When I referred to the Red Stuff in my previous post, I was not even thinking of the typical store shelf Dexcool or whatever. The stuff I use in my CRD is the same stuff I use in the Cummins in my semi. Cat EC-1 is one of the labels it goes under. Delo and Shell have this specific diesel engine coolant as well. It is HOAT. The stuff went thru 350,000 miles in my semi and looked great. I decided to flush and fill with new ELC coolant when I had to replace a water pump that developed a cold leak (heck, had to drain the block anyway). Cheap insurance. It was factory filled with Shell Rotella ELC coolant (same stuff as Cat EC-1). Since there are many similarities between modern semi engines and the Liberty CRD engine, specifically the wet sleeved cylinders, then it seems warranted to use the same coolant that large diesels use and is specifically formulated to protect wet sleeved cylinders and aluminum heads. Not sure the stuff on the typical Wally World shelves is the same stuff (at the very least, I haven't seen this stuff on Wally shelves or even home and farm stores in my area and the auto parts stores didn't carry it). I get all my coolant from heavy truck supply outlets or dealers. The Duramax and Powerstroke diesels are not wet sleeved, so they do not have a problem with cylinder liner cavitation. The CRD will have the same issues as heavy diesel engines which are wet sleeved. Since it is extremely expensive to replace the cylinder liners in a CRD, I didn't want to take any chances. So... the CRD gets the same coolant my semi gets. Didn't even bother to consult Chrysler/Jeep on the issue. I go by the standards and recommendations of the Technology and Maintenance Council... the hands down authority in the transportation industry and recognized by ALL diesel engine OEMs.

Like I stated before, take the information for what you think it's worth. No skin off my back what coolant you choose. If you feel comfortable using green, then by all means do so. I brought this up only so some would at least research out the issue before just throwing any 'ol coolant in their CRD. Of many things I would be willing to save a buck on, coolant in my CRD is not one of them, just like in the $25,000 engine in my semi. And it was not much more expensive to flush and fill the CRD with the ELC coolant. Barely noticed the price compared to many other costs associated with the CRD.

Are you saying there is miss information floating around on the internet? Not possible! If its on the internet or you read it in the Enquirer magazine its all 100% true haha.

(I think that's what folks mean when they talk about cavitation)
