Q: Car won't start after replacing the radiator it's a 2008 grand jeep cherokee laredo with a 3.7 engine

You've only got 40,000 miles on it and it's 2005--it's old. So, I'd say change the fluid and filter and use the factory fluid. Because the most common problem on those cars are bad transmissions, you don't want to chance...
