hahah my car still runs strong.. rite now its fine its still shoots up but not as much as before cuz i put my fan clutch back but i just need to get rid of that clogged ugh !

 

I know, I know. Why don't you get an aftermarket temp guage and not rely on the stock piece of ****?

 

that copper stop leak stuff sticks everywhere. if you had air bubbles in your system and the stock leak came into contact with it it woulda solidified into a big glob of copper.

you shouldnt be running a clutch fan and an efan. do one or the other. i prefer clutch fan if yours is probably working. for the efan do you have it wired to a thermoswitch to turn on and off at certain temps? do you have the stock underbelly pan on the car? from what it sounds like if your efan was running the entire time while on the freeway it would actually impede air flow to the radiator.

 

well if one of them runs by itself.. my temperature still shoots up... and my efan has a termostatic control ... and my efan blows away from the radiator not in.. i dont know wat to do.. sometimes its good temp.. sometimes its not.. especially at night when i drive it my temp shoots up like crazy... i think im gonna get it flushed agen next week when i get my pay check and as for the clogged i dont know lol

 

maybe i'll do that .. ima look for one then..

 

let me know what they say about .. hopefully nuttin major

 

If a coolant system able isnt able to build pressure when the temp rises it will overheat. What kind rad cap(mazda I hope!) are you using? Does the clutch fan tighten up as the temp increases? Any bubbles come out of the overflow when the car is running? What ratio of water to antifreeze 50/50 or better? (meaning more water to coolant 70% water to 30% antifreeze is best in our hot, non freezing climate IMO) I would pressure test the system as my next step if I were you.

 

You Still haven't answered wether you have a under pan tray or not... If you don't, chances are thats the problem.

I take it from the lack of answer, for the three times it's been asked.. that you do not have a under pan tray.

 

im sorry... what is that... what does that do

 

i got the cap from pepboys those stants... im not sure about the fan clutch i never really noticed it im pretty sure it works... and no bubbles comes out... and i use the regular coolant.. i put more coolant thatn water... i think its because of that stop leak thing.. i never had a problem before.. till i put that stupid thing

 

 

its my first rx7

 

is your halogen fluid full?

 

its the plastic pan under the engine bay. helps to direct air through the radiator instead of around it. go get an OEM pressure cap as well. if it's STANT brand you'll probably have problems with holding pressure.

also water is better at cooling than antifreeze so you should have at least 50% water not under 50%.

 

oh ok thanx i'll try to do that... .. i'll let you guys know wassup

and yes all my fluid are fine.

 

Man this suck I heard the koyo's not reacting to well on the 7's we modifed our koyo's for that reason. But check the clutch on the fan with the car at idle if you could stop the fan with your hand and yes i said your hand then it's no good use a towel and just press down on the fan shroude

 

i havent heard anything wrong with koyos on 7s except for a bad batch a few years back where the flange for the radiator cap was warped.

 

wow.. ! i shouldve just bought me a stock radiator.. cant go wrong with that...

 

stock radiators can crack and explode since they have plastic endtanks. if you had a stock one and got too hot you'd probably be buying another one right now. nothing wrong with koyos other than that bad batch years ago. i dont hear any complaints about them other than you 2 though Most likely it's all that block weld stuck in your system that you'll never be able to get out with replacing tons of stuff.

 

I got a koyo and I havent had any issues except over cooling at high speed IE over 110, and this was with a stock fan I could stop with my hand that was missing 2.5 blades due to hitting the shrowd, which was cracked and missing a spot on the top so the fan would clear. IT STILL NEVER OVER HEATED, or ever even got more than a quarter on the gauge. Now I got a efan as of last week and now it is stuck on the t stat temp with a 2100 CFM 16 inch new from Jegs, 71 bucks shipped, killer price for a good fan IMO. I am now looking to fab up a nice ALM shrowd and mount the fan a few inchs off the koyo( it is mounted with no shrowd right now) Stock rad SUCK ***, that has been my first mod for both of the 7's I have owned. BTW you can use a s5 fan which has more blades and works better than s4 if your keeping the stock setup.

 

No problem with my koyo either.
