Thermostat replacement on my engine.

I don't have enough room to take the back lower bolt to take the thermostat off. What else do I take off to give me enough room. I was told that the intake manifold. Could you give me step by step instructions
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
The thermostat housing is held on by 2 bolts. The back bolt could be either removed by using a universal type of extension and tool on your ratchet, or removing the intake manifold to gain access to the bolt location. The intake seals will need to be replaced if you take off the manifold to prevent any vacuum leaks. If you need further assistance with your thermostat, then seek out a professional, such as one from Your Mechanic, to help you.

The primary thermostat is located on the front of the water plenum in the thermostat housing/coolant inlet. The secondary thermostat is located in the cylinder head under the water plenum.
Notes: Temp 194F, Engine Coolant Thermostat Housing Assembly.
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.
The average cost for a Chrysler 200 Thermostat Replacement is between $278 and $329. Labor costs are estimated between $195 and $246 while parts are priced between $83 and $83.
The ambient temperature sensor (switch) is located either behind the front grille or in the front bumper.
The most common cause for P0128 is the engine coolant thermostat is stuck open.
Notes: 203° F, Engine Coolant Thermostat.
The engine coolant temperature runs at 195° to 210° depending on driving conditions.
Locating the thermostat

In most cars the thermostat is placed under a housing near the water pump on the cylinder head ; the housing is connected directly to the top radiator hose . In a few cars the thermostat is housed near the bottom hose. Test the thermostat quickly by starting the engine from cold.

It is often located somewhere neutral, like the hallway, but it can often be in the main living room of the house, where occupants spend most of their time.
Most cars have two thermostats, but the number can vary depending on the car. Typically, with two thermostats, one is connected to your car`s AC system and one to the engine cooling system. The thermostats help circulate coolant either through your car`s engine or AC system, along with other intricate parts.
Most, if not all, large diesel engines found in trucks and farm equipment employ a dual thermostat system.

I have a 2010 camry. I just recently replaced the engine with a 2014 camry engine. Now I have Four engine lights on. I replaced on
ANSWER : If you swapped the engine from a vehicle that is 4 years newer than the car is then you are going to have electrical and sensor incompatibilities that may not be able to be fixed by just a few sensor replacements. There were many changes in computer and emission related items between 2010 and 2014 engines. I would recommend having a mechanic like one from YourMechanic come to you and compare the two engines to isolate the possible differences and see if the problem can be fixed.

The thermostat has been replaced in my car twice in six months because the Service Engine Light keeps coming on
ANSWER : The thermostats on this engine have an electrical heater element intended to help the engine warm up faster. Many thermostat housings for this engine are plastic – from different suppliers. The plastic housings tend to leak around the heater wire plug, and corrode. Engine management "sees" the bad connection from corrosion to the thermostat heater as a failure, setting a problem code for ’replace the thermostat’.

Replace the thermostat with one with a metal housing, and the problem should go away. I would recommend having a thermostat replacement completed by a mobile, professional mechanic, such as one from YourMechanic, to diagnose this problem, get an accurate assessment of damage and cost estimate for repairs.

Mechanics replaced water pump but did not replace the thermostat. Engine overheated and blew the head gasket? 2010 Jeep Compass
ANSWER : Hello – this is a judgement call. It is common practice, but not a "standard", to replace the thermostat when replacing the water pump. This is mainly due to access to both easily when replacing either one, and the relatively low cost of a thermostat. Thermostats do not have "wearing" items like the bearings in a water pump, and can outlast a water pump. They can, and do, however, fail unpredictably (close down tight) – sometimes. I have experienced this personally. I encourage my friends, relatives, students, and customers to replace both when repairing either – save the labor cost of a 2nd repair, and the somewhat unusual cost you have sadly experienced.

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.

How do you replace the rear & side engine mounts without lifting out the engine? & how do you lift the engine out?
ANSWER : Hi…thank you for your questions. If required in the application, a portable engine support bar is used to support an engine during mount replacement. The support bar has lifting capability as well so that the mount can be unloaded and removed. If a particular repair application requires a "crane" (complete engine removal for instance), such are portable these days in any event. With regard to the exhaust system repair, mechanics use ramps to gain access. Six ton portable jack stands will safely support a car two feet into the air which provides more than enough access to repair or replace any exhaust system component. If you desire replacement of the mounts, please refer to YourMechanic’s motor mount replacement service page. For exhaust leaks, please use the exhaust system inspection/repair page page. Once on each of those service pages, if you click on "Get a Quote" and enter your vehicle information (year, make, model) you can obtain cost info and schedule the service. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Hey Allen. I just rebuilt (?) the engine on my 06 Acura TL. Now the engine line went on. They told me the engine? can blow up if I
ANSWER : Hi there. I think it may be a good idea to find a new mechanic. Fortunately, our mobile mechanics are able to complete most diagnostic inspections and complete a lot of repairs services at your location, and on your schedule. In what you are describing above, the current issue seems to be with your EVAP system, which is designed to relieve pressure in the fuel tank and also collect harmful vapors before they escape into the air. Now, in regards to the car "blowing up"; that’s a bit dramatic, but it is important to have your issues repaired if it’s related to the EVAP system. Here is what I would recommend. Set up an appointment to have one of our mobile mechanics come to your location to complete a check engine light inspection – (click here to set up an appointment). This will allow them to download the stored error codes that cause the light to illuminate and determine what parts need repair or replacement. Then, they’ll be better prepared to provide you with a repair estimate and complete the repairs in most cases for you.

engine light on for thermostat or temp sensor, EVIC falsely states engine hot due to bad thermostat, also service throttle control
ANSWER : Hello. From what you describe it would appear that your vehicle may be experiencing more than one issue. It is indeed true that the thermostat and coolant sensors are built into a housing, which will require replacement of the entire housing to replace the thermostat. The sensors can, however, be removed and reused. If there is a message displayed that the engine is overheating then that could signify that the coolant temperature sensor is bad, or that the engine is actually overheating, perhaps due to a stuck thermostat. Removing the thermostat does not require removal of the cylinder head, however it does require a few components be removed in order to access the housing. If there is a message also being displayed for the throttle control system, then it is likely that the computer has detected an issue that needs to be addressed. Perhaps a fault with the throttle body unit or circuit. As it appears that your vehicle may be experiencing more than one issue, I would recommend having a professional technician, such as one from YourMechanic, visit your location, to diagnose what may be causing the issues.

I have a 96 Ford ranger with cel p0340 I have recently done a timing belt, engine runs great replaced cmp sensor cel still on
ANSWER : Hi There,
This may happen for a couple of reasons. First, check to be sure that the connections to the sensor are clean and not faulty or broken. Secondly, check to be sure you replaced the correct sensor as there are two camshaft position sensors in some applications.
