My 180 challenger with a 215hp 4tec would always run at 186-88F unless wot where it would reach around 190-92. Recently at 6k Rpms the temp is now around 190-192 and at wot around 200-205. Is this normal. I have already flushed the antifreeze and added the Seadoo brp premixed and am currently running 60/40 since I'm in fl and the temperature never gets below 20. Could my thermostat be bad and if so how difficult is it to change?
Thanks
Sam
