Yes. Reclean radiator. Uv got mud and debri between the cooling fins for sure. If u mud a lot, carry a large piece of cardboard and bungy to front of ur grill as u go thru and take it right off after submersion. An old trick, but a good one.
I would seperate rads (trans/eng) enough to clean between carefully.
Keep up the fun!
