What engine mate?

it is a 1.6 carb from a mk2 golf EZ engine code

Could be an airlock. When you started the car was your heater in the hot position? Is there any hot air coming through?

ye it was on the hot postion but there was no hot air which was worring

Back flush radiator and heater matrix with coolant flusher , check electric fan cuts in .

ye the fan kicks into at 1st but after 10mins it didnt seem like it

My mk1 cab ran hot, turned out the engine breather, part of the rocker cover, was totally block so the engine had loads crank case pressure! i cleaned it out(soaked whole cover in engine degreaser for about 4 hours) and she sweet now!!

ye i have a little filter on the end of it, i will give it a clean 2moro

I'd go with Chudd and backflush it. Pull both heater hoses off and connect a garden hose to the outlet and run until clear. Then do the same to the block.  :wink:

hey guys, i flushed the heater matrix and all good but i have replaced the 2 valves leading to and from the heater matrix, the look like pressure valves that let the water into the matrix. it seems to be ok for now, still gets hot quick though
 
but no overheating as of yet

hey guys, on my way to work yesterday, my car overheated again!!!!!!!! omg, i dnt no wat is left to try!!!

there is nothing left for me to change is there?

Rob

does the whole radiator get hot? i mean is there any cold spots on the radiator when its running and up to temp? ive had many rads partially blocked and will be fine whilst ticking over,but when driven cant remove heat quick enough and will then overheat the engine,may be time for a new radiator.

there is anew rad in there, brought 1 still didnt make any difference, i took the thermostat out and it doesnt over heat now, so maybe a faulty thermostat
