Temp gauge

Tomster · Dec 11, 2020

Advice needed please......My temp gauge never goes higher than this(see pic). Does this mean that the car is never running at the correct temp?Would I benefit from the thermostat mod (bodge)? Would having the gauge go higher affect how the car runs?
Thanks everyone.

For the gauge to be that low, the engine probably isn't getting above 70°C, which is too cold.

So it'll need a replacement OE thermostat, or the top hose Renault 4/5 "bodged" stat, which works just fine.

How does not reaching temp affect the running? What does it affect?

Running wise at a lower temperature, the engine isn't affected too much. However the engine won't be as efficient, as it would be if it was at 80-90°C. This is even more of an issue if you have the FBH fitted, as it'll be firing all the time to warm the heater.
The heater won't be as hot as it can be, which is a massive issue, as heater performance is marginal anyway.

But check the actual engine temperature with diagnostics first, just in case the dash gauge is wrong !! .

Hi Nodge, temp only seems to get to about 62, should I fit thermostat bodge?
Do the other readings look ok?
Thanks for the help...

It's fit an OE thermostat which is £80, plus about 4 hours work, due to its location, or fit the top hose mod thermostat, which is about £10 plus 1/2 an hours work.
Both will do the job, but remember that the OE thermostat will fail again in another 2 to 3 years, whereas the top hose mod seems to have a longer life.
You decide.

The fuel rail is way to low for the high pressure rail, so I'm assuming it's the low rail pressure on that readout, which seems acceptable.

Cheers mate, went for the easy option, bit of a faff as I’m no mech but seems to be working. Gauge has never been this high since I’ve owned the car.

Hi mate, thanks for the advice.Went for the bodge option and all is good now ( gauge bang in centre). Could I just ask for a little more advice? I’ve been having this juddering issue when decelerating to a lower steady speed. Just noticed today when I started up engine after it was up to temp that I kind of got a judder which I could feel through the seat in park just ticking over . I have it a good Rev and it stopped and is now idling lovely. Any idea what this might be and if it could be the cause of the juddering. Sorry to be a pain but I’m kind of new to mechanics but loving the Hippo.
Cheers and all the best....
