I used some cause I thought I had a radiator leak but it was the water pump. But someone told me that stuff was really bad

 

it is designed to plug up little leaks in the coolant system, unfortunately it also plugs up heater cores and the small passages in the head/head gasket

 

I agree. Always best to find the actual "root cause" of a leak and replace/repair that component.

 

So now that I've fixed the problem how do I go about cleaning it outta my system?

 

You don't. It's in, and anything that could clean it would also cause corrosion on anything else in the system, potentially causing more leaks. Leave it be but don't be surprised of you end up having to replace your heater core.

 

Wut? Flush the hell out of the cooling system with the heater on full blast. It may take 3-4 times but it should all come out. Both jeeps I've had came with some sort of stop leak in them, but eventually you can get it all out.

 

Alright I'll try that can I just use water to flush it?

 

Buy the flush stuff at any parts store and follow the directions

 

Aight

 

I had it in my 98 blazer and could never get it all out. heater core, two water pumps went out in it cuase the crap.

We even did the procedure where they rot out your radiator what ever its called.

This was back when I was a green mechanic so I had a shop do it all. Never did get the stuff out. I just ended up selling the heep.

 

What brand? A little won't hurt....Many O.E.M's have used Bars tablets in every vehicle before it leaves the factory!

 

Stop leak is a non dissolvable coagulant, else it would not work in a water based cooling system. You may flush the stragling amount out, but whatever has adhered in the system is not removable with a basic flush. Which you've basically accomplished by replacing the water pump. Yes, you should back flush the heater core. That can be done with a water hose. Bit you won't get all of it out.

 

I agree with this. Do the best you can with a flush of the radiator and heater core and cross your fingers.
