Hello, I've had a head replacement and overhaul done on my 300SD due to a cracked head. Before, it ran with the temp needle slightly above the 80 mark. Now it runs maybe a quarter inch higher (see pic). I've changed the thermostat twice (once with a Stant brand, then with Mahle). I've also replaced the sending unit. Is this reading normal? If not, what's next to try? Reads this way regardless whether highway or city driving.
