Clean radiator

[donandmax]

Is it possible to clean the radiator on a 460 gas Damon Intruder. Iam going to try to clean it from behind to flush out dirt and bugs but dont see how to get to it, A lot of stuff is in the way. What method do you use ?

Pressure washing a condenser/radiator is not necessarily a good idea (it can bend the fins) and in your case access is limited. There are a couple of possibilities. I am assuming it is largely just full of dessicated bugs and dirt and you try the easy stuff first and work your way up.
Soap and water first (soak it first in cleaner for a while) and gentile water spray, use a soft brush. In an extreme case obtain some AC condenser/radiator fin cleaner, this stuff foams up and cleans really well. It is NOT an acid and the ones I am familiar with are biodegradable.

We bought our Challenger 378 used with 14,000 miles. I cleaned the radiator the best I could with a soft brush. Then purchased aluminum window screen I cut and attached it to all 4 front grills on the inside with stainless wire. Now all bugs get stopped by screen and it should slow any stones from getting to the radiator. It took me about 1.5 hrs to do the job and I think it helps with the look of the front of the MH.

just use a regular garden hose at low pressure You can spray the radiator first with soap and let it sit then hit with hose. As shadow said you can buy cleaner at an auto parts store if necessary but usually the soap and water are enough

Love the screen idea. I think I'll try that myself. Also you might try a HVAC store. They make a product that can be sprayed into aluminum condensers, without harm, which eats up organic material.
