He shoots, he scores... score is 'clean rad' 1, 'expensive upgrades' 0...

'way to go, Yikes. The Alberta guys rock! (Was in to see the Stampede today; got stuck in traffic on MacLeod Tr for an hour... if my rad was dirty, I would have overheated with the AC on, just sitting there.)

Let us know what happens with your trailer, now. Change your thermostat while it's apart (I prefer the genuine ACDelco one - get it at a dealer.) and check your fan clutch - make sure it's clean, and make sure it isn't leaking the magic silicone fluid from the centre of teh coil at the front.

If it still overheats, change your fan clutch next.

Jim

Great pics, It's hard to stress enough when guys are haveing over heating problems that they need to clean the rad. The poster usally says, "it looks clean". Hopefully these pictures will help make believers out of "it looks clean" crowd so it won't take so much persausion for them to pull the rad.

Yikes!
Mine looks clean, but methinks I need to clean it anyway. Driving from Fairbanks AK to Valdosta GA next month with a ton of crap in the bed, I don't need to screw around.

I have never seen so much crap in a radiator. Mine didn't have 1/10 that much gunk in it last time I looked. I'm still going to pull it because it's never been done, but good lord, get a bug screen or something.

Mine was worse than that. The crap just accumulates - and lots of it goes through the coolers but not through the rad, so you get that 'wool blanket' effect in between them, like you see in Yikes' picture #1.

That fuzzy stuff is dandelion fluff, cottonwood tree fluff, dust, etc. It's real fine, but it adds up.

What's worse is the sand that you can't see in pics (hardly by eye) but it comes out when you soak and wash a few times. A couple grains of sand in each of the fins can cut your airflow in half pretty quick.
