      Installation Notes:  Approximate installation time is 4-5 hours (experienced mechanic times listed, yours may take longer).  Professional installation recommended.  Overflow hose routes on the passenger side. Longer hose & custom routing required if using an overflow tank. Drilling of radiator core support required. Factory fan shroud may not work without drilling & custom foam sealing radiator to fan shroud...our aluminum dual fan shroud recommended (P/N AMC-FS407).  3 & 4 core versions may not clear aftermarket clutch fans, aftermarket Sanden A/C compressors, & aftermarket serpentine drive systems. These applications may require using dual electric cooling fans & fan shroud.
