I am Suzuki Liana RXI 2009 owner. During the starting days of winters, I realized that when I turn the heater ON, the temperature gauge starts to go down a little. I found that there is no Thermostat valve. Ultimately I purchased the Thermostat valve and properly verified that the valve is in working condition by boiling it in full of water pot the valve gets opened. However, when I installed it in the vehicle it was not working. The temperature gauge turns to normal and the one pipe was very hot and the other was still cool after some more time the radiator fan turned ON and then stop. The heater problem was solved but the valve was not doing its work. Can any buddy suggest to me what should I do?
its working. don't worry.the process you described here is the sign that thermo valve is working great.
Why do you suspect its not working?
what u want the valve to do.
as u described, it is working. What ur temp needle says now? does it reaches half and stays in middle or not?
Thank you for the reply. I mean that if the engine reaches to the optimum temperature than the valve should be open and to identify this the lower pipe needs to get hot but in my case the the engine reaches to the maximum temperature but the lower pipes always remain cool.
your engine temperature gauge reached max H? - and your lower radiator pipe is cold?
or your engine temperature gauge is in middle and lower hose is slightly colder than top one?
are they hard with pressure?
Do you have automatic fan? Or direct fan?
Also have you checked with radiator cap open if the water flows or not with valve opened or closed
you wont be able to notice flow in a liana radiator due to the way its plumbed, however one can use a tight fit funnel to check the level if it goes down on accelerating the engine.
Location of thermostat valve is ???
It is located adjacent to the water body. You have to remove CNG injectors, Throttle Body and Intake manifold to get access to it sadly.
During Rain , missing related to this valve or not???
Nope. Missing during rain might be due to water getting to your crankshaft sensor plug or wire as it is located very close to the bottom of engine. Get that checked and also check your plugs, coils and coil leads.
That plug is watertight, it will only allow water in if its seal is damaged.
