Fit like a glove on my 2002 Camaro Z28. Held up well. Would buy again.

I’m putting a GenV LT in a 37 PU. Took me a minute to install

The fit was perfect. Needs to come with standard clamps. The factory spring clamps are hard to work with on the road.

clamps are cheap but hose seals nice and tight sizing is correct one. works for engine stand runs or just heater core delete on ls engines
