OK thanks Rumcajs
Would it be more the aircon thing as it sits in front of the Rad .
What ever I do it's going to be a PITA
Well it could be but in any case to get to A/C (Air Conditioning condenser) it is easier to remove radiator because you do need to back wash it. You'll be surprised how much stuff get trapped in the radiator even though you have all that stuff in front of it ( A/C condenser, PS cooler, etc.
That's why I'd rather make sure it is externally blocked by using a torch/source of light from behind and then have a assistant to look. You can see it shining through easily if the fins aren't blocked. As you move the light around your assistant should be able to see that movement from the front even through the condenser or any coolers you have there, indeed doing in the darker place is prefered.
I went to see on mine if it can be done and yes you can shove the light in there from bottom of the fan shroud quite easily. I left my LED workshop light inside the shroud, looked from the front and I can see the light, yay.
Its up to you really, if there is a lot of debris between the radiator and the condenser then go for it and remove the radiator if you suspect that.
Normally cooling systems problems like overheating are a guess work or process of elimination, start with the easiest first IMHO.

Just on a side note .
Is it possible to replace the fluid in the fan hub on my trol or do I have to
buy a new one ?

He has been doing it past few months testing the best amount of fluid to use for best results.

Just gets better n better
I'll give the rad a good flush first .
Are they hard to remove ? It's not like I've never done something like this B4,
it's just it all has to go back the right way
Hardest thing is to put coolant back in without causing an air lock as that will come back at with the vengeance. Of you are taking out then send it off to the radiator place and have it tested there for internal blockage as well. When was the last time you have changed coolant in it?

If you want to monitor and log ECU, I have a 2002 Elgrand with ZD30 (non CRD ) so has OBD2 plug but Consult protocol. Bought a bluetooth consult scanner with OBD adapter from buyobd http://www.buyobd.com/index.php?main...&products_id=2
Cost about $65 and took about a week to arrive. I use NDS1 on my 8 inch tablet which I have mounted above the dash. Run it it dash mode (when not using google maps) and display about 12 items continuously. Or switch to data mode and record a log to look back on later.
