All removing the thermostat does is change when the overheating problem occurs. In my opinion, it's never a useful option.Do you think to get me by until the new one comes I could pull the thermostat to help it flow more through, or would that just make the problem worse from moving coolant too quickly through the engine, not so much the radiator?
Yes, though there was a picture looking through the cap opening and it was still scaled up.Didnt the OP say a rad shop cleaned the rad and said it was in good shape?
You know, the 400 may have been a 2 core? It's been years since I had one. But as soon as it started to scale up, the car wanted to run hot. I wondered if the HP 400 got a better radiator than the regular 400.I think I would find a different radiator shop.
Heck a 318 needs a 2 row unit.
