Can I replace a solenoid myself?
Parts range from under $30 to more than $400, but if you’re skilled with a set of wrenches, you can at least save the labor costs and replace a starter solenoid yourself. Replacing a variable timing solenoid usually takes 30 minutes to an hour, with labor costs ranging from $75 to $150. For vehicles with harder-to-access solenoids, the labor charges may be higher, and account for diagnostic charges on top of that.
Are VANOS solenoids easy to replace?
You can clean or replace the solenoids quite easily if needed. My suggestion is if you have determined you need a VANOS solenoid by cleaning or swapping side to side, replace both solenoids. They are fairly economical and you’re always better off replacing a degrading part. Repairing a solenoid valve can be a smart, cost-effective choice, especially for common, straightforward issues.
