i was just wondering if the flushing kits are any good? i just wanted to same me the hassle of removing the block drain plug and knock sensor. however, if the kit is not as effective, i will try to remove the sensor and plug. thanks

 

open the draincock, stick a hose and radiator and call it good

 

yeah, i just wanted to get the coolant out of the block but i guess thats not going to happen. thanks

 

I tried using a flush system before I went from the orange to the green coolant. After I thought it was flushed. I had spent atleast a couple of hours filling, running the car till the stat opened refilled, drained and repeated I don't know how many times and never got out all of the coolant. And because after doing all of this I went to the green coolant. I had drain the block because I started having sludge build up.

Z~

 

Forget the kit, like mentioned above draining the radiator and flushing just that is suficient, but like ZLT195 said you can use this method and still wont get all the sludge out. sometimes its not a good idea to go overboard with the flushing, especially if you have a car with a lot of miles or its older, it can only lead to problems when all the gunk and sludge that is clogging up the system disapears, leaks can arise. I usually flush out the radiator pretty good and the block twice, then i call it quits.

 

Well the flush kits are good if you now how to use them but sense your car sux it is not worth doing. You will always see the back end of the 87 IROC-Z lol

 

take out the drain plug, thermostat and knock sensor....

then put in a garden hose until it comes out clear... or ALMOST clear...

 

how can i get to the drain plug and knock sensor. it seems they are up there unless i am looking at the wrong thing. i have pics from shoeboxs site but mine is so dirty underneath their its hard to tell.
