Hello All,
New member with an ongoing problem. My 2006 Vibe 5sp overheats within two city blocks of driving. However, it can idle, and even have a sustained rpm of 2000-2500 while parked, and never go beyond normal operating temp. I have replaced the thermostat and radiator cap. When it overheats, it appears that all the coolant blows back into the reservoir, and out the overflow tube. I have ZERO engine codes. I have heat while in the driveway, although it takes quite a while to warm up, and of course no heat at all when it overheats. Radiator does not appear to be blocked. I haven't been driving it to avoid further damage, but I, and everyone else who has looked at it am stumped! Wouldn't a bad head gasket cause overheating at idle? Wouldn't the water pump leak if it was bad? No hosed are being sucked flat, and I have done what I hope was a completely thorough job of bleeding air from the system. The car has 109k miles on it, and was purchased with a prior salvage title due to a collision with a deer. Front end was repaired, and I have the service records from when they rebuilt the valves and head at 108k. Please, any help would be so very much appreciated!
