hey my 240 is overheating and i don't know what to do or what to replace???????? help me to new to the 240x cars to know how or the place the parts are in.. thanks

 

Are you sure it's water pump? There could be air trapped in the radiator passages.

Just asking before you spend $ on something you don't need yet.

 

didn't you say in the other thread you dropped an engine into your STI.... and you don't know how to replace a water pump, or diagnose a over heating problem?

im not attacking, just seems really weird.

 

hmmm....

 

mmmhmmm

 

hey well i'm overheating too and my coolant reserve is bubbling. I tired EVERYTHING cept taking a look at the head

changed stat
changed radiator
flushed
air pockets


could it be water pump"??

if so how much would be the cost of parts and labor for a 91 240sx

 

water pump can range from like $50-$70
as for labor, i recommend u do it urself, its actually a real simple thing to do

 

need to change it on my s14. my water pump cost 40 bux brand new. everybody told me it's easy so definitely doing it myself. any write-ups or can someone point me in the right direction to get started?

 

drain the coolant, remove fan shroud and fan if u need the space, take off belts and other stuff, then the unbolt the water pump
its pretty self explanatory once u get in there if u know anything about anything

o yea and dont forget to get some silicone sealant to put on the new water pump so it wont have any leaks

good luck and maybe some other people can clear up things i left out with the labor stuff if i forgot anything

 

no need to remove the radiator just drain the fluid...remove fan shroud...my shroud had 4 10 mm bolts and came off in 4 sections with these stoopid little push clips... take off the fan... 4 10 mm nuts...loosen the belt on the water pump and power steering pump... (same belt on my car)...5 10 mm or is it 12mm (cant remember) bolts hold the water pump in place... remove the bolts and pull on the pump... it will come off pretty easy... take a gasket scraper (or razor blade - single sided just in case you need to know that) and remove any old silicone from the timing chain cover where the old pump was... clean it good and then clean it again... you can get a new water pump gasket but nissan techs just use rtv silicone on the pump... small bead is all that is needed... not too much or it will ooz into the water passages or out onto the timing chain cover... put the water pump back into place and tighten the bolts to 12 foot pounds (so they say) or just tighten them till they are pretty tight... remember you are bolting it into aluminum so too tight will strip the bolt holes... let the silicone sit for 30 min befor filling the cooling system... good time to put the fan back on and tighten up the water pump belt and reinstall the fan shroud... refill the cooling system... start the motor check for leaks and purge it of air... and you are done... drive it like you stole it...watch the water temp and make sure you are not over heating...

 

haha nice and detailed there, but i never told him to take out the radiator

 

i dont know why i thought you did... im blonde at times so i am sorry for that... hope it helped him in some way... it is better than paying for it at some shop...besides why pay for it when you can learn to do it yourself...

 

thanks guys, that did help. but before i go into that, i am wondering what brand you guys decided to use. is there even a diffrence? i was told to get either the "japan" one ($) or the NCW (or something like that, cant remember). if it doesn't really matter im going to go with the n one. cheaper. hoping to do it this week, so thanks for the write up...

 

it dont really matter much one is as good as another... people say get the japan one but what is the point other than sayin i have jdm parts on my car??? they all do the same... pump water to help cool he engine... i get mine at autozone...

 

To all those "OMG it's so JDM" people...

... realize that the 240sx was manufactured in Japan using Japanese parts and Japanese assemblers.

The whole car is JDM. Duh.
