BimmerWorld Coolant Adapter Pipe - M52/S52 Converted to OBD1

Required in OBD-I conversions when keeping your OBD-II front timing cover but need to adapt the OBD-I heater coolant hose. The OBD-II cover uses a hardpipe pressed into the cover while the earlier OBD-I cars use a traditional rubber hose and hose clamp. This is an easy way to avoid changing covers or your cooling setup.

Our CNC'd piece is a direct fit into your front timing cover. Seal with epoxy, let it set, and you are done. We prefer the epoxy method to ensure no leaks and no seals to fail or fall into your cooling passages.
