I'm a tiny bit paranoid and decided that the rather inexpensive ($35usd) X50 display was perfect for my needs. I want to set the upper limit which starts a warning for the water temperature. Would someone please advise what I should set it at?
thanks

I dont know whether this will help at all however on my Autool X60 my coolant temp ranges from 199 degrees F to 206 Degrees F.

199 when just cruising along and 206 after some more spirited driving.

Ambient temp recently was around 40 degrees F.

 

Let me think, the last time my thermostat failed, I started to see the temp rise into the 220's. I forget what temp set off the alarm.

I'd start worrying if the temp exceeded 220, >230 = something's really wrong. Lets see what others think.

thanks, that gives me a sense of range, hoping some others will chime in.

I'm using the X50. My normal temperature is 95°C/203°F (both the X50 and OBDll reader give the same reading). I set the alarm for 110°C/230°F. I keep an eye on it (X50), so chances are that I will see a significant rise in temperature long before the alarm sounds.

Why not just monitor your engine temperature to see what the maximum it reads in day to day use and set the alarm for 1º higher than that?

 

I have my alarm set for 220. If you use 230 there may be damage before you can pull over and shut the engine off.

 

great! I think I'll work with 220~225 for the time being

you're probably correct, going with 220~225

 

Trying to make my life less complicated!!!!
today's low = 31(f) todays high= 62(f)

two months ago the high was 102(f)

thanks for your thoughts

Those look like non-engine temps...
They're of some interest/relevance but it's the engine ones that really matter so what's the situation there?

 

I assumed they were ambient temps.

 

as jackra mentioned, they are ambient temps... as as we all know the operating temps vary based on ambient and load...so, setting an alarm 1 degree higher than the operating temp (at some point in time) would not leave enough variance to account for those variables.

Then the workshop manual doesn't specify a max the way it does for my car?

I was expecting there would be a practical value that would be a lot better than doing nothing.

 

My suggestion was to set it to 1º higher than the maximum engine temperature you have seen - you can increase this value anytime you want if it needs to be higher in summer, for example. The idea is to tailor this figure to your car and your environment, not to other owner's figures.

 

+1 on the above.

According to my workshop manual the only mention of coolant temperature is with regards to when the thermostat is fully open 208 degrees F.

The most I have seen with ambient temps here recently below 40 degrees F has been 206 F on the X60 and that was going up a steep hill accelerating a bit.

In the Summer I am sure it will get a bit hotter.

 

I understand, getting lazy in my old age and don't want to be fiddling with everything all the time. I don't really want to watch the monitor but rather set the temp and hide the entire unit in the small drop down tray next to the steering wheel (USA version). If I hear the alarm will check out the temp.
thanks for everyone's opinions and happy holidays.

Having lived in Austin a few years back, knowing what the temp shows you at it's high rage during the summer (average somewhere around 90 to 98, with those averages going up in the low 100's sometimes), I would think you should know just where to set the high range.
If you haven't lived in Austin during the summer, it will come early and you'll soon know. :-))

?????????????????????????????

For those who have JUST installed the X50 or X60 how would they know that?
