barnacle Posted February 26, 2023 Share Posted February 26, 2023 Does anyone know the coolant capacity for an 86 22RE dolphin I know the radiator is larger than the standard trucks. Quote Link to comment Share on other sites More sharing options...
linda s Posted February 26, 2023 Share Posted February 26, 2023 Not substantially larger. 2 row instead of one means more cooling capacity but not necessarily more capacity. 9 to 9.6 quarts but that would require draining every bit out including heater core. Not easy to do. So figure something around that. Make sure you run it a while with the cap off to get all the bubbles out. A tightly fitting funnel can be used to stop mess from overflow. After you see no more bubbles let it cool in place. Antifreeze level will go down so you can remove the funnel and top radiator off.
