    DIY Pressure Flush Cooling System

    Anyone know of a good way to pressure flush our cars without cutting the hose and installing a kit?

    I always kept a seperate piece of hose handy and installed it that way to flush it so it wasn't permanantly installed.

    I need someone to confirm if what I did will be good or not.

    I bought a kit but didn't use it. I did, however, pull out my entire radiator to clean the crap off the front, which only took about 10 minutes. I then started the car and let it run while I had a hose on full force into the fill inlet until I could only see water coming out of the upper hose. Doing that took a couple minutes. However, I did not see any fluid coming out of the bottom hose which I'm assuming is fine since the thermostat didn't open up. Do you think the heater core was also flushed by doing it this way? It only took me 1.5 hours to do the entire thing and I didn't have to mess with the core hoses.

    Input?

    Part of flushing the system is flushing the radiator.

    couldnt you just pull out the thermostat, drop both radiator hoses and flush water through the system? (i.e. a high pressure hose into the top hose)

    I flushed the radiator after I removed it, I have a firehose type nozzle and it fit perfectly snug into the the inlet so I flushed it with the hose.
