Probably a head geasket or intake manifold gasket it it's not leaking anywhere...

 

to do the swap you need the head, bottom end, injectors, exhaust manifold, and a vtec ecu

 

Could it also be that the ratatiors clog tho??? should i flush it

 

flushing it won't help, the coolant HAS to be going somewhere, either leaking out of the radiator, heater hoses, engine, water pump, somewhere, OR if it's not leaking, and you are sure, it has to be going into your cylinders and out your tailpipe. Is it burning white smoke?

 

Your headgasket is probably shot. Flushing radiator ain't gonna help.

 

yep. Most likely a bad headgasket. And I think your spell check and grammar check is broken too.

 

yes my spell checkers f**k no white smoke no leaks im sure so head gasket how much for one or how do i fix it

 

Get a top end gasket set (because you will need more than just a head gasket) from a local shop or ebay or something, and you will basically just have to remove the head and replace the head gasket and all the other stuff that comes with that job.

There is a lot to it though, and I don't think you should do it yourself. IMO you should take it to a shop, but if you want to attempt it yourself, order a helms manual from http://www.helminc.com , get all the tools you need and be carefull.

 

Is your car smoking ? Check your oil. Does your car smell like it is burning radiator fluid, youll know it will smell bad. I think its a head gasket if youre not seing leaks anywhere.

 

I vote headgasket

 

it probably is your head gasket, but if you've been driving on it for a while like that, the rest of your motor may not be up to snuff either

 

doesnt overheat all the time jus sometimes out of the blue maybe bout i would say once a week give or take a day or too it hasnt overheat in a while tho

 

if you're losing fluid... I would say headgasket. If you're NOT losing fluid.. then probably your thermostat starting to stick and going bad.
