i'm gonna do this soon... need some opinions. my car is a daily driver in FLorida... i'm sure my 8 would be happy w/ a cooler engine... i already bypassed the coolant from the throttle body...

The rotary engine is basically a sandwich of different metals. That makes it very susceptible to corrosion. To keep corrosion at bay you want to run AT LEAST a 50/50 coolant mix, and change regularly. You need the corrosion inhibitors.

Nice guide, looks like a very easy DIY. I noticed my coolant was close to the Low line and I topped it up to the top line using some Volvic mineral water. It only required a very small amount of it but some people have told me it is very mad for the engine due to to the additives in mineral water. Anyone care to shed some light on this. Might drain the system but I don't know if it worth the hassle and expense.

Don't worry about it. You only added a small amount of minerals.
Minerals leave depsots and cause corrosion. Hence the need for distilled water.
People have been using tap water for years. Don't worry about it, unless you a nut like we are and must have things perfect... but then again if you were lie us you wouldn't have to ask us.
Take a general automotive shop course to start with. Find someone who works on cars help them and learn.

Yeah, I know that, might just drain and refill it anyway. Looked at the Mazda workshop manual and it suggests just draining from the the radiator bolt, however I have seen people use the plug near the sump. Do most of you just use that or just both?
Does anyone actually drain and then flush the system with anything before refilling with coolant?

BACK from the dead I say!!! (1 day short of 1 year)
Question: If I remove the drain plug on the radiator, pop out the hose, AND remove this bolt while it's up on a lift, will that pretty much drain out all the fluids I need?

Hey guys, I will be changing my coolant as well this weekend... the same time as my turbo installation. Two questions.. Redline WaterWetter recommends using distilled water + waterwetter ALONE (no antifreeze).. they report that using antifreeze + waterwetter will increase the temperature about 20 degrees f.
What do YOU recommend?
What do YOU recommend?
read the first page here. here's a little tip i must include for those running any high performance radiator fluids such as redline ONLY. severely altering the ratio of water to coolant (50/50 mix) in none racing environments and for prolonged use may affect seals in the engine and prematurely wear out the water pump.
my opinion on this is to not go below 35% (35% coolant/65% water) and 30% is where i draw the line if to even run it for weekend racing.
please consider that. and i assume NJ is a cold state...may not be worth your time on this mod.

Hey guys, i've been considering to change my coolant but its too cold over here in the UK to attempt any thing my self at home at the moment, however i have found a coolant leak in my car. I have been topping it up with water now once every 2months so far, my dealer didn't find the leak tho they only had the car for and hr to replace the starter motor. Is it still safe to top it up until i have any money after xmas to find the leak, fix the problem and do a coolant change?

If anyone wants to change the washer, the part number is 9956-41-000. It's a special order part, but I recommend changing them everytime as my washer was melted last time I got the engine bolt out.

I've only ever used a 50/50 or 70/30 mixture of coolant and water....never had any probs weather it was this car or any others and in the snow/cold and hot of FL

What do you guys use and how much of it to 'flush' the system before adding the 50/50 coolant/distilled water mix?
I assume distilled water until you see it come out clear?
Thanks.

After draining from the engine bolt, it will get over 95% of the coolant out.
Then I will fill the car with distilled water and maybe 1/2 gallon of pure antifreeze to lube the water pump. it takes about 2 and 1/2 gallon in total. idle for 5 minutes, fill up to the MAX line with distilled water if needed. then I will drive it around for 15 minutes or maybe 10. shut it off for 30minutes before I repeat the drain n fill for 1-2 more times.
After the flush I just fill it 2 gallons of 50/50 into it, the rest is distilled water.

I prefer the Prestone 50/50 pre-diluted coolant and it lasts a loooong time now.

I tried Peak, Proline, and Prestone.
For some "weird" reasons. Prestone gives me the lowest water temp readings. it could be just different day, weather, humidly, driving mood, etc. but hmm.
Proline is probably the cheapest, maybe 5-6 bux a gallon, Peak is doing a promote @ Autozone with rebates. I got my stock of Prestone at some buy 1 get 1 free sale. comes out to be around 7 bux a gallon, no rebate required, not bad.

You do know the OE coolant is rated for 10 years/120,000 miles right?
