Thermostat issues
Hey guys, so when I got my 07 I noticed it never warmed up, but sitting in traffic itd creep up then drop when i got moving. This screamed thermostat to me so I got a new one, put it in with the spring side down, and I still have the same issue. The diagram of the cooling system states I put it in right, so is it possible I got a defective thermostat or am I missing something? Thanks in advance

You should be able to test it, using a pot of water on the stove, and a thermometer.
The primitive system in our 250s results in a fluctuating temperature. Some 250 owners like the Thermo-Bob system, which creates a bypass setup like cars have. But the stock system should allow the engine to warm up to the thermostat's set temperature. |

Does it overheat? Mine definitely fluctuates, but only gets fully hot when I'm really thrashing it. So long as the coolant doesn't boil out I just roll with it.

When you say it doesn't warm up what is the temp gauge showing? Ambient air takes in account of warm up temps as well
