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.

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.

The new bodysyle (99-07) is bad about doing that also. We see alot of ranchers around here that are full of bugs and grass.

I'am too a believer in cleaning the rad. I pulled mine out this week as well just for the hell of it and I was very surprized too see how dirty it was, dandilion stuff, grass, leaves, many bug parts I could not see thru it , and now after I've cleaned it I can, and it is not a big job at all just a few hours, the only problem I had was the bottom hose clamp, i hate them factory springy clamps.

Menno.

Mine looked like picture one, and something no one here mentioned, I bet your A/C works better now too. I'd still look into the upgrades, you can do them slowly, one or too at a time but for sure do them all. Never hurts to have too much cooling when driving(or sitting) in the hot summer days.

wow. for anyone out there thinking "mine doesn't look that bad... will this still work?" the answer is yes. I pulled and cleaned mine and it looked NEW compared to this, I still noticed quite a difference in cooling while towing.

I'm with you, Bowtie... I figure this is one of those addictive things, like adding power. You do one mod, then another, then another...

Clean first, do thermostat. You'll want more. Clutch, fan, HO Water pump, maybe 97 dual-therm crossover... by then you'll be ready to clean it again!

The good thing about doing cooling mods is it increases the chance of having to do them again... doing power mods actually decreases the odds of you having the truck long enough to do them again. LOL.

There's that fine line between WOW and ka-BOOM that most of us tread...

Cleaned mine and added some water wetter when I refilled the system now it runs easily 15Deg/C cooler and the weather has been very hot lately. I'm sold on cleaning the rad!!!!

Great pictures Yikes,

I always thought my rad was clean and for the most part it was, however your pictures show that it's not always the rad that gets dirty, but it is the spaces between the AC condenser and the oil and transmission coolers. I finally did mine a few weeks ago and when I pulled the oil and transmissions coolers forward mine looked just like yours. At that point I realized it doesn't matter how clean your rad is if the air can't get through the two coolers stacked in front of it. Today I just installed a pair of 180 F thermostats, I think they will make a big difference also. Good luck towing.
