Replace with a new "AC Delco" brand and try to stay away from the cheaper ones. Location of this will be towards the front of the engine so if you open hood the engine is sideways it would be towards the passenger side.With key off, disconnect the clip (take ur time and do not brake the clip) and then remove the bolt that olds the bracket (use a metric wrench) then slide the sensor back. To install do the same. Easy task.

you need to have the code finder to be attached to the car! after you have the exact code than you pass to the second step and change it eventually!

replace the coolant temp sensor that controls the fans.

TRY THIS SITE ON YOUTUBE.TYPE IN "removing 1999 Chevy 3.8 water pump at you tube"step by step video. better than a detailed report.good luck not a hard job if you can wrench.Cowcamp

u can buy wrenches in store-but take a bike inner tube and grab hold of filter n twist--unless its real tite--use jackstands if u raise car-a jack alone is unpredictable--twist on new filter til it stops then slite twist til tite-the heat will secure it

The waterpump is located on passenger side of the car. Its location if you were standing looking from the passenger side at the engine is at the top right of the engine.There is a pully at the top of the engine that has 4 10mm headed bolts should be a non grooved pully.Loosen the bolts on that pully with the belt on once you loosen these bolts but do not remove them just yet.Using a 3/8 drive ratchet find the belt tensioner and release the belt making sure you remember the belt routing.Typically the the belt routing is printed on a plastic shroud that is just above the waterpump. Once you have removed the belt take out the 4 bolts that you previously loosened.Remove that pully now and the waterpump is right behind that. Sometimes the pully sticks a bit so you may need to put something behind it to gently dislodge it.There are 5 bolts on the waterpump the head of these bolts are 5/16 or 8mm remove the the five bolts using a quarter inch drive ratchet.Once this is done you may need to dislodge the pump.A dead blow hammer works well or a block of wood and a hammer could be used in a pinch.This should not require alot of force.Just a few taps should do it you are just breaking the gasket seal at this point.Now that the old pump is removed the old gasket needs to be removed from the waterpump housing. make sure all old gasket material is removed so the new one will seal properly.Take out the replacement pump and and line the new gasket on the waterpump once you have done this remove the gasket so you can adhere the gasket in place with a thin coat of rtv or weatherstrip adhesive.Now you ready to reverse the process to put it back on.Just make sure to line up the five bolt holes and your ready to go. Hope this helps.

older cars need to be run alternators sieze up fuel pump gets gummed up .the gas is probably bad so this will make it have no pressure

may not be at operating temp. to run the motor or fan motor is bad or broken wire or wire connector pulled away from fan motor

Be more specific please

No you don't you have transmission fluid In it. Engine oil will never get into your coolant. You need a new radiator

Hi, you may want to bypass your steering column for the passkey system. There is a good procedure posted online that I have used successfully in the past. Please read this and let me know if you have questions.
