The stock hood can create a closed system by which temperatures will climb in the engine bay. The vented hood allows the heat to escape but there's no intake effect at higher speeds. Also there's no indication that there's any high pressure zones inside the engine bay to force air to escape through the vents. Does it help? I think it does. It certainly doesn't hurt. As for holes in the back of the hood...that's a discussion that's been beaten to death by both sides. Therefore you are changing the Pressure Zones around the front of car which could effect the volume or air naturally going through the radiator, as the RX-8 book says (or one of them) a lot of work was done by Mazda in this area. I think if it had any beneficial results Mazda would have done these changes in the Series II RX-8. They certainly know that excess heat is the enemy of their rotary...;) Ash |
I meant was there a fix on Easy's car? Did it stop overheating?
BTW, I recently changed my coolant, but the manual said to take out the radiator plug, so I did that, but I had no idea where the Engine plug. I read that it said theres about 10 quarts of the coolant system... but dayum when I was filling it up, it stopped at around 7 quarts, so it was basically a WTF. Anyway, that's my story :) |

Just dump maybe 1 quart of 100% Anti-Freeze, the rest just distilled water. it will probably cost you less than 15 bux. Don't forget your heater core holds coolant too, not having done mine, on other cars I used to open up the temp control to HOT so the heater tap is Open, so coolant will also drain out from core. But, you must leave this open when you warm up engine before you drain. Ash PS:Coolant tank also included in 10 Qts. |
My car will still get hot in the temps we've been having around here lately. Today was cool, only about 112. Compared to the 118 we had a couple of day's ago.
My car runs in the low 200's as long as it's moving above 30 mph. With the A/C on. If I get into stop and go traffic it will get hot. 220's and above. And don't do any spirited driving that just makes it hotter. So the best fix is drive with a light foot on the throttle. |

Oh ok thanks for the info. And Ash I already knew about that, that's why I said there was a capacity of 10 quarts or however you people say it. Litres FTW!
So wait, how would you do your daily redline? It must bring your temps super high! |

So wait, how would you do your daily redline? It must bring your temps super high! I usually pick my favorite spots, where I can add speed in open area's with few traffic lights, it is difficult though as my state is "drunk" on speed camera's, fixed camera's, laser guns, camera's on patrol cars, camera's in plain cars parked, stop red light with speed camera's.. Fu**ing Camera's it is BULLSHIT. Summer time, I still use the same locations, as you know if you do a few changes to red-line you are over state speed laws, so I try an do it around familiar areas and give the car time to cool with slower driving for a few miles, but, this is why you have 'cooling' fans. |
Tru Dat.

I am in the process of making New Oil cooler Vents for the inner guard splash shields..
Got some aluminum mesh and two new splash shields that I will use as standard OEM for Winter, and the opened up set for Summer (with mesh), or when temps get above 25c (80F). I am going to open up the entire venting area on the black plastic shield and put in the mesh. Yes, I know that cooling fans are now available, BUT, I am trying this mod....you need to have flow through of air. It is very easy to change over the shields (summer to winter), only 12 quick release plastic rivets for each side. Will post pics when I do it. |
Sounds good Ash8. Would love to see the pics when your done.
We tried the oil cooler fans here in AZ over a year ago. Did nothing to bring the emgine temp of the car down. Only thing that keeps the temps in control are being light on the throttle and not getting stuck in stop and go traffic. I was on the freeway today about 108 degrees outside. Traffic slowed to a crawl and my temps went to 237. |
/\ you tried a 2nd radiator like mm ?

Do you have AP, can you set your fans to come on HIGH earlier?? |

See the thread below
This really works well and would be a perfect mod to your AT if you only have 1 oil cooler . For your climate and operating conditions you will need a fan as well . A well known vendor on here makes one LOL Really simple to plumb in as well . https://www.rx8club.com/series-i-aftermarket-performance-modifications-23/cooling-mod-idea-155235/ |

yes I did .
I don't see where you say you tried a WATER radiator in where the 2nd oil cooler would go and fitted a fan to that ...... Way more effective on engine temps than fitting a fan to the oil cooler |

I have just cut out the Vent's in the black splash shields (used snips/scissors), will do more later, have not got the motivation, it is freezing cold and wet, windy and miserable Saturday arvo.
Will get it done before summer, should I use rivets or small thread bolts and lock nuts to hold the Alumin mesh on black plastic? i would try to use some plastic thingys like hold the fenders shields in.. (think hot under belly) simple and dont corrode. i guess i have to figure out where you are in aus.. i know it is winter slowing down in greater aus. but dont you have a aus = fla section that is zesty year around? if not i finally found a flaw in you country!!!! ;) beers :beer: |
I found a flaw in your spelling Swoope.
