Warming Up Temperature Gauge

[wahid hussian]

Hi all

Has anyone experienced the temperature gauge taking long to warm up I mean its not that cold here in Birmingham there's no problems with the car the heaters work fine its just that the temperature needle sits at the 3rd or 4th mark for a long time and when it does get to the middle if I put the heaters full it slowly comes down again

Is this normal or am i going nuts lol

Thanks guys

may be a stuck/damaged thermostat, allowing too much water to pass into the radiator and be cooled.

Hi mate thanks for reply how could I check for thermostat

[ColinBarber]

only really by physical inspection and at that point you may as well just replace it. Here is a previous post I found:

Hi all update

I've got the thermostat changed and water pump and timing belt done but it warms up ok but when put the heaters on it slowly goes down? Fans are working too can anyone shed some light on this

I also did do the reset

Have you had it properly checked out,the temperature gauge normally takes no longer than a few minutes to get to just under the half way mark,and it shouldn't drop when you have the heaters on - would still say its some sort of thermostat related issue.

Thanks for the reply mate
I did ask the guy who worked on the car for the timing belt he did say the new thermostat would sort it out?

it does warm up quickly and If i don't put the heaters full it would stay in the middle so I just put the heaters on auto and leave the temp set to about 22

The fans do work when it overheats

Thanks
