The BD-Power 1081160 Cool Down Timer 2 eliminates the problems of shutting your engine down after a heavy haul when the exhaust gas temperature (EGT) is above normal. This can result in turbo bearing damage, but now you can protect your turbo with BDs Cool Down Timer (CDT). The CDT works with any K-Type EGT probe commonly found in most pyrometer gauge kits and has adjustable shut down temperature setting. Plus, five-minute timeout and quick shut down functions. The new design of the CDT adds increased troubleshooting ability and new installation features plus the ability to work with vehicle security alarms and in reducing regeneration of the DPF on 2008-up vehicles. Temperature shutoff requires the purchase of the EGT Probe (sold separately, see below).
