On the thermostat housing on a 2013 Journey, which way does the gasket end seal to? Does it seal to the part connected to the hose?

I replaced my upper and lower thermostats on my truck and it stopped the leak but now it's overheating. I put the not gasket end into the block for the lower and the not gasket end inside the housing. I think that maybe the upper thermostat might be backwards. Not sure tho. How do I know for sure

My car has 69000 miles.
My car has an automatic transmission.

Experienced mechanics share their insights in answering this question :
Installing a thermostat upside down will cause the engine to overheat. Although not impossible, the thermostat will fit better one direction than the other. The coiled or spring loaded end needs to go into the engine block. The end with the "seal" goes into the thermostat housing.

Think about the thermostat opening up when more coolant is needed, and put the moving end in the engine block. If you are sure the thermostat is installed properly, and that the unit you put in has not failed ("new" parts do come faulty sometimes), then you should look to your water pump next. The symptoms from these two components’ failure are very similar.

To avoid any unnecessary repairs, consider YourMechanic, as one of our mobile technicians can come to your location to diagnose the overheating issue and fix it accordingly. Best of luck.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

The most common reasons a Dodge Journey is overheating are a coolant leak (water pump, radiator, hose etc.), the radiator fan, or a failed thermostat.
Error code P0128 indicates that your engine coolant temperature is below the thermostat regulating temperature. This means that your Engine Control Module (ECM) or Powertrain Control Module (PCM) has recognized that your engine is running cooler than it`s supposed to.
Water outlet and thermostat gaskets can be installed with the striping facing either direction, as long as there no directional indicators.
Leaking Cooling System: Leaks are the #1 reason a vehicle begins to overheat. Leaks in hoses, the radiator, water pump, thermostat housing, heater core, head gasket, freeze plugs and a few other things can all lead to problems with the vehicle`s cooling system.
Is it safe to drive with the P0128 code? The code will illuminate the check engine light, but you can still drive your car. It will not cause any hindrance or sudden shutting down of the vehicle. The only problem you`ll notice is the temperature gauge not reaching the optimal levels.
Code P0420 indicates that the catalytic converter is not functioning efficiently, therefore increasing the output of harmful pollutants by the vehicle.
The AC sensor on your thermostat is located near the evaporator coils. Indoor air moving toward the return vents passes by the sensor and coils. In turn, the sensor reads the temperature and checks if it matches what you`ve set on the thermostat.
Notes: 203 °F (95 °C), Engine Coolant Thermostat. OEM recommended temperature.
Coolant/antifreeze is added to a vehicle`s cooling system, which circulates the fluid throughout the engine and radiator to prevent overheating. If your vehicle`s cooling system is functioning properly, it will effectively reduce the heat produced by the engine and keep everything running smoothly.
General description. The engine coolant temperature sensor is temperature-variable resistor, which usually has a negative temperature coefficient. It is a two-wire thermistor immersed in coolant and measures its temperature.
Depending on the root cause of the issue, the costs of fixing the code P0128 will most likely range from $150-$250.
If it is not flowing, wait until your engine warms up. The coolant should warm to the right temperature and begin to flow after 10 to 20 minutes. If it does not start to flow, but the temperature gauge on your dashboard rises, your thermostat is stuck closed.
If you unplug the coolant temperature sensor the PCM will see the lack of signal as a extremely low coolant temp. The PCM will set an injection rate that will be excessively rich.
A P0420 code is set when the upstream sensor and the downstream oxygen sensor sense the catalytic converter is not doing its job. Basically, the amount of oxygen going into the converter is not being burned, and it detects it through the downstream sensor.
The p0420 code means that the catalytic converter is below threshold and is not functioning correctly. This code comes up when the catalytic converter can no longer burn off any fuel in the exhaust system.
If your thermostat fails, the engine will not operate within its ideal temperature range. In turn, this will affect the -performance of your vehicle.
Running an engine without the thermostat can cause the engine to overheat due to the coolant passes through the engine too fast and will not let the coolant absorb the heat from the engine.
The water pump moves the coolant through the system and the thermostat regulates this flow to maintain operating temperature. If the water pump has failed, the coolant will not flow through the system so the temperature will rise quickly and the heat will be concentrated on the engine.
The most common signs of a broken thermostat are: The thermostat display is off or is non-responsive when you try to adjust it. The display on the digital screen is faded or incomplete. The furnace or air conditioner does not respond when you adjust your thermostat.
No power: If the thermostat isn`t working at all, there could be a power issue. Try checking the circuit breaker box or replacing the batteries. Bad wiring: The thermostat may be unresponsive if the wiring has gone bad. Remove the cover and check inside for loose, detached, or corroded wires.
Blown head gaskets can happen when an engine severely overheats due to a faulty thermostat, clogged radiator, leaking water pump, radiator, radiator hose or heater hoses or when the coolant in the cooling system is not changed per the O.E.M.`s scheduled maintenance.
The ECT sensor is often located on the engine block, usually near the thermostat housing. On some engines, it may be located on the intake manifold. The sensor measures the temperature of the coolant and sends a signal to the computer.
Normal coolant temperature will be around 195 to 220 Fahrenheit (approx 90°C) and anything above or below this can start causing problems.
Once the engine coolant reaches the design temperature, usually around 195 degrees, the valve will open and close as you drive in order to maintain a coolant temperature typically between 195 to 225 degrees Fahrenheit.

