Sprint Radiator

Q: Sprint Radiator

What is the correct radiator for a Sprint engine? I am worried I do not have the correct one since I keep over heating plus someone mentioned my Sprint is missing “Filler Panels.”

A: Single core is correct for a 1968 Sprint, unless it had the HD cooling. Radiator should have a metal tag with the letters “ZA”. Code for the HD unit is “UF”. A 3 core from a 350 V-8 will fit right in the same location.However the finger guard may not. OHC-6s dont use a fan shroud. I think the radiator you have is clogged or in poor condition. I’ve never had an overheating problem with any OHC-6s.

A: The Filler Panels are the panels that go between the core support and the front bumper support.

They were installed in 400 cars and A/C equipped cars. The idea was to force as much air as possible through the radiator, instead of having it “leak” out around the bumper. They can be bought as repros, if you’re interested in using them.
