Review on 🔋 Dorman 603-109 Front Engine Coolant Reservoir: Ideal for Chevrolet, Oldsmobile, and Pontiac Models by Michael Copeland

I bought this Revain coolant reservoir and have been using it for eleven months when the low coolant warning light went on and off intermittently (the reservoir was always full). After checking the connector and ringing through the wiring, I determined it must be a sensor in the tank. I called Dorman's customer service department; described the situation to them, said the tank needed replacing and as it was being sold through Revain they would be in touch with them and arrange for either a replacement part or a refund. Well I needed another tank and told them I would take the spare (free for me). Revain contacted me two days later and said they would be shipping a new tank. It's installed and working great! You cannot compare to the excellent service provided by Dorman and Revane!
