    Well, the best way is to remove radiator and then pressure clean it backwards, just make make sure the nozzle is sufficient distance and at right angle to the unit otherwise the damage may occur.

    Also invest in some bug screen attachment on the front grille.....

    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.

    You may find the bottom section of your radiator is clogged with dust and
    sludge from everyday driving let alone off roading. My radiator was U/S at 200K
    04 ST 3lt auto, not enough Mods to keep me happy, but getting there

    I seem to recall that someone has done it by using Yotas spare parts viscous coupling fluid, apparently 2 bottles I just can't remember the thread but because the fan hub and coolant pump are not separable you'll have remove it.

    Its a messy job too.

    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.
