What is the thermostat temperature for a lincoln navigator 2004?
OEM opening temp is 195°
WHY DID MY LINCOLN LS OVERHEATED?
Lincoln LS v8 is a royal pain to bleed air from the system. The cooling system has two seperate fill locations, the expansion tank and a cap above the thermostat, and an air bleeder valve next to the expansion tank. Remove both caps, fill the engine to the top of the thermostat housing and reinstall engine cap. Fill the expansion tank to between the min/max lines. Start the engine with the heat set to 90 deg F (driver and passenger). Open the air bleed valve. Increase the rpm to 2000-2500. Close the air bleed valve after a solid stream of coolant begins to flow. Allow engine to get to full operating temperature and verify eng temp stays within "normal" range. If engine begins to overheat, repeat above steps. When done, verify coolant at proper level in expansion tank and you should be all set.
What happens when you overfill the radiator reservoir tank?
Not much will happen in most cars. As the liquid heats it will expand & run out the overflow tube. This might happen a few times but sooner or later it will get down to the proper level.Keep an eye on the coolant level that too much doesn't overflow out. If it gets low when the engine is cool add a wee bit to bring it to the proper level.And remember: be sure to read the instructions carefully … some 'antifreeze' is premixed, while some brands come full strength. The unmixed coolant doesn't absorb & transfer heat as well as properly mixed coolant. If your coolant is full strength mix water with the coolant in the amount shown on the jug's instructions panel. If already pre-mixed don't dilute further.Finally, if you're putting new coolant in the cooling system don't forget to open the heater control to fully open when you drain the old coolant, then leave it open when adding the new coolant.. The heater core inside the cabin is like a second radiator … heated coolant flows from the engine to the heater core & transfers heat from the coolant into the cabin. Failing to open the heater control can cause air to enter the cooling system which can result in engine overheating, possibly causing a blown head gasket or even a cracked block or head.
What are the main causes of high oil pressure?
Oil pressure in a car is measured as the resistance to flow between the oil pump in the oil pan and the bearings in the crankshaft. If it is actually too high, it means you are not getting enough oil through the bearings to keep your engine from self destructing.The higher your rpm, the higher your oil pressure, up to the point where an extra valve detours the excess oil back to the oil pan to recirculate. Typically, at idle you will have 10 to 15 psi, with 30 to 40 psi at driving speeds.The colder your engine, the higher your oil pressure, as the oil is still much thicker than it will be at operating temperatures. Typically, on startup, you will have 40 to 60 psi, which will drop to ranges listed above once the engine heats up.A high oil pressure reading on your gauge means:The oil is too viscous (thick). Most cars today are designed for 0W-20 to 5W-30 viscosity. If you are using 10W-40, 20W-50 or something like that, you will have high oil pressure and high wear.Your filter bypass valve on the filter or in the block is stuck closed, and the oil is too thick or dirty to pass through the filter media, trying to go through the bypass valve.If the high pressure is at high rpm, it may be the secondary bypass valve I mentioned at the beginning.Clogged oil passages to the bearings from sludge.Your thermostat is missing or stuck open, not letting the engine heat up.Your gauge is broken. Check it with a manual gauge.
Why is my car shaking and the check engine light flashing?
A shaking vehicle AND flashing MIL ("check engine light") sound like the vehicle is misfiring on at least one cylinder. As @Anna Nguyen, @Brendan Sinclair, @Antoun Nabhan and others have said, it could be an ignition related problem. It could also be fuel-related. If one or more fuel injectors are clogged or dead, that would also cause a misfire in the affected cylinder(s). These are relatively cheap/easy things to check and fix.Other causes (which could be more complicated and more expensive) to fix include contaminated fuel, a bent intake or exhaust valve, a broken valve spring, a damaged piston/connecting rod, and on and on.I recommend getting a scan tool and checking the codes which are causing the MIL to light/flash and I also strongly recommend NOT driving the vehicle until the problem is fixed. If you continue to drive the vehicle as is, you will exacerbate the problem. Dumping unburned fuel into the exhaust due to a misfire will overheat and kill your catalytic converter. A more serious problem like a bent valve can eventually cause you to crater your engine (i.e.: completely destroy the engine).
Can you drive a car with a motor mount that needs to be fixed and how far?
As long as it’s not completely broken you should be able to drive it. You can test the motor mount, to see how bad it is before driving the vehicle. You’ll need an assistant.Open the hood of your vehicle.You need an assistant to watch and see how much the engine moves when you press on the accelerator with the brakes applied.Have your assistant stand to the side (not in front of the vehicle) and observe the engine while you do the following procedure.Start the vehicle.Make sure nobody is in front of you in case the brakes fail and the vehicle lurches forward.Engage the emergency break and hold your foot firmly on the brake pedal to prevent the vehicle from moving.Put the vehicle in DriveWithout letting up on the breaks, gently press on the accelerator to rev the engine slightly.If the engine moves just a few inches then the motor mount is bad but it’s probably still safe to drive it for a while longer.If the engine moves more than a few inches then it may not be a good idea to drive it at all. What you want to avoid is the situation where the engine is able to move far enough that it collides with the hood or other components in the engine compartment.
