I recently installed a five speed box and EA82 into an 83 brumby. Not the smartest thing I have ever done not much space and seems to drink like a thirsty hippo. However I have had constant overheating probs since it went in. so things I know:-
not the heads (just re-done)
not the rad just been flushed.
replaced heat sensor.
replaced thermostat gets hot with and without.
I am begining to think an 83 Brumby maybe does not have enough radiator to cool an EA82 block can anyone help. I read somwhere hear about a double core rad but when I spoke to the local rad guy about this he laughed at me and said It would already have one. I am gonner have to get ride of it if I cant keep it cool. Genrally heats up over 30-40ks in the hills I live in Albury if that helps

none of my L series radiators are double core - food for thought

did you drive this engine in its L before and no overheating ?

Not the engine itself causing this ?

otherwise try the L rad if u can get one

I have been fiddling with an L rad to go into a Brumby. it will go. the bottom corners of the rad touch the body so a ball hammer fixed that. u need to reverse the mounting system underneath to accept and secure the L rad

If it's going through fuel and overheating check your timing, these are both signs of retarded timing.

I would also check your water pump, even though the outside may look fine the impellor could be stuffed.

These 2 would be where I would start as they are the simplest and easiest to check, and cost next to nothing, after that I would see if you can borrow a known good EA81 radiator or have your current one rodded, a flush usually won't fix a badly clogged radiator.

Thanks for the advice will try the time first the water pump is new so it better bloody work. I dont have a prior history so I cant answer the question. Will try the roding and find out about dual core rads. Cheers
