Just on way home after a weekend away with new twin axel caravan and the rad blew on p38. (2000 DHSE auto)

Ordered a bearmach one. They offered a britpart but I refused that.. Are bearmach ones ok?

It over heated while towing van home last week only the once and cooled straight down again been fine since now it over heated and popped rad. Never any problem when not towing

Is te rad the probable cause?

Thanks

could be the thermostat not opening correctly,hanging up,sticky and did you check coolant level and a good mix on you coolant..... 50/50 mix good for -30f

Stupid plastic radiator tops are prone to blowing when they are getting old and under load while climbing steep hills or caravan towing.
I had one blow in Kazakhstan and found a guy that made up a top for my radiator with a sheet of alumininum and its still on the car now.
