Other GM Truck Problems
Check for other GM truck problems and cures on The Diesel Place forum site on the internet.
1) My injectors where replaced about 50,000 miles ago with an extended warranty, but at the time my dealer
did not change the fuel filter, which caused the engine to come to a dead stop with out warning, 2 months later( I would have ever deamed that they would not have changed the fillter during the repair, you can't trust any one!). GM finally has a recall to install a new design filter. Since my first diesel, 15 years ago, I always travel with extra fuel filters. With our Wanderlodges, I have actually changed filters on the road, wright at the diesel pumps, I had very acturate fuel filter guages on the dash of those coaches. Many times I have though about adding a Raycore Fuel fuel filter & guage to my truck (they are also avalible with fuel heaters))
2) A major problem with GM trucks is the constant wearing out of front steering & suspension componets (pitman arms, idler arms, tie rod ends, & upper control arm bushings) I also replaced the front wheel bearings at 80,000 mi , myself (bearing= $500.00 retail or $325.00 whosale). Everytime you change front end componets, you have to get a front end alignment, more$$$$$.
3) Also last Spring on the way back from Florida, my low coolant lite came on. It took me 2 months to find the pin hole leak with a pressure test.
A small 1/2" about 3' long balance cooling hose is hidden and buried at the front of the engine, just above the water pump. Its placement mades you think that the water pump is starting to leak.
Anyone getting close to 100,000mi or 3 years old should have this hose replaced.
