Matt replaced my radiator with a new oem one. At the last event it didn't overheat until I was doing figure 8s on the side lot. I noticed it running hot then parked it. When I was going home, it went up to H again, I turned on the heater full blast, after 10 minutes or so the temp went back down, I turned on the AC and it was fine.
So my battery died and tonight i finally had the chance to jump it, FOERST time driving it since the event. less than a mile down the road it started running hot again. I turned on the heat full blast, but the air wasn't hot coming out of the vents.
Drove it home and was going to put water in it, but it was pretty much full. I squeezed the top hose, it bubbled a little. I put a little water in, squeezed the hose untill the few bubbles stopped.
