Replace water pump in 1991 318

    • 1

      Follow these steps and it will help. But nothing is as good as a Video. YouTube would help at that. Drain the radiator by twisting the drain plug at the base of the radiator in a counterclockwise direction with a wrench until the radiator fluid begins to exit from the center of the plug. Tighten the plug back into the radiator after the radiator is drained.

      Disconnect the intake manifold hose, the heater hose and the lower radiator hose from the water pump. The intake manifold hose is located on the right side of the top of the water pump. The heater hose is just to the left of the intake manifold hose, and the lower radiator hose is located at the bottom of the water pump. Each of the three hoses attaches to the water pump with a band clamp. Loosen the screw on each band clamp with a flat head screwdriver then pull the hoses off of the water pump.

      Disconnect the alternator brackets from the water pump. The alternator uses an upper and lower bracket, each of which is secured to the water pump with a single bolt. The opposite end of each bracket holds the alternator in place with a bolt. Loosen the bolts which hold the alternator to the upper and lower brackets, then rotate the alternator towards the engine to slacken the alternator belt. Pull the belt off of the front of the alternator, then remove the bolts which hold the upper and lower brackets to the water pump with a wrench.

Diagnostic code says LEAN

You may have a vacuum leak. The leak may be at the intake manifold (upper or lower) or any of the vacuum lines leading to the various sensors or the brake booster (larger hose leading from the upper intake to the large round device behind the master cylinder near the firewall on the drivers side). You should find (usually) a vacuum line diagram affixed to the underside of the hood near the front, or on the framing near the radiator. Also listen for a tell-tale hissing when the engine is running this may help you locate the leak. Hope this helps you.

I can't get the thermostat housing off the engine to replace the thermostat. i've removed the bolts, upper radiator clamp and hose from the elbow going to the housing and it is loose, but it wo'n tcome off...

The thermostat is not under the upper housing. The thermostat is behind the lower housing that the lower hose is connected to.

If you are changing the upper housing known as the water outlet housing because it is leaking you are on the right track. You will need to remove the intake plenum on top of the engine and the upper radiator support. You will then be able to access the bolt on the backside of the engine that bolts the pipe retainer in place and disconnect the hose from the pip. The upper radiator support needs to be removed in order fro there to be enough clearance to pull the whole assembly out.

I own a impala 2003 and i would like to know how to change the thermostat on it.The motor is a 3.4 liters

Drain radiator. Remove upper rad hose from thermostat housing. Disconnect air intake hose from throttle body. Remove throttle body from upper intake manifold, disconnecting the 2 rubber hoses to the heater line. You may also need to disconnect the fuel line. Remove the exhaust crossover heat shield and loosen the crossover pipe from both exhaust manifolds but don't remove crossover completely. You should have access to the 2 thermostat housing bolts, remove upper bolt but just loosen the lower one about a half inch. Pull the housing out and up from the intake manifold to access the thermostat. Clean the mating surfaces with a gasket remover. replace thermostat, apply a light coating of rtv sealant to both sides of the new gasket. Replace thermostat housing with the gasket to the intake manifold. Apply some rtv to the bolt threads before reattaching housing. Tighten bolts snugly but do not over tighten. Tighten exhaust crossover and reattach the heat shield. Install throttle body attaching the 2 little hoses at the bottom, its a good time to replace these hoses and clamps. Depending on the condition of the throttle body gasket you may need to replace it also. Reconnect the fuel line (if disconnected) Reconnect air intake hose to throttle body. Reattach the upper rad hose to housing. Fill rad with coolant 50/50 mix with water (make sure to use the same type antifreeze that is in the system, they say you can mix green with red but I wouldn't recommend) Leave rad cap off start the car and let it warm up until you can see the coolant circulating and ad coolant as necessary until full. Now there is going to be some air in the system that you need to bleed out. There are 2 bleeders on this system, 1 is on the top of the thermostat housing, and the other is on the metal heater line on top of the water pump (the one that goes across the front of the engine and around under the throttle body that the two little hoses attach to) Bleed the one on the housing first (its the lower one) open it until fluid comes out then tighten it. Then move to the 1 on the heater line(above water pump) loosen it until fluid comes out the re-tighten. Fill recovery tank to fill line replace the rad cap and take it for a ride, watching the temp gage closely. If the temp goes higher than normal than there is probably more air in the system. you'll have to bleed it again.
This is a very labor intensive procedure and I do recommend buying or checking a service manual out from your local library. I've done these in the past and to be honest I just have the dealer do it now. A system flush and thermostat replacement was around $230 the last time I had it done, but it comes with a warranty. And you wont have to rent or buy a fuel line disconnect tool if you end up having to disconnect it. These are the hardest thermostats I've ever replaced.

