Prestone Universal Flush and Fill Kit to flush radiator

[XJMJeep]

I've never had any issues with the kit and my personal opinion is they work great.
Very easy to install and helps get the crap out of the engine block before installing new thermostats, water pumps and radiators.
Worth every penny if you ask me.

Here's a picture from last summer of me using it before my radiator swap.

I've had one on my car for years. I believed the cap may have heat cracked after a few years,or either I lost the cap and replaced it with a soda cap that cracked. (soda caps fit in emergency but are definitely no good) make sure you're using the right heater hose,(you want to back flush to engine) and I think I read somewhere that after the initial fluid runs clear (that you have to contain to prevent tainting the environment. ) to drop lower radiator hose for complete flush also don't open heater on initial flush I hear it pushes gunk into the heater core,don't use too much force for same reason. Don't know about the validity of these things but I go by them. figure couldn't hurt. Main thing is don't just flush radiator make sure you flush engine block if possible. Hope this helps. Lord knows enough people have helped me. And don't forget to burp the system.

had that happen with my dodge found out i had some junk in the cooling system that when i turn on the water to back flush it fliped up and blocked the flore.then the waterpump started to bog down.fixit by removing all hoses and therm. and freeze plugs and shuving a hose in each one until we found it.
