Over the years cool­ing sys­tems have de­vel­oped from pretty ba­sic set-ups to elab­o­rate and so­phis­ti­cated mixes of metal com­po­nen­try, hoses, clamps, and sen­sors — although there hasn’t been much in the way of break­throughs in coolant tech­nol­ogy. We re­cently learned, af­ter it had blown up at SEMA last year, about Pre­stone’s Cor-Guard In­hibitors coolant. It looks like any other coolant, sure, but a bit of dig­ging and a scan over test data shows that this may ac­tu­ally be the first real ad­vance­ment in coolant tech­nol­ogy in the last 20 years. With seven years of devel­op­ment and a 15-patent-strong port­fo­lio un­der its belt, the lat­est from Pre­stone be­gins work­ing from the get-go, whereas tra­di­tional Or­ganic Acid Tech­nol­ogy (OAT) coolants can take “be­tween 5000 and 10,000 miles (8000km and 16,000km)” to kick in ac­cord­ing to the Vice Pres­i­dent of Tech­nol­ogy for Pre­stone, Colin Dil­ley. That’s pretty damn im­por­tant when you think about it, when there are so many fresh builds be­ing com­pleted around the coun­try. “Corguard is in­cred­i­bly sta­ble and does not break down and be­come acidic,” said Dil­ley, con­tin­u­ing, “This new syn­er­gis­tic anti-cor­ro­sion chem­istry not only pro­tects all the com­po­nents … it keeps engine com­po­nents look­ing and work­ing like new. When we re­moved ra­di­a­tors, wa­ter pumps, and heater cores from our high-main­te­nance fleet test ve­hi­cles, they look brand new.” Per­haps the age of bet­ter cool­ing is upon us?
