Welcome! And nice looking wagon! Welcome to the Pinto community, you will find a great group of people here that love Pinto's and are willing to help out. For oil use 10w-40 and a Motorcraft FL-1A filter. For the radiator l would check Rock Auto, they still have lots of Pinto parts at a reasonable price. Also check e-Bay, lots of stuff there and a lot of NOS parts but they can be a bit pricey. There are lots of places that sell carpet, e-bay and Amazon are your friends! Now here's a question, Pinto people help me out here. Does he need a zinc additive? Zinc has been removed from oil including diesel oil. When l had the 2.0 in the Pintoracer l used a racing oil that had zinc because of the cam riding on the rockers. Even though the 2.3 has hydraulic lifters the cam still rides on the rockers.
