​
Diagnostics First, Parts Second
Many vehicle symptoms can have several possible causes.
A trouble code does not automatically identify the failed part.
A misfire code does not automatically mean an ignition coil is bad.
A battery that repeatedly dies does not automatically mean the battery itself has failed.
A catalytic converter efficiency code does not automatically mean the converter needs replacement.
Kool2U uses testing and diagnostic information to determine the cause before recommending repairs.
