I will assume that you are speaking of the thermostat when you say "valve".

In that case removing the thermostat can cause boil over in long run conditions in elevated temperatures as it has no way to stop or divert the coolant flow to cool the coolant an reintroduce it back to the cooling system. Also unless you plan to run the car longer than 45 minutes before you drive; your windshield defogger/defroster will not work enough to clear the window on rainy days.

50% to 60% as you describe; on the temp indicator I would consider normal operation.

~ Hope this was of help and answered your questions

Which fuse is for the instrument panel back lighting?


Does the radio play ? Are any other back lighting components not lighting ? Does the HVAC control panel light up ? You probably need new radio !
The second interior lighting group includes lamps which may be dimmed. This group may use a combination of vacuum fluorescent (VF) illumination, LED illumination and incandescent lamps.
When the ignition switch is turned to the RUN position, the radio VF display turns ON at maximum brightness. When the park lamps are ON, all incandescent and LED back lighting turn ON at the dimming level indicated by the instrument panel (I/P) dimmer switch. At the same time all VF displays dim to match the indicated dimming level. The panel dimmer switch potentiometer is an input to the body control module (BCM). When the driver selects a dimming setting by moving the I/P dimming switch potentiometer, all incandescent back lighting lamps are provided with a specific voltage. When the I/P dimmer switch is moved from MIN to MAX, all VF displays, as well as all incandescent back lighting respond from minimum intensity to maximum brightness in response to the I/P dimmer switch.

I have 2008 PT Cruiser; getting P0128 code; I've changed thermostat & temperature sensor; I have to fill the anti-freeze container every 2 weeks; temperature hand will not always be at half way point. ...


This means that the engine's PCM detected that the engine has not reached the required temperature level within a specified amount of time after starting the engine. The intent of the P0128 code is to indicate a faulty thermostat. In determining the engine did not reach a "normal" temperature, it takes into account the length of time the vehicle has been running, the intake air temperature (IAT) sensor reading, the engine coolant temperature (ECT) sensor reading, and the speed of the vehicle.
A code P0128 may mean that one or more of the following has happened:
  • Low engine coolant level
  • Leaking or stuck open thermostat
  • Faulty cooling fan (running too much)
  • Faulty coolant temperature (ECT) sensor
  • Faulty intake air temperature (IAT) sensor
Past experience indicates that the most likely solution is to replace the thermostat. However here are some suggestions on troubleshooting and repairing a P0128 OBD-II code:
  • Verify coolant strength & level
  • Verify proper cooling fan operation (check if it's running more than it should). Replace if necessary.
  • Verify proper engine coolant temperature (ECT) sensor operation, replace if necessary.
  • Verify proper intake air temperature (IAT) sensor operation, replace if necessary.
  • If the above items check out good, replace the thermostat
you have all ready replaced the thermostat with the proper temperature opening thermostat(hopefully) and coolant sensor, you say you have to refill the coolant every 2 weeks this indicates that you either have a coolant leak that needs to be checked out and repaired or you are burning coolant which indicates a possible head gasket problem which will have to be checked. a low coolant level will set this code as there is not enough coolant in the engine to get the engine to operating temperature and stay there. these last suggestions is where I would start to look.

When do I add coolant


there is a tube or hose running from the radiator to a plastic bottle, the bottle has two lines on it, maximum and minimum levels, when the coolant level is lower than the minimum line you can fill it to the max line. one note of caution: if the car is hot or cold this can change the level so check it when you first go out in the morning to start it.

How do i reset check brakes


Pad removal procedure
Inspect the fluid level in the brake master cylinder reservoir.
If the brake fluid level is midway between the maximum-full point and the minimum allowable level, no brake fluid needs to be removed from the reservoir before proceeding.
If the brake fluid level is higher than midway between the maximum-full point and the minimum allowable level, remove brake fluid to the midway point before proceeding.
Raise and support the vehicle.
Remove the tire and wheel assembly.
Remove the caliper from the mounting bracket and support the caliper. Notice: Support the brake caliper with heavy mechanic's wire, or equivalent, whenever it is separated from it's mount and the hydraulic flexible brake hose is still connected. Failure to support the caliper in this manner will cause the flexible brake hose to bear the weight of the caliper, which may cause damage to the brake hose and in turn may cause a brake fluid leak. DO NOT disconnect the hydraulic brake flexible hose from the caliper.
Remove the brake pads from the brake caliper bracket.
Remove the brake pad retainers from the brake caliper bracket.

Installation Procedure

Important: Use denatured alcohol to clean the outside surface of caliper boot before installing new brake pads.

Use a C-clamp in order to compress the piston to the bottom of the caliper bore. Use the old brake pad, a metal plate or a wooden block across the face of the piston in order to protect the piston and the caliper boot. Important: Use a small flat-bladed tool and lift the inner edge caliper boot next to the piston to release any trapped air.
Ensure that the piston boot is below the level of the piston face.

Then the minimum engine oil level has been reached. You should check the engine oil level on the dipstick, and fill up with new oil until maximum level mark on the dipstick, but not above the max. oil mark!
Then everything will be all right, and oil yellow light will turn off.

92 nissan maxima-brake light on dashboard


newmomtobaby: the brake light coming on is probably from the fluid level in the brake master cylinder being below minimum level. It has a sensor, which is actually a float which senses the level in the master cylinder. Once it drops to a predetermined point, it will make the light come on.
If you look in the engine compartment on the driver's side close to the fire wall, you will see a plastic reservoir usually with a black cap. On the side of the reservoir you will see the words minimum and maximum or just min and max, with lines near them.
If you remove the cap, (some unscrew counter clockwise) others you just rotate 90 degrees counter clockwise and lift the cap off.
Get "DOT 3" brake fluid and pour it into the reservoir until it reaches the maximum line.
Caution: if you spill brake fluid on the paint, water will neutralize the fluid so it won't attack the paint!
Another thing which can cause the light to come on, is the parking brake not being in a fully released position.
The last item is a proportioning valve in the braking system, IF the car doesn't have ABS.
Hopefully I have answered your question.
You should get you brakes inspected for wear. As the pads wear, the fluid level will drop in the master cylinder because it is displacing the material worn off from the pads.
Many people don't use their parking brakes consequently the parking brake will become ineffective.
Good luck.
let me know how I did if I resolver your problem.

My Brake Light on My dashboard is coming on when I brake, but the fluid is above the minimum level, and I had my brakes looked at less than a year ago. the dashboard brake light comes on intermittently...


You hava very common issue.
The brake fluid contracts when it is cold. The level may be "above the minimum", but being there allows the sensor to activate when it is cold, due to the contraction aspect of the brake fluid...
Add 1 ounce of brake fluid, and you problem will disappear.
A FixYa rating for my assistance would be greatly appreciated.
