Assalam-o-alakum Pak Wheelers. I hope my new blog published on PakWheels helps you guys out in taking all the right decisions for your car's cooling system.

Why Removing Your Car’s Thermostat Valve is a Really Bad Idea!

Don't forget to share the knowledge with everyone because sharing is caring.

Cheers!

Nice. But Brother u dont get Problems on the cylinder head gasket because of the thermostat. When the valve stocks close then u will as a result of the higher temperature of the engine. The biggest Problem is that the cylinders and pistonrings wear faster bcz the engine is running under lambda 1 means fat. The result of running under lambda 1 with a cold engine means that the patrol damages the oil film in the cylinder so the friction between cylinder and pistonrings is higher. An Aluminium Cylinderhead cant rust it is Aluminium. The Engine Block and other parts can rust inside and that stucks in the cylinderhead. And recommend 50 to 50 mixture? I think the production specification is the only recommendation u should do or do u recommend the driver in murree the same like a driver in multan?

Bad idea. Thermostat valve is the most important thing to control temperature . I try to explain . Their are four main components to control temperature . 1.Fan
2.thermostat vole.
3.radiator
4. Engine body.

Let's take an example of civic 2005 . engine's suitable temperature is 70 to 85 degree . Thermostat valve locates in between engine body and radiator. At the edge of thermostat valve joint switch for Fan is located. agar ap k pass koi thermostat volve Hu to apply os pa dakh sakty hain , cap walii side pa temperature mentioned hota ha, at which temperature it will be opened up. and allow flow of water to radiator.

Jab hum engine start karty hain . Engine temperature low hota ha. Thermostat valve os waqat qaam ni karta or water ko radiator ki Taraf flow karnay sa rook daita ha . When temperature crosses it's limit of 85 degree it allow the water to flow towards radiator. Thermostat valve k joint pa fan ka switch hota ha . Or wo fan ko on kar dait a ha . Kio k fan ka switch 75 degree pa on jata ha . Radiator ka pani engine ki Taraf flow kar jata ha . Engine ka temperature low Hu jata ha . Or thermostat valve close Hu jata ha .

If you remove the thermostat valve it's mean water will flow towards radiator without temperature control . Or you can sa engine complete cooling system has free flow of water. Which makes the complete system temperature same . Or is Tarah porra system jab take heat up na Hu 80 degree sa above fan ni on hota. with passage of time engine kazoo Hu jata ha .

Last bat agar valve nikalna ha tu hamesha fan direct honda chaya

The problems with the head gasket are primarily due to running water instead of coolant causing corrosion and weakening of the gasket material that makes it more susceptible to damage. Once weakened, it can blow anytime since metal plates then into flakes of rust that can no longer hold pressure and get torn apart. I've seen enough rusted out head gaskets over the years that fell apart like corn flakes when head was removed.

The block also gets damaged since water turns into carbonic acid overtime which can eat up any metal. Although aluminum resists corrosion but it can't do it forever in the presence of acid running around in the cooling system and stray electrical currents causing electrolysis reaction inside the cooling system. That's how you get radiator and heater core leakages overtime due to running water with no corrosion inhibitors in it.

Overheat caused by any combination of reasons including missing thermostat, leakage or wrong radiator cap just add to the problem. Overheat warps the threads of head bolts due to out of specs thermal expansion of the metal which presses the gasket to an extent that it develops a leak. This is also primarily the reason why replacing the head bolts upon a gasket change is always highly recommended but our genius mechanics always reuse old books because they are "Jeeenyaan" and "Japaaani". That's a disease common in our country.

Lastly, 50-50 mix is the world's most widely used proportion when it comes to pre-mixed coolants, unless you're driving your car inside a bubbling volcano or near the north pole where temperature is below - 30 degrees Celsius. That's not the case anywhere in Pakistan. If you live in an extraordinarily cold place such as Russia or Alaska, you can use arctic type 60—40 ethylene glycol mix (60% coolant and 40% water) that provides freeze protection upto - 52 degrees Celsius.

removing thermostat valve from engine cooling system is like removing a kidney from any mammal. apparently nothing seems wrong but the whole systems starts to deteriorate at unknown speed.

remove a kidney and use contaminated drinking water ( remove thermostat valve and use plain water in cooling system )

2 x 2 = ??

Safwan Bhai i give u answer per Paragraph for the clarity.

Primarily bcz of water? You have (depends on the thikness of the gasket) maybe 1.5mm. from the coolant side where water can attack the gasket and for the gasket it is no problem to handle that by a normal used engine the water is always circulating and heating up so it is not a primarily problem for the gasket there they can take it dont worry they are sealed there with special materials on the gasket bcz of that "problems" frm the manufacturers of the Gasket. When the gasket gets material weakness water can go thru this way and then the pressure frm cylinder side blows up the gasket. I never and no engine builder will recommend drive without coolant.

I also said the Block is getting corrosion so no need to talk abt that. But Brother electrolysis in the cooler frm electrical currents? We are talking here from something that runs/circulates. Did u ever saw an elektrolysis? It takes time when u dont have enough electrical power but maybe i read it wrong i cant imagine u are saying this to me. So i talked with an manufacturer of radiators and the main problems of todays radiators are that they are to thin. Before we can repair radiators but try it with todays. He said the problem is that the car producers want to buy them cheaper so...
And yes water in radiators is not gud

Thanks to god i never saw here a mechanic wich is taking the same bolts i never heard that before.

Ok for example vw says -25 or -35°C. Mercedes -30°C. Ferrari.. and so on. How u will do that when u just ad 50to50? When u change the coolant every 48 to 96months (recommend frm vw,audi,seat,skoda,porsche and so on) it is easy but not when u ad something. so we measure the coolant and ad what is needed.
For example i have only water in my coolant (what we both forbid people or dont recommend) than i see my water is a bit under the minimum level (we both know why - only water ) so i want to fill it up and i remember safwan bhai's word 50 to 50 means 1:1 so is it right?

Thanks for reading till here Bhai i think the heading words of the article r wrong choosen. And i highly recommend for our mechanics an "how to install an thermostat correctly". Allah Hafiz

Nice example for an Honda 2005. I just wonder that it is such a simple system.
For example an Audi of 2005 has two to three coolant temperature Sensors one in the small coolant circuit (thermostat closed) and one or two in the big circuit (thermostat open). The electrical resistance of the sensors is given to the ecu and the ecu gives the signal to the fan(s). The fan(s) work in three ways minimum middle an maximum power. the goal is to keep the temperature always at same level so the thermostat is always fully open.
In todays Cars (German Cars) we have minimum two thermostat's working on other celsius levels. And the fan has an electrical signal wich means Pulse width modulated.
