250 Correct coolant temp

I’d love to know about a secret menu built into the DIP somewhere. Even RS Monitor doesn’t tell you; it gives you oil temp though.

That is the correct temperature reading and I believe equates to 90 degrees. I’d be worried if it didn’t lol!

If you had proper diagnostics that would tell you.

 

Not sure about secret readout but that image shows typical thermostat failing to close correctly resulting in engine hesitating at high rpm

 

Mine sits in exactly the same position

 

Perfect time to change stat then

 

I thought the temp gauge sitting in that position was normal. Does yours sit bang on in the middle then?

 

Yep, when showing as in image above engine fires up and runs fine until start to press on then at around 5.5k and up engine would hesitant with gentle cut out. Changed stat, needle now pointing straight up, engine goes upto 6.5k smooth as with zero hesitation

 

Mines a bit to left, getting it done start of April

 

Mine sits at approx the same position (and always have), and according to OBD data, it starts rising at 50C and is at ~85C at the position in the photo. The needle doesn't move much (if at all) when temp changes some few degress, however.

 

Mine has sat like that for the last 6 years.

 

Would be interesting to change anyway just to see if needle moves, am noticing few these now with off set display. Problem is car runs mostly fine just that little hesitation when pressing on. Mine sat as in image above for around 5 weeks and kept telling myself it’s just the cold weathers but it wasn’t.

 

I changed my stat earlier this year when it was sitting just below the mark in the picture and wouldn't go above 80c and obviously limiter kicked in earlier.

I put a genuine renault stat in and my gauge sits bang on that line in the picture and reads the correct temperatures (read live via obd) and pulls all the way to the limit.

my understanding is this is exactly where the needle should sit unless you have the 265 with different clocks in which case it should be bang in the middle.

 

Mines bang on the middle, i had mine done two years ago. Mine totally went thou, where the neddle would move up n down depending whether i was still or moving.

 

As far can tell the clocks are identical meaning they look identical, would be good to have confirmation, not sure why Reno would fit different gauges on mk lll range

 

easiest easy to find out is plug in something like torque and read the live data.

i can confirm 100% my stat is working and reaching temp and it sits on that line and not in the middle between the 2 lines.

I have the yellow gauges, I believe the 265 came with a dark gauge where the temp needle sits bang in the middle.

 

the other option is wait until you believe your car is showing up to temp and try floor it til the limiter kicks in...if it comes in early then your stats gone.

but ideally I'd get a £5 Bluetooth obd dongle and torque app and read the live data.

 

yeah that's basically it dude.

there's a few to choose from and quality varies so some work and some don't.

I've got lucky first time and I've been using my adapter for years now.

 

ahh you would need a WiFi adapter then I think and then search the app store for a similar app to torque

 

I've changed mine recently, sat slightly to the left like the first picture had no issues high up the rev range.

The new thermostat sits exactly where it was before. I didn't use a genuine Renault part, was a gates thermostat but that shouldn't matter.

 

Hi off topic but can i ask where you got the obd wifi dongle that works and a link if ebay?Also the fusion app is it the one for £9.99 on app store
cheers in advance

 

Changed mine a year or so ago,as temp needle was to left like above image plus used to move around a little random!
Once changed bang in the middle at normal running temp

 

Thanks bud for your help i`m going to order it now then get that app

 

agree, after thermo change ODB app (DashCommand) shows 85 when moving and 90 in slow traffic

 

Hi Guys,

I am a few months late to this thread, reading your comments I am pretty sure I have the same problem but a lot worse and now I am panicking. My coolant temperature stays at the first bar most of the time, occasionally goes up by a bit but never to the second bar if I am driving the car. I have a RS monitor and oil temp is either below 70 or if I am doing 80 on the motorway low 70's for the oil temp.

The wired thing is that when the car is stationary both the coolant and oil temp rise quickly, coolant on the second bar, oil temp about 92 degrees. I can then drive off normally within 5 mins it goes back to what's mentioned above.

I thought the limiter is directly affected by the oil temp so I deliberately sit there till it gets to 90 degrees then go and put my foot down but it still cuts in early. Think my situation is kinda bad.
Let me know what you guys think
Thanks

 

Not sure what you having a panic attack for, replace the sensor.....

 

Your stats knackard, when driving your radiators keeping the temp down due to probably a hole in the rubber seal of the stat or slow opening stat, when stationary, especially in traffic the radiator isnt as efficient so the temperature will go up but never to full. My stat went exactly the sam and there was a small bit of rubber missing out off the seal (2-3mm)

 

So I've found this thread searching for temp gauge info....

Here's my gauge. The fan does kick in and I've sat idling for 20minutes after a half hour drive and needle hasn't moved passed here.

If you've got original factory stat then change it anyway, buy reputable aftermarket item but not from reno

 

Mines the same never heard my fans come on
