I have a 2009 with just below 6k on it and I noticed that my temp gauge was starting to run a little hot. Not pegged but about ½ an inch higher than normal. The engine is running fine. Good throttle response,idle, etc. So anyway after closer observation I noticed that my radiator was plugged. Not internally but externally where the air flows through the grill and the cooling extrusions. Where 99% of my travels consist of old New England roads that have needed repaving for the last 20 years and some groomed state forest roads I am speculating that the majority of the crud is bug guts and air born vegetation. I gently scraped a lot of it off but it appears that there is still a lot of debris in the cooling extrusions. I am looking for suggestions of products that might help with my desire to get the air flowing correctly again. Ideally I would like a spray on hose off product. But I am open to all suggestions. I noticed after searching the forum that some have been proactive and installed filtering material across the grill which would appear to catch all of that crap prior to winding up like I have. I am presently pursuing that option. Any suggestions of material and a harmless means of fastening it would be greatly appreciated also. Thanks in advance for all suggestions.
