How do I identify my GM rear differential?
The rear cover’s shape and the number of bolts are identifying features for GM rear differentials. The round 10-bolt cover with a bulge for the ring gear identifies this axle assembly as an 8.5-inch 10-bolt. The two lugs on the lower case at the 5 and 7 o’clock positions are also identifying features.
What rear end does my Silverado have?
Identify your GMC or Chevrolet rear end gear ratio by the RPO Codes, usually located on the placard labeled “Service Parts Identification” inside the drivers door panel or glove box.
What side is Bank 2 on Chevy Silverado?
Bank 2 sensor 2 in a chevy silverado is located on the passenger side behind the catalytic converter.
When should I change my differential fluid Silverado?
How Often Should You have the Differential Fluid Changed in Your Chevrolet? Generally speaking, differential fluid should be changed anywhere from every 30,000 miles to 60,000 miles.
Is 3.42 or 3.73 better?
The 3.42 is fine for towing smaller boats, plus you will get better gas mileage for everyday driving. If I were towing frequently on hilly roads, I might would go for the 3.73 for better gas mileage while towing, but the 3.42 should be fine with a 205.
How do I identify my differential?
Without an ID tag, differentials are identified by the number of cover bolts, the distinctive shape of the cover, the number of ring gear bolts, and ring gear diameter. They can also be identified by whether the center section is an integral or dropout design.
How much horsepower can a 10 bolt rear end handle?
7.5” 10 bolt GM rear: It will take up to about 450 HP IF the axle tubes are welded to the housing and either a differential cover with preload bolts is installed or straps are installed over the carrier bearing caps along with longer bolts.
How do I identify my G80 differential?
look in your glovebox & you’ll find a label that has a bunch of 3 digit codes. they’re in alphabetical order. Work your way down & over until you see G80.
How much HP can a 7.5 rear end handle?
Weak pinion gears. The 7.5 can take about 250 hp with a auto trans and last a good long time.
What side of engine is Bank 2?
Most commonly, bank 1 houses the front most cylinder on the engine cylinder 1, and bank 2 is the opposite side of the engine.
How many O2 sensors does a Silverado have?
There are four O2 sensors in 1999 to 2006 Silverado models: two upstream and two downstream sensors. The upstream sensors are located between the exhaust manifold and the exhaust, while the downstream sensors are located after the catalytic converter.
Is bank 1 sensor 1 upstream or downstream?
Sensor 1 is the upstream oxygen sensor. It is the sensor that measures the oxygen content in the exhaust, providing an input to the computer, which determines how to adjust the air/fuel ratio. Sensor 1 is the sensor closest to the engine. Sensor 2 is the downstream oxygen sensor.
What happens if you don’t change differential fluid?
Most differentials need a fluid change at about 50,000 miles. If left too long or if the fluid starts to run low, the differential will become noisy and can eventually fail. If that happens, the gears can seize, locking up the rear wheels and potentially causing a lot of damage or even an accident.
Does changing differential fluid make a difference?
Because the differential is at the rear and under the car, it gets none of the star treatment that the engine up front does. But if lubrication in the differential fails, you won’t be getting very far for very long. Fortunately, you only need to change this oil every 30,000 to 50,000 miles.
Can you use 75w90 instead of 80w90?
SAE 75W-90 maintains a more consistent thickness, or viscosity, across a wide temperature range. It’s thicker when exposed to high heat and thinner under colder, wintry conditions than 80W-90.
