FOLLOW UP ON REPAIRS- O2 codes

[ncburch22]

I took my truck in this morning to Bluff City Land Rover. The codes they were given were different from mine. I had gotten P-0159(defective oxygen sensor) pertaining to Bank 2 Sensor 2. The codes they got said I had more than one o2 sensor that was bad so they replaced both rear sensors. This was all done at $318.29

Now for the part I was sort of skeptical on. The tech said he was given a second code on a bad thermostat. Funny, I had them replace the t-stat AND housing on November 3rd. He claims the seal was leaking, but I had never gotten any indication of this so I demanded to come in the shop to see for myself. I ordered the t-stat from British Pacific online for $40 and brought it into the dealer for the fix. Needless to say, this cost me another $379.13. I had a grand total of around $720. Let's hope I don't get another CEL within the next few months.

When the coolant was put back into the truck, they added over the "fill cold" line. Is this because the coolant hasn't gone through the whole system yet, or should I be worried? I drove it home about 8 miles.

Air still in it but probably OK.

Here are a couple of good links re the thermostat and air bleeding. Too much coolant is better than too little. Keep an eye on the level.

Thermostat replacement.

i recently replaced my thermostat when they engine wouldn't get up to temp. if you are changing your oil, you could replace the thermostat. it was a pretty simple fix, also found a really good guide on disco3 if i remember correctly.

As far as your coolant level, i would make sure you check it when it is dead cold. The temp of that fluid has a pretty big impact on the level.

I think the coolant tank has an overflow sort of area where it would be pretty hard to overfill with any negative impact (might need someone to confirm on that one)?

Thanks guys. I'll check the cold level before I head out today. I had the housing, bleeder valve, and t-stat replaced in November. I'm not saying the LR techs did any wrong doing. I'm just worried they over filled the coolant. I don't see how they could if they did what the work order states, "Emptied coolant out, replaced t-stat, filled back up with original coolant". This should me the same amount went back in, correct? As Bbyer stated, too much is better than too little. As long as the pressure isn't too high as to crack the tank I'll be okay.
