Pasty Coolant
I was checking the radiator fluid, reserve was low/out. Then looked into my radiator and it was paste coated inside! Pretty sure someone poured in like a stop leak or something?
Anyone experience this? Also do I have any other worries other than just replacing my radiator?

My po poured in some copper colored stop leak. When i pulled the cap there was a 1/4" of that crap on the bottom of the cap. Not to mention the slimy crap all over the neck. A new radiator is $115 at autozone (got a new one in the cab right now to put on today). So to try to fix a leak he gummed up and screwed the cap up, screwed up the tstat, and never told me about it still leaking. Granted it was 2 gallons over a year. I just found it about a week ago.
If people want to try a stop leak why not just crack a couple eggs into it. They can seal up a pinhole too but wont screw up everything else.

Eggs, oatmeal... anything like that is going to clog up all the passages in the heater core, head AND radiator.
Some people suggest ground black pepper.
Sounds like somebody mixed Dex-Cool and made sludge in there.
Me, I'd rather find the leak and fix or replace the bad gasket or part.

Good enough for me. The egg thing was reported out of petersens 4wheel magazine and a way to get back home after a small leak on the trail. They also statef it would dissapate into the coolant.

After what i found today from that stop leak crapmy advice is to flush the system with a hose.
I changed my upper and lower hoses about 3weeks ago. So quite a bit of liquid drained out when i pulled the lower hose. I refilled with a total of 1 3/4 gallons of 50/50. Today i did it while it was warm. Had obviously lost some over the weeks from the leak. Started pouring in the 50/50 i had drained. Got about a inch left and i start seeing all this slime and sludge and chunks of stuff in the last bit. Took my shirt off and strained out about half to 3/4 of a skoal can of that stop leak stuff. To beat it all it never sealed the leak. Next week im pullin the tstat. Its workin good but after all that stuff and for 20 bucks ill change it anyway.

Going to be changing it next week, and anything else that needs it. Bought belts might as well change them while radiator is out. Any other regular maintenance that might be easier with radiator out?

Not really. The upper and lower hoses maybe. This thing is easy to swap 2 bolts for the fan guard and 2 for the radiator. Take hose loose from water pump and tstat and lift. Takes about 20 minutes.
