The Zerex story
What Valvoline actually puts in your radiator
Valvoline owns the Zerex brand, which is one of the larger coolant lines in the US aftermarket. The Zerex product family covers Original Green (IAT, for pre-2000 vehicles), Dex-Cool (OAT orange, for GM), G05 (HOAT yellow, for Ford, Chrysler, VW/Audi pre-2008), G40 (silicate-stabilised OAT for newer VW/Audi), Asian Vehicle Pink (PHOAT for Toyota), Asian Vehicle Blue (PHOAT for Honda and Subaru), and a universal long-life ready-to-use formulation.
The bottom line is that for almost any 2010-or-later mainstream vehicle, Valvoline can install a Zerex product that meets the OEM specification. The Zerex Asian Vehicle Pink is formulated to meet the Toyota Long Life Coolant specification, and the Asian Vehicle Blue is formulated for the Honda Type 2 specification. Independent lab testing publicly cited by Valvoline shows the Zerex formulations meet ASTM D3306 plus the OEM-specific tests.
The exception remains BMW, Mercedes, Porsche, and a few Volvo and Saab specs. The G48 specification used by BMW and some Mercedes models is closer to G40 territory but requires careful matching. A Valvoline location will sometimes have the right product, sometimes not. Ask the location to verify against your owner's manual specification before booking.

Watch-outs
Three things to confirm before you drive in
1
Confirm the coolant spec
Look up your vehicle's coolant requirement in the owner's manual (or on our coolant-types guide) before you go. Tell the technician the exact spec you need. A mismatched fill is rare but it does happen.
2
Decline upsells you do not need
Valvoline locations sometimes recommend a fuel-system service or air-filter swap at the same visit. Both can be legitimate, but their value depends on actual condition. Ask to see the air filter and the fuel-system test result before agreeing.
3
Check the app for coupons
The Valvoline app routinely runs $15 to $25 off coolant flush, especially when combined with an oil change. A 60-second app check before driving in is the easiest way to land in the $90 to $100 range for the entry-tier service.
Common questions
Valvoline coolant flush FAQ
How much does Valvoline charge for a coolant flush?
+
Valvoline Instant Oil Change charges $99 to $139 for a Premium Radiator Service in 2026. The entry tier is around $99 to $109 for a standard exchange with universal coolant. The premium tier with Asian PHOAT or HOAT coolant runs $119 to $139. Coupons of 10 to 20 percent off are frequently available in the Valvoline app.
What is included in the Valvoline Premium Radiator Service?
+
The service drains the existing coolant and replaces it with new Valvoline-branded coolant matching the vehicle's specification. It includes a visual check of hoses, the radiator cap, and the reservoir. Most locations perform a powered exchange rather than a gravity drain-and-fill, which replaces around 85 to 95 percent of the old coolant.
Do you have to leave your car at Valvoline?
+
No. The defining Valvoline Instant Oil Change experience is the stay-in-car bay. You drive in, stay in the driver's seat, and the service is performed around you. The whole appointment including a coolant flush typically takes 25 to 40 minutes.
Does Valvoline use Valvoline-brand coolant?
+
Yes. Valvoline Instant Oil Change stocks the Valvoline branded Zerex coolant line, which covers IAT, OAT, HOAT, Asian PHOAT (pink and blue formulations), and a European-spec G05 yellow. For most mainstream vehicles the Zerex line meets or exceeds the OEM specification.
Are Valvoline coupons real?
+
Yes. The Valvoline app pushes 10 to 25 percent off promotions for individual services routinely, especially around the spring and fall maintenance seasons. A coolant flush coupon of $20 off can bring the entry tier under $90 if combined with a routine oil change.
Is Valvoline faster than Jiffy Lube for a coolant flush?
+
Usually yes. The stay-in-car model means no waiting room queue. A typical Valvoline coolant flush plus oil change is about 25 to 40 minutes including the wait time. Jiffy Lube's comparable Signature Service Radiator Flush runs 30 to 60 minutes with queue.
Is Valvoline good for European cars?
+
Acceptable for VW and Audi where Zerex G05 yellow is the spec. For BMW, Mercedes, and Porsche which require G48 or 325.0 spec coolant, Valvoline may not stock the exact formulation. Confirm in advance or use a European specialist or the dealer.
