t680 winter front

Check manufacturer recommendations. Most of the newer trucks don't need them. I have a 2012 T-700 ISX15. I have plenty of heat without a winter front. And temp stays at 185*. With the new emissions a winter front can actually cause problems.

 

I politely disagreed with salesman about his stating a winter front wasn't needed ... He brought me to the head mechanic who stated that t680 owners using a winter front are seeing more engine derates due to high intake temperatures ... I'm still on the fence but have noticed in minus 20 my temps are still up in normal range .. Only issue seems a bit longer warmup time .. At 1000 rpm it holds 200 no problem so far the few times I idle

 

Call great west kenworth in calgary ab I just got one ordered today they said they work great and jight quality to +1 (403) 253-7555 here's the number for them.

 

I also heard that there is a temperature sensor located near the front of the engine that activates the heater on the DEF tank and lines. With a winter front, it blocks the air flow to that sensor and the DEF will freeze which will set off a malfunction light and eventual engine derate.
