I have a 94 cadi, sls and it overheats when it wants. It doesnt matter if I am stopped, on the freeway or climbing a mountain. Sometime it overheats really bad and sometimes it overheats a little and then goes back down or sometimes I have no problems at all. I have changed the thermostate twice, water pump, radiator fan, flushed radiator, block/pressure test, all done and it is currently in the shop and they have no idea what is causing it. They even ran it for 4 hours straight and could not get it to overheat. PLEASE HELP! Any ideas?
