Is this thermostat valve suitable for my Civic

[xhaikh1]

Asalam u alikum guys
I have the Honda Civic 2003 exi manual transmission, its radiator fan is automatic but there is no thermostat valve present in the car so car take time to reach the optimum temperature to run. So i got the valve from my previous car corolla but for some reasons I did not installed that and now you guys tell me that is it suitable for my car also or i have to purchase the other one i am attaching the pictures of it i already checked in hot water also it works perfectly.

And my car fuel consumption is too high also which is around 7.5 kmpl with AC in city and 12 to 12.5kmpl on highway with AC. I already have changed lots of things such as following

Plugs
Oil,fuel and air filters
Oil 5w30 shell
Used high-octane also
Changed injectors also kabli one
Tappet adjusted
Throttle cleaned
Tyres are 185/65/15R with alloys
Alignment and suspension done

But no luck still

Wailaikum Assalam
D series thermostat start opening at 76-80 C and has 8mm lift height at 90 C (fully open state)
One you got has 82 written on it means it start opening late at 82 C, don't know about lift height.

This wont fit either,

Go buy a new one for a honda civic and its rubber gasket too.

Begins to open @76-80*C
Fully open @90*C
Lift @full open 8.0 mm

how come wothout thermostat fan is auto pros and cons of it and how it works?

[hasankhurshid29]

Without thermostat, the car will take longer to come to operating temperature but eventually it will come and then you need fan to turn on so to avoid overheating.
There are no pros of not using Thermostat, only cons
Like it will take longer for the car to come into operating temperature...
Most bad combination is fan direct and thermostat removed. That engine will never reach operating temperature

how to check if the vehivle has no thermostat?

[hasankhurshid29]

Remove the cover on the thermostat housing
I am talking about civic
In other cars you maybe able to see by removing the radiator hose or you have to remove the thermostat flange.

If you want to check without removing, you can note how much time it takes to reach optimum temperature. Ideally it shouldn't take more than 10 minutes in our weather.

[Xulfiqar]

your car should come upto temperature (half point on gauge) within a few minutes maximum. To physically check it, drain a little coolant from radiator and remove top hose pipe at engine side and use a small torch to see inside. You will see the thermostat.
