I need to replace the coolant expansion tank on my '05 roadster limited, 106k miles.
Also have a new thermostat to install and thought I should replace the water pump and once I'm into it that far might as well replace the serpentine belt, idler & tensioner.
And with all that removed and out of the way I might as well replace the alternator (battery too).
My question is am I missing something?
Is there a coolant temp sensor or anything else in the glycol system?
Thank you!
