So I am wondering if either side of the coolant [ in , out ] can be blocked off - will the engine cool with out issue by blocking off ?
Going to be removing intake & exhaust manifolds to repair a exhaust manifold leak - so considering eleminating the EGR cooler ?
Maybe a link to a cooling system diagram ?
Thanks
