Another GM 4.3 Thread.

My 2006 truck, with just 74k km(47k mi) quit on me and I had to get it towed home.

Testing showed the Ignition Module had burned out, so I put a new one on and the truck is running well now.

I am ordering some spare parts from RockAuto and I am going to buy a spare module to keep in the glove box so that if it ever happens again, I can just plug in the new module and be on my way. The new module can be plugged in in less than a minute.

I am getting a Gates Superstat thermostat since the engine is running a few degress cooler than it should be. OE and a replacement Delco stat both failed at around 24k mi of use.

Should I get a spare Crank Sensor? Anything else I should get that commonly fails on this engine?

My 1996 has about 270,000 miles and 2004 about 127,000 miles and while I bought the 2004 with 118,000 on it (and everything seems OEM) I've never had ANY problems with either of the 4.3l.

The only thing the 96 has needed other than normal (oil changes, plugs, coolant, belts and such) is a thermostat and spark plug wires. Everything else is the same.

The 2004 so far has gotten spark plug wires, cap and rear O2 sensors.

I'm not aware of anything "common" that goes with these engines. Some of the older ones do need the intake gaskets done but so far both of mine have held.

Take care, Bill

I didn't mention the fuel pump in my OP but I plan on replacing it at about 130k km(80k mi) instead of waiting for it to strand me. I won't get to that mileage for another couple of years.
