    Default Drove through a flood, how do I clean the rad now?

    On the way home from work, the rain was torrential with flooding.
    I had no choice but drive through a flood, very carefully, there were a few cars drowned and smoking (Steaming) at the side of the road, I just crawled through whilst allowing the clutch to slip a little and keeping the revs up a bit.

    Now my rads are full of leaves and mud and faeces (Oh yes it smells!). The engine temperature is about 10 to 12 deg hotter than standard.

    I tried a high powered hose through the open grill but it will not shift the blockages.

    Any ideas anyone?.

    The car is a 150 CDTi facelift so only the bottom section of the front grille is open, and this was under water!!!.

    Stop it with the Pressure hose mate. That will only make it worse. Pressure washers can easily bend all the fins, there was a thread ages ago about this very thing. I'd let it dry out and doing this will naturally shrink any debris, then blow it out with an air line.

    That's aright, I didn't use a jet wash, just the normal garden hose with the nozzle adjusted to jet.

    I'll check it again in the morning after it's had time to dry.

    Thanks.

    Now, where do I get an air line, do you reckon vacuum cleaner might do it?

    Try the tyre airline at a garage forecourt.
    Gently bentley with your radiator whatever method you use to clean it.

    You could try soaking the crud out. Instead of a pressure hose, just a normal one running at low pressure and slowly dissolve the mud.

    The leaves will eventually dry out and rot away.

    whatever you do, Dont use compressed air or high pressure water !!!

    Soaking in water is the only way to "Safely" unblock you're radiator.
    Best bet, If you can is to remove the radiator and leave it soaking over night.
