I was curious as to what the temperature guage looks like on your Type R's in below freezing temperatures once the car is warmed up? Mine only gets to the first tick lately and I'm curious if something is wrong with my thermostat. Oh yeah, its a 97' with 90,000 miles.

 

I would have to say replace the thermo, though I've never been in those kind of temps. I think there was a thread recently about this. The thermo ended up resolving the issue. HTH.

Thats what I thought I'd do. I need to order 90,000 mile check up parts soon so I wanted to see if I should order one while I'm at it from Len.

Mines well huh

 

replace the thermostat for sure. bad thermos make the temp go up and down.

also, how much coolant and water do you have mixed together? more coolant, cooler the car stays, more water, hotter the car gets, and it will get hot quicker.
i have like 60-40 water-coolant. i live in ohio and it was 13 degrees the past couple nights and i havent had any probs running that low of coolant...

 

It depends on how cold it is. If it's below about 20º F, my temperature gauge is usually at the 1/4 mark. If it's a little warmer than that, the gauge usually reads around 1 mark left of center. This is with a Mugen thermostat and 134,000 miles, BTW.

 

mine is always 1 tick below the half mark, no matter if it's if it's 90 outside or close to zero degrees. stock themostat.

I think this answers my question. It was about 32 this morning, its a 30 minute drive to work and the thing never got past the first tick. Time to replace.

I think you have it backwards? The coolant doesn't carry heat as well as pure water does, so, more water is run ya cooler. But, in 13F weather, I would leave it 60-40 like you have it, so it doesn't freeze as easy.

 

do a flush and replace your coolant while you are replacing the thermo as well

 

if you run more coolant, the car will run cooler than if you ran more water. think about it, water boils at 212f, and coolant keeps it from boiling until a much higher temp when mixed, so coolant is what keeps your car cool.

only to a certain degree.... if it was so good....we'd all be running 100% coolant because by the theory you presented, it would prevent freezing but also elevate the boiling point if used at 100%.

Water does the job by carrying heat away....coolant prevents it from boiling.... pressure also does its part to keep it from boiling....

a 50/50 mix is usually ideal for all but the most extreme conditions...but as always...consult your users manual for specific temps....

Mine stays 2 hash marks below middle.... but I run a Mugen thermostat and Fluidyne rad with approx 75% water 25% coolant.

 

Oddly my car runs a hair colder in the summer.
