I used Bars(heavy duty) on my 97' Wrangler to stop a small radiator leak and now it runs a little hotter. Before i used it, it ran like it always did, same temperature for the entire time i had it (8 years). Now it's about twenty degrees hotter than normal. That's what happened to me........

|saharajeeper1||I bought this jeep used with about 90k on it and from the wholesale lot where I work. It ran well and I took it to Trick trucks to get it looked over to see what all was wrong with it before I bought it and they never mentioned anything about the coolant. I agree the brown is probably rust scale but I think the sticky goo is the Bars stop leak. I really just want to get it cleaned out enough to install the new radiator and run coolant flush through it without clogging the new radiator. I'm thinking about taking a dish scrubber with a handel through the t-stat hole to loosen the goo and sray out with a garden hose. What do you think?|

|KSCRUDE||I have used bars leak for years and have never had any problems. 2 weeks ago I put in large bottle of heavy duty in a 97 ford f150. It stopped the leak and nothing else. Also can of motor oil stop leak. Then last saturday I traded it in on a 2008 ford f 150 so all is well. I had put a can in the 97 about a year ago and it worked for a long time. It had a dam v6 so it was time to go. Traded for a 5.4 V8 with 32 k and it runs like new.|

curious, but have you never changed the coolant? the brown stuff is dirt and rust scale from the cooling system. usually a sign of neglect. bar's will leave that grey goop, but the brown slime takes time to build up.
to flush the goo from the coolant passages in the engine, you'll probably need to pressurize the system. might be a good idea to let a trusted mechanic handle it.

I've had a bad experience with Bars as well. It clogged up my heater core though. I had to isolate and backflush to get it cleared up. If you can fanagle it, "seal" the hose to the lower radiator outlet and leave the cap off to let the water out. The pressure out of the hose can lossen it. At least it did for me. It took about a half hour to get mine completely unclogged.
It was easy to seal the garden hose to the smaller heater core hose. I'm sure getting a seal to the radiator would be a bit more difficult.

|JDsDream||Are you sure that it's not oil in the coolant? Have you checked the oil to make sure that it isn't the same brown goo?|

|Dylanjwhall||i don't see why using a garden hose would hurt anything all you're really doing is acting as a radiator just not recycling the water the only main problem would be when you go to start the jeep i'm not too sure what would happen the hose may not supply enough water|

"Bars Radiator Stop Leak" Clogged radiator
I have a 2000 TJ 4.0L and it had a small puncture in the radiator. A friend recommended Bars stop leak so I went to a parts store and picked up Bars heavy duty stop leak and used as directed. It seemed to stop the leak after I used it. I drove about 15 miles and overheated. Pulled the radiator cap and the pellets turned into this gelatinous baby poop like substance. Very sticky. I tried using a cooling system flush and tried to refill the radiator. The Radiator wouldn’t take very much fluid (think its clogged). I tried draining and re filling several times then I replace the t-stat. When I installed it I noticed all the hoses have a thin layer of this brown goo on the walls. I looked into the engine through the t-stat hole and it looks like a gooey cave in my engine. I bought a new radiator but I'm afraid to install it with all the crud still in the engine. Everyone says to backflush it but nothing will flow through the old radiator. I even tried taking my air compressor to the bottom hose to see if it would loosen any of the gunk with not even a bubble from the top of the radiator. Radiator has to be clogged.
How do I flush the engine without using the radiator? Can I use a garden hose through the t-stat opening without damaging anything? Or could I install the t-stat housing without the t-stat and just fill, run the engine for a few min. then drain? I'm at a loss. I have general tech knowledge and I'd rather do the work myself and save some coin. Please help!
