went to napa to purchase test strips. they had none and all they can order is a bottle of fifty. in the past i have bought fleetguard strips and they have an expiration date. do the napa strips have an expiration date, and is there another place where i can buy a smaller package? although paying eighteen dollars for fifty is better than purchasing a motor.
Here at the John Deere dealership where I work, we have "3-way Heavy Duty Coolant Test Kits". They measure freezepoint, Molybdate, and Nitrite. On the back of the package, they state "Measures liner pitting protection(SCA level), no matter what brand of SCA is used". Contact a nearby John Deere dealer, Deere part Number is TY16175. Our list price is $4.35 for four test strips.
