jherrington Don't use stop leak stuff. Period. Just don't. Yes. You will clog things up/ make more trouble for yourself in the long run.

1jeeplvr Well I just got home without any problems.I had a little bit of leakage but nothing too bad.And I didnt need to use any stopleak.Now I can fix it properly.
08-17-2013 06:32 PM
1jeeplvr I just want to clearify that I would normally fix the leak & not use a stop leak,but as I mentioned in my first post Its a situation that I have to drive the vehicle,no time ti fix it properly.
NJO,I AM going to replace the plug.I just dont have the time before I have to drive it (tomorrow).And yes its a pretty easy repair that I know how to do.Last year I replaced the ones that are between the engine & trans.
Im hopeful its not goin to be a prob.I noticed prob 3 drops on my garage floor,over a weeks time.Ill stop periodically along the trip to check it.I really have no other option.

Just because they don't say you shouldn't use it doesn't mean its fine to use... I'm sure they say nothing about shooting a few 12 gauge slugs into the block, but we all know that wouldn't be the best idea.

jsuggs Guess that I just do not know what I am talking about. I have provided the stop leak part numbers for the big 3.

Now can anyone show where a manufacture says not to use stop leak?

jsuggs That is from Ford:

TSB 02-23-07 Cooling System - Motorcraft Premium Gold Engine Coolant - Service Tips

If you would like to check.
08-17-2013 04:51 PM
jsuggs The current Motorcraft Cooling System Stop Leak Pellets, service part number VC-6, used in both Production and Service, cause the yellow-colored Motorcraft Premium Gold Engine Coolant to change color ranging from a light golden brown to dark brown, depending upon the amount of pellet material in the coolant reservoir. This discoloration does not adversely affect the coolant or the vehicle's cooling system components. No repairs are required for this condition. To avoid confusion with regard to coolant contamination, a new formulation of stop leak pellets will be implemented in Production and Service in the near future.

Ha, I remember that engine... intake manifold gasket problems, weak aluminum block problems, bad oil pumps, stripped out bolt holes in the aluminum block. A wonderful 80's triumph of GM eighties engineering. Coolant leaks were nearly a minor issue with that engine when compared to its other issues.

Steve2012 I have worked for a Cadillac dealer for over 15 years, the ht4100 and North Star were both junk, that is why gm sells crap to stop head gaskets from leaking.

Jerry Bransford Yep for emergency use, just like dealers sell spare tires.

If a cooling system is leaking, there is a problem. No automotive manufacturer is going to tolerate their OE manufacturers sending them parts like radiators or water pumps that leak. Well maybe the Italians would.

No, they don't. You tried claiming that before but it's simply not true.

jsuggs Most new cars come with stop leak in them. I like to use the bars leak that is the big dry pill looking one. It is basically like a wood pulp. It is what GM uses in the Northstar engines. It will not harm your cooling system or clog anything up. In my opinion it should be used in anything with a plastic radiator or heater core at all times. That is a accepted industry practice. As everyone should know that even the smallest leak in a cooling system causes the system to lose pressure significantly lowering the boiling point of the coolant.

Best of luck

Jerry Bransford Stop leak in a non-emergency situation is just not something I'd use. Finding the leak & fixing it is a better solution, stop leak can just cause future cooling system problems.

This is a bad idea. Especially if it is a freeze plug. Better get it hot and run it now or get a new one in there before you go. What if you are on the road, crankin the tunes, not watching the guages, and it leaks more then over heats and blows out the plug? Now you are into big mechanic fees in some small town.

Just sayin'.
08-17-2013 02:13 PM
NJO If the freeze plug needs to be replaced, then replace it. Welsh Plugs replacement Its actually not hard to do.

Palmers2000tj Was always told not to use them they can clump up and plug your system up then you have to flush your system out
08-17-2013 12:17 PM
1jeeplvr Bumpety,bump.
08-16-2013 09:12 PM
1jeeplvr Thanks Shoe.Im reading a lot of good things about Alumaseal,the powder.
08-16-2013 09:07 PM
Shoe I used the Bars Leak tablets in my daughter's jeep last December to stop a very slow leak that I never could find. (about a quart every couple of months) Since then it hasn't leaked a drop. They recommended 3 or 4 of the tablets, I only used 2. It probably has at least 8 or 9,000 miles on it since then with no problems at all. I would recommend the big tablets instead of the pellets, and never use any of them if you think you have some exhaust gas leaking into the coolant.
Good luck on your trip!
