So i am trying to bleed my coolant system of the excess air one weekend long ago.. And i break the screw, now i can't get another one because they are not sold seperatly, you have to buy the whole radiator assembly... Screw that, now how to i bleed and get my coolant system pressurized... Anyone know where i can get a cap? None of the junk yards want to sell them either because "what if some one wants to buy the rad" I was thinking of plugging it with a bolt and a rubber o-ring to keep pressure... How are systems bled with aftermarket rads?

Are we talking about the screw at the end of the radiator that tends to STRIP LIKE A **** ALWAYS?!? I hate that screw let me pull you up a mazdatrix part number for just the screws its like 20 bucks tho, gimme a second.

Edit- its 10 bucks, that should be it, its 2 plastic screws that are at the bottom of the rad and at the end of the top of it to the left right?

haha!! thanks alot bro.... I'm going to YELL that number to those retards

 

mazda canada should have it, i put in a different rad a few months ago and it was about $12.00. Some times they cant find the proper numbers, i called to see if they has stock on some spark plugs the other day and they said they didnt carry them, i just laughed and gave him the part number and told him to remember it b/c i was going to get more in a few months

 

It "tends" to strip when it's mistreated. It will only strip if you overtighten it and/or use the wrong sized screwdriver. It's just plastic, so you need to treat it with a little respect.

An easy way to undo stripped plastic plugs is to heat up the tip of a flat bladed screwdriver and gently push it into the plug just far enough that when it cools you have a nice slot to undo it with.

 

Or cut a nice slot in it with a dremel.

 

i almost toasted the one on my koyo, that would have been real fun to find a replacement for that guy.

 

ya when you put the new one in it doesnt have to be that tight, it has that little rubber O-ring.
