Will removing the thermostat have any impact?

Removing the thermostat will have an impact, including: 1. Slow heating in winter; 2. Slow rise in water temperature, leading to increased fuel consumption; 3. Prolonged cold engine operation, resulting in faster machine wear; 4. Severe wear and tear on the engine. The thermostat operates based on the engine's water temperature. If the thermostat malfunctions and the valve fails to close, the coolant will continuously circulate in the large loop, potentially causing the engine's water temperature to drop too low. Solutions for a faulty thermostat include: 1. After starting the engine, check if there is water flow in the cooling radiator; 2. Inspect the radiator inlet pipe for water flow; 3. Monitor the water temperature gauge for any abnormal readings.

Removing the thermostat is no small matter. This little component plays a crucial role in quickly raising the coolant temperature to normal operating levels when the engine starts, then maintaining stable conditions. Without it, the engine may remain in a cold state for extended periods—especially in winter, taking forever to warm up while fuel consumption skyrockets. Conversely, in summer traffic jams, temperatures could spiral out of control, causing the fan to run nonstop, risking overheating and damage like blown head gaskets. I learned this the hard way with an old car: to save a few bucks on repairs, I removed it, only to face erratic temperature gauge readings within a few hundred kilometers, ending with costly engine part replacements. Long-term effects? Inadequate lubrication accelerates wear, shortening engine life. My advice: don’t remove it. Get a new one installed properly at a reputable shop, and regularly inspect the cooling system to dodge these headaches.

Let me share a lesson learned the hard way. Once, my car had a minor issue, and to save trouble, I removed the thermostat, thinking it was just a small part and wouldn't matter. The result? Fuel consumption skyrocketed—previously, a full tank could last 500 kilometers, but now it barely made it to 450. Plus, the cabin temperature always felt off—slow to warm up in winter and delayed cooling in summer. Later, my mechanic friend explained that the thermostat helps the engine warm up quickly and maintain efficiency. Without it, the entire cooling system goes haywire: excessive engine wear in cold conditions, ineffective fan operation in heat, and risks of leaks or burst hoses. The most frustrating part? Short city drives felt fine, but on the highway, problems emerged—sudden red alerts on the temperature gauge were downright terrifying. Since then, I've dutifully installed a new one—small cost for big peace of mind. DIY isn't always the answer; sometimes, professional know-how is key.

Remove the thermostat? Definitely has consequences. Simply put, the thermostat acts as a switch controlling coolant circulation to help the engine reach optimal operating temperature faster. Without it, the engine warms up too slowly when cold - thick oil provides inadequate lubrication, accelerating component wear. Once heated, temperature becomes uncontrollable - even with fans running at full speed, overheating risks remain. Having driven in northern regions for years, I've seen many cases: vehicles without thermostats take over ten minutes to produce heat in winter, suffer skyrocketing fuel consumption, and accumulate carbon deposits inside the engine. Especially during long trips, sudden breakdowns due to uncontrolled coolant temperature pose real dangers. Recommend replacing it promptly - penny wise and pound foolish. During routine maintenance, always check the coolant temperature sensor to ensure proper system operation.
