simple thermostat help

[frosti108]

i finally took apart everything to do with cooling on my 92 240sx. i drained all the coolant, took off the waterpump and thermostat, and i was about to take the radiator out but i had an idea.
i suspect the thermostat could be in the wrong way. could someone please please quickly tell me which way the freakin thermostat goes in?

the waterpump is good and the thermostat new, just might be in wrong. also i just found out that my radiator is a koyo copper :)

help please!

On my KA24DE once you've removed the upper and lower hose, and removed the two brackets on the top of the radiator that hold it in place the whole radiator lifts right out. Are you talking about on the top or bottom of the radiator? Just take off the 10mm screws that attach to the brackets on the top of the core support, then pull the brackets off.

What kind of cooling problems were you having?

Try this.. Flush out the radiator with water and/or one of the many flushing agents you can buy. You can also drop the thermostat into a pot of water, then heat it up on the stove. Use a thermometer to monitor the temperature, and make sure the thermostat opens up around 180-190 degrees. This will tell you if the thermostat is "good", I've seen quite a few posts on here where people have bought "bad" thermostats from autozone/checker/etc...

edit: and as many have said before, make sure that jiggler valve goes on the top when you reinstall it. That valve allows air bubbles to be purged from the cooling system, even if the thermostat itself is closed.

lol me not understanding the radiator was just me being stupid and caught up in the moment :cj: haha anyways yea a few hours ago i boiled the thermostat and put it back in, took out the waterpump and inspected for any defects, good. took the rad out and ran a hose through it, good. put it all back together and filled with water, letting all the air bubble out... took her on the road and shes a lot better than before. still wants to overheat if i really get on it tho :doh: so tomorrow or tonight im gonna flush it over and over again with the hose until i see fit. than ill throw in the distilled and some antifreeze and get the air out and it should be dandy. i hope...

thanks for the help people i really appreciate it. :bigok:
sweet smileys on this site btw lol

Okay you might also want to use some Redline Water Wetter along with your water/antifreeze. It improves the heat transfer properties of the water, and provides slightly improved cooling.

Did you bleed the air out properly? Make sure the car is on level ground and cool, open the radiator cap and open the 10mm bolt that is to the left of the valve cover on the intake manifold. Now add more water slowly to the radiator until the water starts to pour out from the 10mm bolt hole on the manifold. Put the screw back in and recap the radiator and you're good to go. Failure to do this results in air pockets trapped in your cooling system, leading to overheating! <-- Speaks from experience.... :)
