4ja1 is base engine sa isuzu crosswind from hi-lander box type to sportivo. ang fuego is 4jb1 correct me if im wrong.. yes mo dagan bisan walay tubig! i can attest to that bec. my cuzins xuv happend to have a broken radiator and he was cruising at recla.. dd2 ra sya ka bantay pag pa tubil nya sa shell na uyog na kaau ang engine den mao diay to overheat and wala nay tubig but still its still running and after the horror the engine still in its perfect running condition.
not all isuzu engines are durable, in fact the trooper's 4jx1 is the most vulnerable diesel engine i can remember and its very high maintenance plus its a lemon hehe.
