what is the point of a grid heater delete?

 

Open up the intake side, and reduce the draining of your batteries during grid cycles

These Cummins engines dont have glow plugs to aid cold starts. The grid heater will heat the incoming air to ease cold starts. The grid heater delete will eliminate the grid heater and allows about half a pound psi of additional boost, at higher RPMS. Unless you have mucho mucho horsepower, and youre looking for every ounce of additional boost, removing it is futile. It does not really restrict airflow during normal everyday driving or towing. There is some info online regarding airflow testing with and without the grid heater. The difference is really insignificant. Check it out for yourself and you be the judge. I still run mine, as do many others.

 

ill be keeping it on right now then...rather have a easier cold start

 

I have the grid heater delete an haven't had any problems with it starting on a cold day. So far the coldest it has been was 17 degrees Fahrenheit though.

 

The commonrails do very well without grid heaters unlike earlier 5.9s. Sub 0s shouldn't be a problem other than a little white smoke.

 

When it gets really cold out here, I will usually plug in the block heater. It keeps the coolant temps at about 140*. Makes for real easy starts, plus I dont have to baby it until it warms up. Just get in and scoot!

 

My truck doesn't get over 140 with my block heater. Could I have something wrong with it? Mine starts easier when plugged in but not that hot.

 

Mine would barely show on the temp gauge when plugged in (around 100 degrees)

 

Well, reading the stock analog gauge, the needle is usually on the 140* mark. Im not sure just how accurate the stock gauge is. To clarify, its give or take.....ish....right around there......approximately.....in the area of...
