NL 2.8 cracked radiator tank

[2800ITDNM]

So the mates NL 2.8 (160000km) came home on a trailer last night. Been using a small amount of water over the LWE (say less than a litre). No sign of water in the oil, oil in the coolent etc, running well etc. Towing up the Freeway the temp gauge shot up, steam coming from the intercooler and a top tank split. Anyone got any thoughts about what went wrong? (besides the obvious). Is the thermostat or radiator cap or other component the suspect? Something to do next weekend it seems!

mine has just done the same. i think shock has cracked the rad as the thermostat is fine. the tank housing is just made of paxolyn/plastic. The ruber bushes on the rad mounting have perished. did you sort it

My mates blew a head gasket, pressurizing the radiator tank and cracking it. Expensive weekend all up. Hope yours isnt so dramatic.
