Coolant Issues

So I have changed the recovery tank to a metal tank and have been preparing to do a flush and coolant change. Wanted to switch over to the extended life coolant. Cummins says no issues. Freightliner says do not do it as it causes the sensor to malfunction. Any advice or experience with the issue. my 2005 Vectra has the 8.9 Cummins ISL engine.

Very odd to hear that from Freightliner. The long life coolant is less corrosive than the old green antifreeze. It will be less likely to affect the sensors. That is why it is long life. What manufacture/make antifreeze did they recommend?

I forget the exact name but it is the fleet guard that has to have the sca added. The person I talked to said he was going to contact Cummins because they have heard this from more than just me. I believe I have seen plenty of people on this forum that says they have changed to the extended life coolant, but have yet to hear of the issue with the sensor

wstalker,
Just wondering, is your coach a rear or side radiator? If it's a rear, and you stated you changed your recovery tank to a metal one, do you by any chance have pictures? If your coach is a side radiator, my question doesn't apply. Thanks.
Scott

Roger that. I was wondering since you stated you went to a "metal" coolant recovery reservoir vs the plastic. There are no such thing in the rear radiator unless one is custom made.
