    T1N - Cracked Head Leaking Coolant

    Hey guys, Back in June I purchased a 2005 3500 Sprinter with 190k miles and I have had to take in to the shop 2 times since then for repairs to the engine. The first time was because of a hole in the valve cover that the previous owner repaired with JB Weld and an aluminum pop can. It's a long...

    Radiator reservoir leak and delaying the inevitable

    Hey all, hoping for a bit of mechanical wisdom. I have a 2002 with 250k miles on it. I’m pretty sure the reservoir has been leaking the whole time I’ve owned it, but has possibly gotten worse over time. I tried to patch with JB putty, but like others around here, the leak persisted. The leak...
