I put Rislone head gasket fix which I found similar #sealer in #youtube video in my radiator and overflow tank and my Ford Festiva was drivable again after the old radiator cap would not go on when removed as replacement radiator was non-standard and I tried to drive to Supercheap Auto to get fitting radiator cap with no radiator cap (as it would not go on) when I should have caught public transport and not destroyed engine. #RACQ found radiator cap that fitted using a ruler. I got Rislone from Supercheap Auto in Morayfield via bus. Thermostat stuck due to or after the overheating so that had to be removed and later replaced. #fordfestiva #headgasket #overheating #headgasket #carrepairs #rislone #radiator #radiatorcap #publictransport #supercheapauto #caboolture #morayfield #engine #thermostat http://www.youtube.com/watch?v=q3_kDiQb7lE
