I'd try and chase it out with compressed air or a leaf blower. If it's small enough to enter the grill, it's small enough to exit it.

 

The pocket between the front grill and radiator is slowly accumulating debris. Is there a way to easily access this area to clean it out?

I have been using an air compressor to blow leaves out. I look forward to an easier way !!

 

I have a set of micro vacuum attachments that would work:

Funny, glad someone else noticed! I posted about this back when the leaves started to fall - there’s no easy way in without some disassembly. But you can try the vacuum attachments or a parts picker which someone recommended to me…

Cleaning behind the grille

Has anyone figured an easy way to clean the leaves out from behind the lower grille? It seems to be entirely shrouded in plastic and foam from under the hood. But I figure there’s other OCD folks out there smarter than I am! Thanks :)

I wouldn’t use air blowing in … it’ll likely just push the stuff into the radiator, right? I do like that vacuum thing @SunWizard mentioned though…

 

Small size wire and something sticky on the end will work wonders... that is my hand made tool for this problem....blowing dust out is ok but blowing big debris in are not something i would do.

 

Long tweezers?

 

My shop vac has a long narrow attachment like the one pictured. It's great for tight places.

 

These grilles are always tricky to clear of debris. Shopvac, leaf blower, and lastly long nose angled pliers are my tools of the trade. On my TT I would also drop the belly pan annually to reach in from behind but not a solution for our ID.

 

I suppose you could drop the belly pan more easily than removing the bumper but it will be hard to find the oil drain plug

 

Easy and cheap solution. Get the necessary materials from the hardware stores.

 

Here is my before picture.

 

I think a shop vac would be a good tool to use for cleaning the radiator. Using the crevice tool attachment can help you reach all the nooks and crannies to get it really clean.

 

Where's the after picture?

 

Here's the adapter based on your design, using 1" OD tubing from hardware store.

 

Problem is there is a thin plastic grid that I suppose is meant to protect the radiator fins, but it also traps bugs and leaves. After picture:

 

Also this is the status after about 15,000 miles of highway driving. At some point I will have to get one of those fin combs and straighten them out. Already probably 5% obscured airflow.

 

Here is Special Tool #2:

After poking and picking at each bug and leaf, I got almost everything out. These are Mississippi bugs from our trip last fall, which means they have been in the dry Colorado air for six months now. It took 15 minutes on my knees to do this; there is zero chance of a repair tech doing it. There must be an easier way.

I'll spray it with the hose tomorrow and that should clear out the remaining debris. But are there no places in Europe where there are bugs in the summer???

You could try installing some sort of screen a the very front opening (like https://www.aliexpress.us/item/3256804167913352.html ). However, I think installation in a clean way is not possible without taking the bumper off and it still would be annoying to clean, though you'd have far fewer bent fins for a different air restriction.

 

I used long surgical forceps to remove a couple of leaves, twigs and pebbles.
After grabbing the first piece of debris or two I get a good handle on the technique and it made quick work.

 

Seriously though, how much disassembly required to reach the front of this heat exchanger? I appreciate the rock guard but it’s keeping a blanket of bugs over the lower 1/3 of the heat exchanger. I don’t think there’s enough time in the day to keep this clean with tweezers and a 1/2in diameter vacuum tube. I do have a full time job.
This picture shows 3.5 months of accumulated insect carnage from rural/agricultural Oklahoma. I’m prepared to get flamed for letting it get this bad but I’ve been staying at my folks’ farmhouse without access to any of my tools. In a couple months we’ll be moved into a house and have all my normal car care stuff.
I know this is making the cooling system work harder than it needs to, it’s 104-degrees outside at the moment.

 

If you have time to spare.
On weekends, you can use mesh type of screen. But it will take removal of front plastic bumper.
Or you can do from the outside but will not look pretty.

 

I’m not opposed to using zip-ties and window screen in front of the grille during heavy bug season, but I’m trying to decide which is worse for airflow, a mesh screen over the entire intake, or the lower 1/3 of the heat exchanger being roughly 50% blocked with bugs. If that external mesh gets blocked it affects the entire heat exchanger(s). It’s a shame the belly panel below isn’t easily removed - I’m tempted to make modifications to make it so.
I’m SO glad I did the ceramic coating before moving here, some of these mutant grasshoppers leave a 4-in diameter splat when they’re hit. 🤮

You can salvage radiator screen from Big Semi Truck latest generations. They are sturdy enough ,and they will not create air flow drop. In worst case scenario there is still electric fan that can activate if additional air flow is required ( worst case scenario).
New Western Star trucks that i have seen have great screens for this project.

 

Every late Fall I had to drop the belly pan on my TTS to clean out front end lodged leafs, etc. It was the only way to get at some of the more stubborn debris as no amount of front needle nose pliers or water/air flush would work. Even then tedious to reach a couple areas.

But then we enthusiasts go where others fear to tread.

I did a search but didn’t find this, thanks. Looks like a good project when it cools down this fall.

 

I have installed radiator/intercooler/oil cooler rock chip protection screens on a number of low slung vehicles that were especially susceptible to same. Relatively low cost and worthwhile DIY.
