coolant bypass pipe. timing cover to intake manifold, passenger side.
This is that silly beast that corrodes over time (usually under the hose ends) and gives you the mysterious coolant leak. Or worse, the leak that was going on while you were driving and you only noticed when you saw the temp gauge rising.
These usually start corroding under the bypass hose connection (right where the clamps are) and since it is the intake manifold AND throttle body lines that connect to it, you get the double dose of corrosion fun. If you are carb’d, it’s just a single hose, so, slightly less to go south.
The gasket for this is actually part of your intake gasket. Yeah, it’s never easy, is it? So if you are replacing it with the timing cover still on, let me know and I’ll send you a sacrificial paper timing cover gasket that you can cut out the soot for it and LIGHTLY silicone in place. If you are doing this pipe the same time as the timing kit, use the factory timing cover gaskets and you are golden.
fits 1984-1989 22R carbureted
Fits 1986-1995 22RE / 22RTE
For 1984-1985 22RE you’ll need the “update kit” shown in the dropdown menu, your configuration of pipe and bypass hose have been discontinued so you’ll need to update the whole shebang (pipe, bypass hose, clamps and intake manifold elbow) as shown in the pics.