How do i change sparkplugs for 2002 mercury couger v6

To remove the spark plugs, remove the covers and you will see how simple it really is. The spark plugs are hiding under the covers.

Not only you will have to lift the covers, but to reach the back three you will have to remove the valve cover. Here's how to:

1. Remove the water pump belt cover (the black cover in the front of the engine compartment that has ?Duratec? on it.) If you have a 1996+ vehicle, you should think about removing it permanently, since it only serves to trap heat and slowly kill the IMRC box electronics.
2. Disconnect the following electrical connectors from the: MAF, IAT, TPS, IAC, and EVR. The EVR connector is black and is located at the very back of the upper plenum, next to the firewall.
3. Disconnect throttle cable from the TB and the cruise control cable, if equipped. For 1995 5-speed vehicles, take care not to lose the metal clip for the throttle cable when you are removing it. Once the cable is removed the clip will slide right off.
4. Disconnect the vacuum lines from the EVR. You may have to wait until the upper intake is unbolted and partially removed for better leverage.
5. Disconnect the vacuum lines from the top of the upper intake. Push down on the black plastic collar with a screwdriver and hold, and then pull the plastic line out of the intake.
6. Remove the air box along with the MAF and accordion tube.
7. Unbolt the throttle cable bracket from the upper intake (three 8mm bolts, one 10mm nut). Set bracket and attached cables aside.
8. Disconnect the air bypass hose at the upper intake. It connects right next to the IAC valve.
9. Disconnect the hose from the PCV valve that goes to the upper intake, underneath the throttle body. This is also a good time to change the PCV valve.
10. Unbolt the EGR valve from the upper intake.
11. Unbolt the upper intake. 12. Carefully remove the upper intake and set it on top of some clean rags or newspaper. It will likely be oozing some oily gunk out the bottom.
13. Cover the openings of the lower intake with clean rags to keep anything from falling into the openings. Anything that falls in will likely end up in the head or the cylinders themselves.
Now you are free to remove the back plugs

My 2002 Ford Explorer wont crank!

I'm assuming the coilpack got wet!! Check if there is any power to the coil before changing. If thats fine, replace the coil. If there is no power, check your electrical circuit for the coil. Hopefully this helps

My 2002 Ford Explorer upper hose blew off while on highway. immediately exited and seen the hose. re-attatched hose, put water in truck and not it will not turn over. mechanic shop tested wires and no...

Does your engine turn over?When you say your upper hose blew off To me it meant your engine ran hot.You put the hose back on and filled the truck with water.So you drove it to the shop?Did you have to tow the truck after this happened?I don' know what to say! It seems like you have a blown head gasket,or you blew your engine,I need more info to help you.

Cant find the thermostat on my 1990 honda accord

Find your upper radiator hose and follow it back to the engine. There should be a metal "bracket" that the hose joins with a hose clamp. You'll find your thermostat in here.

have you checked for vacuum leaks? thought mine was spark plugs and found broken vacuum hose attatchment behind throttle body to manifold was broken... that was my problem, maybe yours too?
