Did GM make different versions of the lower intake manifold for their 1999 Chevy Venture with a 3.4L V6 engine? I have recently bought a used intake lower intake manifold and found out slight differences between the old and the new used version. The main difference is the thermostat housing. On my part there is a coolant temp sensor port. The new used is missing the port. Did GM switch to a different design on these parts? Thanks, Jay
have the same problem?
