The bastard got hot on me going up the freeway outta Adelaide Saturday. Not as bad as last time. It got to 109C. The only thing not replaced was the water pump. Is there any tell tale like a drip or anyway to test the bastard before I replace it? Thermostat has already been replaced. Recon radiator done. Viscous hub has been serviced. What else could it be? Has been fine up till Saturday
