Looking for the part # and cost for a thermowax

 

Not sure what the part number is or the cost but you live in Victoria it never gets that cold there just do the throttle body mod and screw the Thermowax all together, you will save yourself the cash plus gain some horsepower.

 

Why don't you just ring Mazda?

 

Is there someone out there that will sell ASHERWOOD the thermowax that you took out of your car???? You won't be needing it anymore and you can save him some dough while you make some dough.

 

I have an extra pm me it's off of an 87 but should be the same sell it to you for 30

I know that everybody in Canada thinks that it never gets cold in Victoria, and I guess that compared to the picture of the snow that was in Calgary this past weekend you're probably right, but I always try to make the factory piece work as designed before I start tearing the various parts off. I guess that I'm picky, I want lots of horsepower, BUT, I value drivability above all else. Thats' why I working on the stock TB.

Correct me if I'm wrong but doesn't the TB mod remove the set of plates that sit ahead of the secondary throttle plates and act as a choke? I like to warm up the car a bit to get the oil flowing then drive away, if by removing these plates the car looses drivability I'll pass. One of the things that I miss about driving a car with a regular engine is the lack of torque when pulling away from a stop during normal driving. These rotary engines are peaky enough.

I was just looking for a source in case I could not adjust the thermowax I already have (It seem to have the correct range of travel) it was probably miss adjusted by someone who didn't really know rotary engines.

Thanks in advance for any offers, Canadian sources are best due to the exchange and customs hassle.

As for calling Mazda, they always want way too much for parts for an 11 year old car

I tried that with the wiper assembly (something that IS definitely needed on the westcoast!) and nearly died when they told me the cost!

 

I spent a couple years going to school in Nanaimo so I know what the weathers like. It rains alot but is NOT cold by any Canadian standards. I know how you feel about making the stock parts work like Mazda designed, I was the same way when I first bought the car. Then I realized in order to keep replacing stock peices with stock pieces I would eventually need to sell my right ******** to pay for it all. I live in Calgary and I am sure you have some idea of our winters. There is more than a couple guy's here who have removed the thermowax with no problems. You can remove the thermowax without removing the throttle plates. When you fire the car up in the morning or whenever it will idle at 1500rpm just like normal then once it warms up it will drop to 750 no problem. I would ship you out my thermowax but it's fried which is why I scraped it in the first place.

I guess it comes down to this: If you can afford the replacement from Mazda then go for it, or if you can find a used one in decent shape go for it. If you can't then I wouldnt worry about it and just scrap the old one all together.

 

Hmmm, I'm going to play with the TB tonight, If I can't get it adjusted to work, I may take your suggestion and remove the thermowax altogether.

If I remove it, I would guess that I would have to remove the cam and follower that it operated as well, right?

BTW, I used to live in Calgary, so yeah I know that we out here on the island have nothing to complain about when it come to the cold!

 

Yup the thermowax come right off. You will need to remove the fast idle cam (no big deal) and since no more coolant needs to flow through the TB to get to the thermowax you will need to re-route the coolant line, that's all ther is to it.
