Hi, I'm Don from 1A Auto. I hope this how-to video helps you out, and next time you need parts for your vehicle, think of 1AAuto.com. Thanks.
This is a second part of a two part series. In the first part, we took basically the front of the engine apart and removed the timing belt. In this one we're going to show you how to change the water pump, and then, put the timing belt back on, and put everything back together. The first set of tools are basically the same. You will need a 5mm Allen wrench, a razor blade and holder to clean off the gasket area for the water pump, a torque wrench, as well as what I didn't mention here was a catch pan for catching the coolant from the engine.
With these out of the way, you can slip the belt right off and out. Locate the drain plug on the radiator, right here. It's red. Remove your radiator cap. Unscrew your drain plug. Have your bucket there to catch it. There's an 8mm Allen bolt right in there and that's right below the water pump and if you remove that and have a container underneath it'll drain out your coolant to below the water pump level. In this case the bolt is too rusted in there.
We couldn't remove it so we're just going to knock the water pump off, and let it drain into the pan that way. Locate your two 12 mm bolts that hold the bracket to the water pump and to the alternator and power steering bracket and remove those. There are two more 12mm bolts that hold that bracket that are in behind where that power steering pulley is. We'll speed up, here, as we remove those bolts. You can see it's a matter of using different size extensions to get to the bolts. Once you loosen up one of them, the power steering pump can be moved, slid up a little bit out of the way to get to the other one. Locate your three bolts that are remaining holding in your water pump and those are 12 mm. We'll fast forward here as we remove those last three. So, that's seven bolts, in all, that hold that water pump in. Use a hammer to tap on the water pump to break it free. You hear that we broke it free. The water came out because we weren't able to drain from the plug beforehand. We have the catch pan in there to get as much of the water as possible. Grab the water pump and pull it out. You see, in the old pump, some of the gasket stayed with the pump. The other part of it is on the block and we're going to clean that up with a straight blade razor. Be sure to clean all of the gasket material off as well as you can. The better you clean it off the better it will seal when you put it back together.
We've got the old water pump and the new part. We've used a little spray adhesive on the gasket to hold it here in place while we put it back in. We'll speed up, here. Basically, Don just puts it down into place and then gets all the bolts started in by hand first, and then tightens them up. When you tighten these up, you should tighten them to between about 17 and 19 foot-pounds.
I have the old idler here. I've got the new one here and you can see they're the exact same and it's going to go in just the way it came out. We'll speed up here as we put the bolt in place for that idler pulley and then tighten it up. This should be tightened up between 25 and 30 foot-pounds.
The old and the new tensioners look exactly the same and they're going to go on the same way. I'm just leaving that loose for now.
Make sure your engine is in the right position. Shine a light directly at the front pulley. The light should go right through that hole and light up the red mark behind it. Then down, a little hard to see, but the white mark that's on your crank pulley should line up with the white mark that's on the block of the engine. Put the new belt down inside. When you've got it on, make sure that the teeth all line up on the belt and sprocket for the cam and for the crankshaft. Recheck to make sure that your timing marks are lined up. We're going to take the 5mm Allen wrench that we have, put in the tensioner, and press on it until the belt is firm and then tighten back up your 14mm. Torque your tensioner bolt to 38 foot-pounds.
Put your lower timing cover back on. I'm feeding the lower timing cover up and I'm keeping it to the right or to the front of the engine with the water pump inside of it at this point. Then I'm going to slide it over the water pump. After doing that, I'm going to feed it underneath the engine mount bracket and the idler pulley, the idler tensioner. It may require a little force. You can see right here this is where it hangs up. I'm just going to give it a little push and it goes right in. Fast forward as Don goes from the bottom and the top both to put the bolts on for that lower timing chain cover. Install the upper timing cover. We'll fast forward here some as we start the bolts in. Don't forget that there's a bracket that goes on the rear part of that timing chain cover. Make sure you put that in place and bolt it in place. We'll fast forward again here as we put the rest of those bolts in. Tighten them up nice and firm at probably about 15 or 16 foot-pounds. I'm putting the bracket back on, that goes to your engine mount.
I'm reinstalling the pulleys for the water pump and I want to put the dish side in, small one on first. Do the same thing with the big one. Put the dish side in. Again, we'll fast forward as we get those bolts started in and then we'll do the same thing we did to take it out. I'll hold the belt on the water pump while Don tightens each bolt. Again, you do have to have the engine lifted up a little bit in order to access this.
We're putting the motor mount back in. As you can see, we let the engine down a little bit to line things up. I'll fast forward it, here, as we just start all the bolts by hand, get everything lined up, and then start tightening them up. Once you get them all started, you can let the engine down back into place and then tighten everything up nice and firm.
Put the bolt back in the power steering reservoir and then the retaining screw. I'm going to put the washer and pulley back on. It's only going to go one way because it's keyed. Put the first in your pulley. Tighten it with my impact gun slowly. I'm putting the splash shield back up. You feed it from back to front, the easiest way to get it in, and secure it with your two bolts. Go ahead and feed the belt back up over the A/C compressor. Make sure it's on there correctly and pull it over the crank and feed it over the tensioner. Once I know everything's okay there, I can tighten up the tensioner. Checking the tension on the belt, we want it to be tight but have a little bit of flex. You should be able to move the belt up and down about 1/8th of an inch once it's tight. That's all set. Tighten up the 14mm on the end of the pulley.
Put the alternator belt back up and get it on the top pulley first and around the alternator and around the crank. I'm going to fast forward here slightly. The belt's back on and now we're retightening that tensioner. You basically want to tighten it up until you can grab the belt between the pulleys and you should be able to move the belt up and down between 1/8th and 1/4 of an inch, actually closer to 1/8th of an inch. Once it's that tight, then you can use your 12 mm and tighten the bolt that's on the back of the tensioner that goes into the alternator.
I'm tightening up the lower nut on the alternator. I'm reconnecting the battery. Speed it up here as we refill the radiator. Refill the radiator to about within an inch of the top and then fill just using the regular coolant fill. Drive your car a little bit and check the fluid the first few times you drive it.
