ok guys, more advice needed for a mates scoob, its a 93 wrx import, its overheating when sitting idling, temp goes back down a bit when driving it, hes just had the thermostat done thinking that was the problem but its still overheating, top radiator hose is hot but the bottom hose stays cold, when u take the expansion bottle cap off after driving it the water in the expansion bottle is bubbling. and alot of steam coming from the car. any ideas on the problem? also the engine is rocking quite a bit in the engine bay, the garage he took it to says its cos its firing on three cylinders, would this be right? i thot it might just be the engine mounts, but garage said it wasnt.
