Radiator stop leak for heater box leak?
I've been smelling hot coolant in the cabin when the heater runs on high temp, and I'm wondering if a radiator stop leak would work in the heater box. Anybody with a specific product recommendation?

Man that's hard to hear. Never used any rad stop leak so I'm not really sure what that stuffs about. Just so I'm getting this right, by replace you mean take the whole dash off, and by bypass you mean bye bye heat?

PO didn't let us know what kind of vehicle he is having problems with. Could be a Grand, early, mid or late XJ. Each one has its own heater core fixes...

Alumaseal won't gum up anything. It is not a permanent fix, but it can buy time, and won't hurt anything.
How much time? Depends on how bad your problem is. Anything from a few days to a few years.
The only 'permanent' solution is a new core, of course.

From what i have seen myself in person yes it does gum up the coolant passages in the engine.I have pulled the head off a car or two that someone used a stop leak to try to fix a blown head gasket.Most of those type stuff are a nasty bandaid when you have bigger problems.

I was working in a service station when "Silver Seal" first came out. Salesman had a galvanized bucket that he punched holes through with a screwdriver. Put water in along with the product. It definitely stopped the leaking. Don't know if it gums up or not but I can see it blocking passages. IMHO maybe under some kind of dire circumstance I'd use it but only if it was a had to situation.

Well, can't believe I forgot to mention I'm in a '96 XJ.
I'd sure like to believe a stop leak would work but from the sounds of things I feel like I'd be taking a chance. Is that Alumaseal somehow different from other stop leaks?

Heater core isn't all that bad on a 96. You do have to discharge the aC system though.

Yes, if you use it you should probably flush your system when you finally do the repair, but that's a good idea anyway.

[QUOTE=cruiser54;3377977]Alumaseal is a fine powder.
SilverSeal (silver in color) was also a fine powder. Later on there was a bright copper colored fine powder product. Then Alumaseal. Anyways if it can stop up a screwdriver size hole I'd be leery unless I had no alternative at the time.
