It finally happened.
Waited until the coldest, busiest week of the year, but it finally happened.
I added a coolant filter around 83K miles and the truck has 113,243 on it today.
Pulled into the parking lot at the office, turned off the radio, started backing into the parking spot and heard the noise from under the hood.
I was hoping it was the tensioner, but alas twas not to be.
It would have to be this week, too. My daughter is sick (104.7 fever last night); my wife is getting sick; one of the boys is getting sick; the company Christmas party is tomorrow night; and it's the coldest week of the year to date - going to be in the 20's tonight and get colder through the weekend - mid-teens with wind chills close to zero.
My plan is to have the company's contract mechanic do the work. He's extremely capable and spent 10 minutes with me in the parking lot this morning making certain that's what it really is. If I didn't know how well he keeps our fleet of 30 vehicles running I wouldn't trust him.
Already have the 203* t-stat and the dual alternator upper radiator hose, so don't need to add those. Will replace the serpentine and keep the existing one as a spare. Have Fleetrite ELC in there that is only a couple of months old. Plan to keep that too.
What else do I need to consider while this is being accomplished?
