How to stop overheating ?

[diff-breaker]

Bit of perhaps a daft questions but I will ask anyway !
How does anyone stop engine overheating after a land rover show or pay/play of mud in the radiator - other than jetting it out ?
Yes you guessed it - it overheated on way back home this last weekend and head gasket has gone ! :oops:

short of a new radiator... all you can do is jet wash the rad out after playing.

but that doesnt help you get home afterwards!!

with the rad having 3 rows of fins on the cores, the inner layer seem to corrode quicker than the outer layers.

hence the heat is not disapated as efficiently, ergoe, overheating.

i had the same problem for a while, a slight incline on the motorway and i was getting rather warm.

a new radiator has solved the problem, 100%.

hope this helps.

 mine done that last weekend .  . but mines new water pump as well as thats shot . . . but need a new rad aswell as its leaking . . . to stop over heating and blocked rad i cant think of anything just jet it down after a event ????

Untill I get home for jet wash, I always run my heaters on full blast to the floor! :)

this usually stops the temp rising enough to worry, it can rise from 1 third to half way on big long hills but soon settles, and this is when my rad looks like a big block of mud!! Lol

wet mud still disapates the heat fairly efficiently,

but as soon as the mud dries out it becomes a brilliant insulator and stops the cooling.

what about one of these radiator covers?

or make your own out of a bit of tarpaulin and gaffa tape? then just whip it off when youre done and voila! no mud in your rad.
