I have a 2001 intrepid with a 2.7. It had a slight leak in the heater core so I asked the dodge dealer how much for a new heater core. The said with parts and labor it would be about $900.00 because the had to remove the dash. I couldn't afford that much so I went to the parts store to get some stop leak. The manager of the parts store told me about this product they had called blue devil stop leak.

It was $50.00 a bottle but he was told by the rep that it was worth it. So I decided to try it. Well It completely plugged up my entire cooling system. No heat to the heater core. No flow to the radiator. The engine got very hot. I had to take it to the dodge dealer. They back flushed it many times and replaced the thermostat. They said the blue devil came out looking like cottage cheese but the little white pieces were rock hard. They gave it back to me with a $400.00 bill. A couple of days later it had the same problem. Still plugging up. Back to the dealer I went. More chunks of the blue devil were breaking loose and plugging the system. Now they want to replace the radiator, heater core and water pump to get the system working properly. To the tune of $1600.00. All this because I trusted there product. I contacted the company that makes blue devil and they are only going to refund the amount of the product. I really learned a lesson on this one.

Ya. I will NEVER use any stop leak in any thing. Transmission, Cooling, Oil, Tires or anyware cause it will cost you more like you found out to fix what the stop leak screwed up.

Yep, I learned this when I was 17 with a product called Bars Leak or some such name. It clogged up my coolant sys on a 1958 Chevy.

No getting out of installing new parts. Sorry you found out the hard way. :bash:

Huh...I've had good results with Bar's Leak. Maybe I just got lucky.
Same here. I've used Bar's leak with the pellets in it in plenty of vehicles and never had problems from using the stuff.

I wish I would have used bars leak. At leased it only turns to slime and can be flushed out. This stuff coates everything and turns hard as a rock. :cussing:

You shoulda used a raw egg like on mythbusters!
The raw egg on mythbusters stopped the leak, but ya don't know how long it held up, or if it caused other probs such as clogging stuff up after awhile. One thing I know from personal experience, if you don't want to spend the money on replacing stuff to stop a leak.....add one heaping tablespoon of Black Pepper to the system. My brother told me about this....he has used it on more than a few cars of his including his '74 Road Runner with a haul ass 440 that was leaking from where the header mounting stud was threaded in the head. I have used it on my '94 3.3 trep which was leaking from where the timing cover was attached to the block. I also used it on my daughters '89 Oldsmopile lower rad hose to pump connection. All of these leaks were stopped, none of these cars had any cooling problems or heater problems. If you have a head gasket leak or a leak from corrosion, black pepper won't stop it and neither will a $50.00 bottle of magic chemicals. Heater cores don't normally corrode, they leak mainly from piss poor solder joints, which black pepper can stop. If want to try it, add it slowly with engine running but not yet warmed up, then drive the car for about a half hour, you either keep driving or shut it off after that half hour.

Those stop-leak products are a waste of money. I tried that Bars Coolant stop leak on the leaky heater core in my old Corsica. It clogged the heater core, gummed up the water pump and totally f'ed up the radiator.

The blue devil company did agree to pay for another backflushing of the system. But that has already been done twice so I dought it will help. If it doesn't work I will be looking for another car. I am thinking of going with the ford 500. I have had my 97 f150 for 10 years now without one single problem. It purrs like the day it was new. So I'm think i'm a ford man now.
