Two questions on older trucks, what are the signs a rebuild is needed? and how do

Rebuild everything! If you buy a glider you must pay taxes on a new truck. You can't get 8 MPG out of a 379 with a 500 CAT, so that's not the answer. Avg on mine @ 32 K was 6.8 to 7.2 Sea -BALT

 

when i did my training. in 1999. the 2000 FL my trainer was driving. averaged 6.3 with a reefer. going from the rocky mountains to south carolina and back.

 

Don't buy anything aver a 03. after that there all junk. because of the EPA. Look for smoke from the stacks.(white or black). oil in the radiator or water in the oil. But most trucks will be clean up and fluids change. watch for soot from the stacks at start up. Buy a scan guage D. you can plug it into the truck and get fault codes, MPG, Mileage ect. Get the vin and do a truck search to see if it was in a accident and who and how many owners. If there isn't any receipts to show repairs, it kind of hoping you made the rite chose and see what happens. Try Damiron.com I bout a truck thew them. good trucks, Good people and a fair deal. Good Luck

 

What's a good price for a scan gauge?

 

No. egr started in 04. but look. there may be some late model 03 listed as 04. make sure it a scan gauge Diesel. new, around $150 give or take. you can get them cheaper on ebay used

 

I can get one at advance for 110 plus tax. I just wanted to make sure it was a good buy.

 

$110. buy it. good price. If you dont mind waiting. check ebay and Amazon. you mite find it cheeper. just look at shipping cost.

 

That is probably the scangauge E. You need the Scangauge D ($160) or Scangauge KR ($200)
