In the event that You're remaining at the front guard of Your 2008 Chevy Avalanche and taking a gander at the motor compartment,the oil pressure sensor will be on the upper right back corner of the motor. To get to it,You should eliminate the admission complex first. This substitution will require an oil pressure sensor attachment and a force wrench,the two of which can normally be leased from a sections store. On the off chance that You pay to have this part supplanted in the 2008 Avalanche,You can hope to pay somewhere in the range of $260 and $310. Work makes up about $180 to $230 of that cost. In this way,You can save a lot of cash,on the off chance that You handle the help work Yourself. By and large,eliminating the admission complex and changing out the sensor requires around 2.5 hours.
