck is at 15. 5deg. the injector timing gear was never put on correctly at cummins because they would not remove the grease on the shaft place there by bosch. thus the gear was slipped. so he loosened the gear, set bdc, then put the gear back with 144ft-lbs.
don't waste your time having a dealer time your truck unless he does it that way.
use cummins premium blue oil only if that is the only oil that has been in the rig, otherwise use rotella t 15w40.
change your oil <5000miles. turbo should last 800,000mi.
be careful changing the fuel filter (before winter and every 12,000mi)- high risk for contamination and damage to the injector pump ($5900 retail). i. e. be anal.
valve adjustment every 200,000mi.
change coolant every 2 yrs.
oil should look coming out the way it went in if you change it every 3-4000mi.
my truck runs like a dream - he made right the recall 970 fubar'd by the dealer. tps voltgages all screwed up. dealer lied. linkage bent by the dealer. linkgage must also be adjusted for the 1st gear. can't be too short or too long. dealer was installing a brake switch when they had no clue as to why my trruck was surging. $140 down the tubes.
good luck. scott.
