VW G11 coolant. 1.5L bottle of Pentosin blue coolant / antifreeze. Volkswagen specifies phosphate/silicate-free antifreeze in all their vehicles. Most national brand antifreeze does not meet VW's specifications. German Pentosin antifreeze exceeds all of Volkswagen's requirements and is neutral to metals, rubber parts and sealing materials. Mix 50/50 with distilled water for best results. (Got brown VW coolant? Two colors were mixed - change it!)
Along with using VW G11 coolant, treat your diesel engine to our high performance fully synthetic oil. It provides superior wear resistance and reduces sludge build-up for improved engine life. Also, don’t forget your magnetic oil drain plug to prevent metal from traveling around your engine in the oil!
