ok. the old motor was replaced with a rebuilt 4.2 liter, year unknown. this engine was rebuilt years ago, by an unknown shop. (i know...bad idea. was the only one we could find). replaced water pump, thermostat, and radiator. around town, runs fine. i took it out on the open road, and, presto! overheat city...to the point that the plastic (i know...another bad thing) radiator blew to kingdom come. towed back to the shop, replace thermostat, nd, radiator, and, she purrs like a kitten. idles smooth, behaves fine.
is there anything particularly quirky about 4.2 engines i need to know? this jeep was only doing 52 when all hell broke loose. i'm sort of scratching my head, and, so is my mechanic.
