Hybrid_From_Hell Posted October 14, 2013 Share Posted October 14, 2013 In a vain attempt to try to keep my rad core clear of extreme debris (when I last did some deep wading I ended up with a rad full of watery bind weed !) I have a plan, but part of that includes a fine mesh mounted somehow on the rear of the 90 slatted grill So, I am after about as fine a mesh as possible that will have the least effect on air flow Any ideas what and where from please ??Nige Quote Link to comment Share on other sites More sharing options...

David Sparkes Posted October 14, 2013 Share Posted October 14, 2013 I am after about as fine a mesh as possible that will have the least effect on air flow. Nige Conflicting demands, I feel. It's effect on airflow will be noticeable, but not perhaps sufficiently to be noticeable while everything is clean, but what if you went into the 'watery bindweed' with the mesh in place? Remember the original chaff guard was there to deal with just that - DRY chaff, not lengths of wet bindweed, or liquid mud. The mesh will clog up with the weed, or liquid mud, and even if there is space between the grill and the radiator, try running the vehicle with the grill blanked off to see how cooling is effected. How will you clear the fine grill of obstructing weed / mud? Is it the speed of competition that stops you following the tried and tested practice of stopping to drape a fertiliser sack over the outside of the grill, removing it when the 'water' has been waded through? If you really insist on a solution that involves you keeping your backside in the seat, I can only suggest fitting an electric fan in front of the radiator, but making a 'blade assembly' that incorporates draught excluding brushes having the tips wiping over the face of the radiator. The brushes may not stop the weed / mud collecting, but would (should) wear away the weed / liquid mud that collects. You could use a fine mesh in front of the radiator as the collection point / wearing surface that interfaces with the brushes. This would stop the gills in the radiator being folded over by the brushes. If you can keep the blades AND the brushes in the 'blade assembly' you might also benefit from an increased airflow, counteracting the restriction caused by any additional fine mesh. HTH PS. I see you have ~£230 with which to implement my idea, if you don't use an original chaff guard :-) (It would be too small anyway, as it's made for narrow Series radiators (45 x 87cm)). Correction. Having found the same item on ebay I see it is designed for the Defender, and can be bought via ebay for 'only' £90 (free P&P). Quote Link to comment Share on other sites More sharing options...

CwazyWabbit Posted October 14, 2013 Share Posted October 14, 2013 At that price Nige you want to get out of doing diffs and start making chaff guards, obviously that is where the money is Quote Link to comment Share on other sites More sharing options...
Tanuki Posted October 14, 2013 Share Posted October 14, 2013 Have a look here: http://www.expandedmetalcompany.co.uk/metal_laths.html Whatever you do, I'd suggest fitting the screen to some sort of frame and make it easy to remove for cleaning. You _will_ get stuff going through the mesh-holes and getting stuck. It's far easier to take the screen out when it clogs than try to clean it in-situ.

V8 Freak Posted October 14, 2013 Share Posted October 14, 2013 Nige.... Just leave the truck in the garage for another year...

muddy Posted October 14, 2013 Share Posted October 14, 2013 Take a trip to the nearest agri or plant workshops, nearly all heavy equipment run mesh screens to catch straw etc. What about making a grill with hinged slats you can close when wading? Will. Quote Link to comment Share on other sites More sharing options...
mike4444244 Posted October 15, 2013 Share Posted October 15, 2013 that's not a bad idea, you could make it look like a stock defender grille but move a lever and the slats hinge flat for wading http://www.google.com/patents/EP1531230A1?cl=en kind of like that?

TheRecklessEngineer Posted October 15, 2013 Share Posted October 15, 2013 If you're looking for a solution to the problem of debris in the radiator, then putting protection in front of it is a 'fix-it' solution. It doesn't tackle the root cause - namely that the filth and the radiator are in the same place. A proper solution would be to move your radiator. Or some kind of free-flowing filter arrangement - something like a cyclonic filter to provide free flowing air to the radiator, but that's a little overcomplicated.

Team Idris Posted October 15, 2013 Share Posted October 15, 2013 "Very fine mesh"; Mesh only needs to have holes slightly smaller than the gaps in the radiators fins, if that helps any If you want to stop weeds they could be much bigger mesh holes? (3mm?). Moving the rad is the only fix I've seen work Quote Link to comment Share on other sites More sharing options...
mickeyw Posted October 15, 2013 Share Posted October 15, 2013 I saw someone using scaffold safety mesh once, hung across the front of the std grille. It catches the muck and clogs up, so you take it off, shake the mud out and refit. It's a flexible mesh possibly nylon, oh and green when it's clean.
