The only real fix for the coolant sensor failure is replacement of the entire bottle. There is no function issue if that is the problem, just means the light will be on when it shouldn't be.


That being said, if the coolant level continually needs to be topped off, either there is a leak somewhere that should be found, the car is overheating too much and coolant is overflowing out of the bottle (which the overflow tube is right above the power steering and radiator fan connectors, which can cause them problems), or there is a failed coolant seal in the engine, and it's only a matter of time before engine failure.

Not to scare you, but just things to look for or rule out.

 

Hi, I'm a new (to me) owner of a 04. After reading a few of the earlier posts about the guy buying a 8 from a guy that has all his records for maintenance. I too looked at the carfax before buying to make sure it wasnt wrecked etc.. but im assuming the previous owner of my 8 did his own maintenance.. and he really only drove it 7k miles a year for his 5 years of owning it.. (it has 59k on it now) say in the future if my engine did crap out (god i hope not) would mazda be difficult with honoring the 100k/8 yr warranty?

second question.. would adding a air intake to the car help with clearing carbon out of the motor.. i've followed everything to a T that people have talked about on this website.. topping off.. checking oil.. not shutting the car off without running it for 5 mins.. red lining once a day.. i know red lining will help with clearing carbon out.. so basically.. would adding the air intake add to the help of red lining?

 

Unfortunately, they probably will be. Doesn't mean you are out of luck though, really depends on your local dealer, and how reasonable they are.

No. The redlining helps to clear carbon because of the high V/E, basically high heat, high air flow, high fuel. Requires high load on the engine.

Air intakes don't really add anything significant to air flow or fuel flow that alters this, for good or bad. If you want to do something to keep the carbon clear, seafoam once or twice a year.

 

Depends on the dealer from what I've observed...find a good recommended dealer from here, because some of them (especially those that deal with Rx8's alot) seem to be less strict on this than others. The other option is to just doctor receipts, which I'm sure more than one person does. The short story is, this goes on a dealer by dealer basis.

Redlining is the best thing for carbon. I PERSONALLY have seafoamed my car once (to remove carbon deposits in engine) and I also premix.

Also, nice job to RIWWP making this post. Needs a sticky.

 

good idea riwwp, this should be a sticky.

 

Only Mods can sticky... And I will be C/P this on every new thread made...

 

Great thread. If it doesn't become a sticky, we can bump it every single day until people get pissed off.

 

Best thread ever! Well done RIWWP !!!

 

Thanks.

New owner question threads are popping up everywhere. When I glanced at iSpy last night, there were 4 new threads from new or prospective owners on that list alone. Most of their questions are repeats or similar, and there wasn't a place to address them already that wasn't buried in threads or split up between stickies.

 

yah, I reiterate the need for this to be stickied. Awesome post RIWWP.

 

I've been linking to it in a lot of newb threads as well. Great work RIWWP!

 

Registered just so I could give you a huge thumbs up for this post

I recently purchased my RX8 about 6 months ago and used this site extensively for research. While all the info can be found, a lot of it is spread out and some is not updated for series 2, or otherwise doesn't indicate if it applies.

Having all this in one post and up to date will really be helpful for new people.

Thanks!

 

Great info on potential new owners. Just wondering if the 8yrs. 100,000 miles of warranty applys to 2009-11 rx8? Would consider buying the 8 instead of an FD.

 

No it doesn't hopefully they will not need it do to all the changes made to S2.

Great thread RIWWP

 

Yes it does. It applies to all RX8's. My dealer just told me.

 

^^^ Well hes wrong

 

Really?

Mazda Website:

RX-8 Rotary Engine Core Limited Warranty Extension

Mazda Motor Corporation is extending the warranty coverage on Rotary Engine Core Components on all RX-8 vehicles produced after the 2004 model year. The warranty coverage for the Rotary Engine Core Components is extended to 8 years (96 months) from the original warranty start date, with a 100,000 mileage limitation. The following is a list of components covered by this warranty:

Rotary Engine Core
-Rotary Housing and Internal Parts
-Internal Seals and Gaskets

 

maybe im wrong, i just never remember them saying anything about the series II rx8

 

No, it covers 2004-2008 models. See Attachment.

 

Woot Woot, im not wrong, whew... scared me Alnielsen

 

But, you are wrong. You spelled my name wrong.

 

Says an attachment before the '09 model year was released .

Explain this: http://www.caranddriver.com/news/car...ranty-car_news ?

 

Fixed

 

Just to clarify with regard to warranty issues. Does Mazda usually look for all records from day 1 of the car? Or can I start keeping maintenance records from here on out in the event it craps out @ 99.9mi and still be honored the warranty?

I am looking @ a used '07 GT @ 42k mi w/o maintenance records in hand. Just a carfax. Thanks!

 

It really depends on the dealer. I have heard of some asking for all the records, and trying to use 1 missed record as a reason to deny. Others aren't asking at all. Most seem to only look for the past 10-15k of records.

If this is a hanging point for you, then stop by the dealer (or dealers) that you might have to use, and ask them "if I get this 8, will you require records from the prior owner in order to honor the warranty?"