Rear Axle Seal Replacement – What type seal?
ANSWER : Hi there, thanks for writing in. I recommend buy the Toyota OEM part. Although we could go into high detail as to the precise technical differences amongst the various and competing aftermarket seals you are describing, such will not change the conclusion at all. Generally speaking, aftermarket parts are NOT as good as the factory OEM parts. Large car manufacturers spend hundreds of millions of dollars, indeed billions, developing the technologies used in these vehicles and ALL of the parts are extraordinarily carefully engineered to fit very precisely and perform specific functions. In the aftermarket, they try to duplicate that, but more often than not, it does not work. Toyota OEM quality in particular is not duplicated well, if not at all, in the aftermarket.

Common ways Oil Filter Housing Cracks
ANSWER : If the crack in the housing is in the plastic part, that can be written off to normal wear and tear. The plastic filter holder gets brittle and cracks easily. Most shops keep them on hand in case this happens during an oil change. If the aluminum housing is cracked, It’s possible that could happen during a service operation. If your car uses the oil cooler that is attached to the filter housing, a crack could indeed develop it the bolts are installed incorrectly. It would be difficult to prove, however. If you are to have any hope of getting compensation you would have to have the dealer do the repair and rely on their good will as to whether they are willing too admit fault. Pursuing it any further would mean working through Mercedes Customer Service. It could end up being a big hassle with little return. If you just want to get it fixed you can Contact Your Mechanic to have a technician come to your home or office and fix your oil leak for you.

what is the name of the opposite end of the thermostat housing where the thermostat seats?
ANSWER : Hi there. Without seeing what you are referring to, it’s difficult to tell you exactly which part it might be that you need to replace. It’s probably a better idea for you to review this website for replacement cooling system parts and components for your 1995 Isuzu Rodeo. Hopefully you’ll be able to find the part you need.

Gas tank seal from the filler neck hose.
ANSWER : The nozzle I believe your are mentioning is the anti-siphon and roll-over check valve. It does not require a perfect seal to the tank. The rubber filler hose slides over it, sealing in fuel vapors. I hope this helps. Put it back together the way it came apart and it should be fine.

What’s the name of this hose nobody seems to know or mention even in Google?
ANSWER : The hose you are referring to would be the bypass hose. It is very possible that plymouth may have a different name for the hose but the typical name for this hose is the bypass hose.

This hose allows coolant to bypass the thermostat to keep the circulation of coolant going through the engine before it has reached operating temperature.

Depending on how the hose connects to the vehicle, you may be able to just get a piece of bulk hose that is the same size and length as the old hose and just use that.

If you need assistance with replacing it, have one of our mobile technicians come to you to diagnose any issues firsthand and replace your bypass hose as necessary.

Leaking air from part directly next to where the upper radiator hose connects to the fail safe and engine, wondering what part is?
ANSWER : I haven’t seen one of those old Dodges in a long time. I wish I had a little better description of what you’re asking about. I’m going to go out on a limb here and say that you are asking about the A/C compressor. That would be belt driven with hoses coming out of it.

Does the replacement of a thermostat include replacing the housing? I was told I needed to replace the thermostat housing.
ANSWER : Hi, thanks for writing in. The thermostat housing and the thermostat itself are two different components and do not necessarily need to be replaced together or at the same time. The housing is just a piece that covers the thermostat that also has an opening for a radiator hose which is where the water enters and exits the motor. The housing may need to be replaced at times if it is cracked or leaks severely, however they are indeed two different and distinct pieces.

Hope this helps and best of luck.
