Blockage in system causing coolant not to circulate

Under the power steering pump. You will have to remove the pump first. Should only need an 8 mm wrench and a screwdriver to replace the sensor. Good luck.

See diagram below...Original diagram should be attached to the passenger strut tower... saailer I’m happy to help further over the phone at https://www.6ya.com/expert/david_6df67de3b14de867

When it dies, does it start right back up? Have you tested to see what it does not have when it dies? Is it loosing spark? Is it loosing fuel pressure?

You have a gremlin ! No , just kidding . No it's not the ignition switch ! The headlamps right an left have there own fuse in the under hood fuse box . LH HDLP - RH HDLP . Power direct to the head lamps an they ground through the headlamp switch when placed in high or low beams . Next time they come on wiggle the headlamp switch an see if they go out ! Does your vehicle have auto lights ? Day time running lamps ? The BCM - body control module controls Automatic lamp control ! Battery voltage is applied to the headlamp bulbs at all times. The headlamps are controlled by supplying the ground for the lamps through the turn/headlamp switch assembly or the body control module (BCM). When the turn/headlamp switch is in the ON position, the ground is supplied through CKT 150. The BCM controls the daytime running lamps (DRL). The system allows the headlamps to operate at a reduced intensity under the following conditions: ?€¢ The engine is running.

?€¢ The transaxle is not in the PARK position.

?€¢ The normal headlamps are turned OFF.

The BCM activates the system by grounding CKT 592. This action energizes the DRL relay. This condition allows a reduced voltage to flow to the headlamps. When the headlamp switch is turned to ON, the headlamps operate normally. The parking brake provides an input to the BCM. When the parking brake is engaged, the DRL remain disabled until the parking brake is disengaged.

This happened to me the sensor for emergency brake was bad so I disconnected the sensor

yes it is safe -your brakes will work normally only difference u will see is if u hit[stomp] on the brake hard will cause wheels to lock up[skid] check the sensors wiring ,connections and connection to clips the sensor is incorporated into the wheel hub but the wiring and clips connections are exposed which can get damaged or hit by road debris -if u remove the wheel will see wire running into back of rotor --to replace will have to replace the whole hub[wheel bearing] average price about $80 for part if diy

This could be caused bya vacuum leak and causing the engine to run lean. It could also be caused by a misfire. ( spark plug or wires )

40 lb-ft and sequence and then a final 90 degree turn on each bolt in sequence.

The reference I found was bolts to 40 lb-ft in sequence. I always like to reach the final torque value in 2 or 3 passes to make sure I'm tightening everything down evenly. Then turn all bolts an additional 90 degrees in sequence.

HO2S slow responce bank 1 sensor 1. This means an oxygen sensor bank one is the first O2 sensor in exhaust manifold off #1 cylinder .The code is PO133. You should change your fuel filter then do a tune up plugs cap rotor wires if requeried and pcv valve along with air filter. This is if you haven't already damaged your catylitic convertor or your fuel pump .Vehicles need to be serviced if you want dependabulty if not buy a new car every couple years or so

TCC is a code depending on what code you are getting . That has to do with the torque converter in the transmission. Likely a valve is stuck . Have the thing serviced before its to late its not that expensive compared to a rebuild .

Wild guess a loose wire but occasionally hits the connection or shorts to a hot (12vdc) supply. Or a bad wire to "connector" connection. Intermittent problems are hard to solve. You will need to look carefully at the related controls and location to see if you can find what I describe. It is possible the problem is elsewhere in the wiring system. Just takes time to hunt down. Just purchased? from dealer? I'd take it back ask them to "hunt". If from individual, that's probably why you got a "good?" deal. I'd still go back and ask them to fix, "nicely". You may get lucky and be able to find the problem. Sounds like issue is on the supply to the switches for all the problem devices. Could be as simple as a fuse or connections to this "circuit" to and or from the fuse. I'd start first with the fuse that serves this circuit. Fuse cover should tell you which fuse is for what device/s. Hope this helps and it turns out simple.

Try the fuel pressure regulator. Check the pressure specs and see if it is within limits. Too much or too little will cause your problem. Good Luck!!!!

There is two screws under the tray in the console. also, check around the shifter knob for a small square with a removable cover or plug. this is a shifter release button that can be engaged with a pen or toothpick. this answer is for a 1998 malibu but it might be the same as a 1999 malibu.

White smoke usually means oil in the mixture somewhere. Could be a head gasket issue. I'd see a local mechanic.

the lug pattern should be 5x100mm, you having the loaded malibu it could be the 5x125mm. if you still have the factory aluminum wheels on there then you can either take one off and look on the back of the wheel you will have to look closely it will tell you though, or you can go to www. tirerack.com there website will navigate you through and give you the proper size. hope this helps. sorry not more specific.

Sounds like you didn't put the pushrods back in the proper locations. There are two different lengths in this engine and you may have one backwards

Check your fuses, your main power source has failed somewhere. Sounds like it is grounding out. Retake your foot steps and see where you hooked up all your wires. Also check your fuel pump pressure and check your spark. Make sure it is strong. For you to have lost all power, I would check all my fusible links all the way to the starter.
