Morning all,
Still having slight issues with my Sierra. Started getting hot a bout 8 months ago-replaced water pump, thermostat and foolishly (I think) the HG. On the level the car is fine but when you come to a hill the temp starts to rise-it doesn't overheat but climbs rapidly towrds the Red.
I'm now suspecting a partially blocked radiator-I tried flushing a few months back and it did make a slight difference. The radiator is original and 20 years old.
Any ideas greatly appreciated./
Steve

could be the radiator try the holts 2 part flush its worked for me but somr peeps on here may have a better solution
-
take radiator out and stick hose in it and flush it through while rad is placed side ways/upside down -works on rover p6 rads :y
you can blank other outlet on rad with plastic bag/hose clip if required
-
Thanks,
Tried the 2 part flush-will take it out.
The radiator on my P6 was very easy to take out if I remember!
Wish I still had it (P6 3500S).
Thanks

just stick your mitt on the rad when the engine is hot,it should be warm at the bottom and stinking hot at the top.you will NEVER successfully flush a parallel flow rad that has furred up inside.water gives up its limescale at approx 60c, engines run at approx 95c.

Go to plumcentre/screwfix and get some fernox flush. Top stuff. :y
-
to be fair using a fernox etc could make matters worse,personally if it is orginal,get it refurbed or replacement,will be quickest and easiest option :y
-
Thanks all,
Will get a new one.
Cheers

Some of that stuff eats aluminium as well as limescale ;)

I used that on a 20 year old combi-boiler once thinking it would improve the performance. Not long after the heat exchanger failed and I had to buy a new boiler.... ::) :'(
