![]() ![]() Break the 10-millimeter bolts free that are on both sides. You can't move this bracket too far because it's on these wires, but you can move it over just enough. I'm going to remove those first using a 10-millimeter socket and ratchet the right way. These are all 10-millimeter bolts, so these two are just holding this bracket on. I'm just going to put it down out of the way. I'm using some slip-joint pliers to prop on the locks, move the clamp down, and loosen this hose up. We're just doing it to give you a better view. We're going to move the upper radiator hose out of the way so you can see what we're doing better, but you shouldn't have to actually remove it to do the thermostat. There's two bolts that hold it in and then two bolts on this bracket here that hold the O2 sensor wires. ![]() We're going to remove the thermostat, which is located here in the lower radiator hose. Now you're ready to refill the radiator and bleed the system. Just use your hand to tighten it because you don't want to overtighten it. Don't forget to do this before your refill with coolant so it's ready and in place. With this drained, I will reinstall the plug. If you go up top and you open the radiator cap, it will drain even faster. Just make sure that when you loosen it, you've got your drain pan or bucket ready because it will come pouring out. If this is too tight to take off with your fingers, you can use a pair of pliers to loosen it. There's a nice opening in this plastic shield. The radiator drain is located right here. You'll have to raise and support the vehicle so you can at least get to the drain at the front of the vehicle, so at minimum, you'll want to raise the front. That puts the hood almost vertically and gives you a lot more space to work. You can actually lift the hood up further and push the prop rod into this opening here. If you need to work on the engine, you don't want to be hitting your head. There are two spots you can put the prop rod. We’ve been selling auto parts for over 30 years! To open up the hood, pull the release. If so, the car’s safe to be back on the road.Hi, I’m Mike from 1A Auto. Check if the temperature gauge is reading fine.Tighten the radiator cap and add the coolant back or replace it if it’s old.Replace the hose if it’s leaking or worn out. Clean and reassemble the radiator hose, hose clamp, and thermostat housing.Remove the old thermostat and install the new thermostat.Test the new thermostat by placing it in a bucket of boiling water.Ensure the new thermostat and gasket are similar to that of the old thermostat. Remove the radiator hose with the hose clamp and take apart the thermostat housing and gasket.Find the thermostat by locating the radiator hose.Drain enough to bring the coolant level below the thermostat housing. Drain the engine coolant (antifreeze) through the radiator cap.Ensure the vehicle has cooled down to prevent burns.Here’s a general guideline on how a mechanic would perform a thermostat replacement: So, it’s best to leave the replacement to a professional mechanic rather than attempt a DIY repair. Thermostat replacement requires a fair bit of knowledge and experience to ensure that the components and the cooling system work efficiently. This can include a radiator hose replacement, water heater installation, or air conditioner repair (AC repair). Īs a safety measure, you could replace your existing thermostat when your vehicle’s cooling system components are serviced. So, most mechanics recommend a thermostat replacement after 10 years. Here are the different types available for your car:Ī car thermostat does eventually wear down and fail. Vehicle thermostats may be either mechanical or digital. What Are The Different Types of Thermostats? This keeps the engine at an optimal temperature (between 195☏ to 225☏), preventing overheating. When the engine hits a certain temperature (usually around 195☏), the valve opens, allowing the radiator to cool the liquid coolant. This, in turn, promotes efficient fuel use and reduces engine deposits. It traps the engine heat, helping it quickly heat up to the right temperature. When you start your car, the thermostat valve is closed, preventing the coolant flow from reaching the radiator and cooling the engine. It’s an important part of your vehicle’s cooling or heating system or HVAC system, helping regulate the temperature setting of the vehicle. The thermostat helps keep your engine running at the right temperature. Here are quick answers to four questions about thermostats and their replacement: 1. ![]()
