Mike, what's going on? What do you think its happening? Did it over pressurized? What temps has your truck been running at?
This should should probably be a new thread but I'll give some of the details here; I won't know more until the weekend. I ordered a new Reservoir and Cap and they are supposed to be here on Friday. When I get them, I plan to install and then perform a gas/pressure test at the reservoir to rule out that. I had to cancel dropping the truck off at the welders because of this... *sighs*
The facts -
1. Truck overheated last Spring (red light did come on). It was shutoff immediately
2. I changed the Water Pump, Coolant Reservoir, Cap, Hoses, Tstat and Belt.
3. Circumvented the TB heater plate by just capping everything off and running it from my Intake Manifold directly to my reservoir.
4. Since I had it apart, I went ahead and changed shocks/springs, and SS brake lines (has nothing to do with this but it's still something that was changed afterwards)
After that, it gave the following: 1590, 1171, 1174 and a 0306. As a result, I performed the following:
1. Smoke Test on the Intake Manifold. I found air to be coming from my valve cover PVC hoses AND the TB Heather Plate, where I had only put on a vacuum cap and hadn't clamped them.
2. Hose Clamped those rubber vacuum caps
2. Bought a PVC Kit and Replaced those as well as the baffle
3. Restarted and ALL the codes went away after a Drive Cycle, but were stored.
Took it over to the welder on Friday and he took the measurements and we planned for me to bring the truck back today for completion; however, I stopped at the Grill for 30 min and came outside to find a nice puddle on the ground. Opened it up and couldn't see where it was coming from but noted I had half a reservoir of fluid left and my house is only a mile from that Pub so I elected to drive it home real quick. Did such, put it in the garage and found the leak. Ordered the new part, cancelled my bumper appt, and am patiently waiting - but going through all the worst case scenarios in my head...which include buying a used motor and rebuilding it.
