Replacing cooling system components and performing a proper coolant flush will ensure a long life for your cooling system. Most of the cooling system components are exposed to very high temperatures and repeated thermal cycling. Heat-hardening causes warping and cracking that leads to coolant loss and possible engine damage from overheating.
DEI's Radiator Relief™ Cooling System Flush is a concentrated cleansing agent that effectively removes rust and mineral deposits left behind in the radiator core and lines, and also dissolves oily residue build-up left behind in old anti-freeze and coolant mixtures due to external contaminants.
Avoid headaches altogether and replace all problematic items at once to keep your cooling system running efficiently.
