Does 1999 Isuzu rodeo have an interference engine. Is it true they have to first replace the timing belt and water pump before determining whether the engine needs to be replaced?

NO the rodeo does not have an interference engine. You can break the timing belt and not ruin the engine.......... THIS IS AN INTERFERENCE ENGINE. IF THE CRANKSHAFT MOVES WHILE THE TIMING BELT IS OFF OR BREAKS, THE VALVES WILL COME INTO CONTACT WITH THE PISTONS.
