water pump leaking

I just had my timing belt and assorted parts replaced two months ago along with the water pump. Yesterday I noticed a wet spot under the car. I checked it and it's coolant it's coming from the timing cover. I would take it back to pepboys to fix it but this whole thing has been a pain in the ass dealing with them. I'm going to fix this myself I have an impact wrench now so I can get the crank pulley off that's why I didn't do it in the first place. Anyhow what could be causing the leak not tightened enough? How can I tighten it without that tool can it be done? The tool is 145.00 pepboys did't have the tool either I'm sure that's why it's leaking. The guy said he modified a tool for a lemans to fit the lanos water pump. Any input is greatly appreciated. I was thingking a strap or chain wrench would work anyone had any luck with that or is it a bad idea.

I would do closer inspection when you remove the timing belt cover. If the timing belt tension is right, take a photo of your waterpump, with reference to the surrounding. Then when you replace it, you can put the new one exactly the same way. If the pump is leaking, its either the internal seal or the o-ring.

i think i am having the same problem. i had to add coolant today and saw some coolant in the pan (heat sheild) on the bottom of the cat. Traced it up into the timing cover. Is the o-ring on the inside of the pump or is it external? Which one would be leaking to the outside of the pump? Do i need to do a new pump or replace the seals and use the same pump?

Sorry for the 20 questions but i have to ask. Dont know alot about what is on the other side of that cover.lol

you will have to take off the pump to replace the O ring.

if the leak is from the contact area between the block and the pump body then it is the O ring, if the leak is from the hole on the bottom of the pump behind the pump's pully then you need a new pump.

I was looking at my old parts and the o- ring to the old pump is missing. I'm wondering if it was left in the housing when the old one was removed. Also how hard it it to take out I read another post that said something about having to take off one of the mounts and pry the engine forward or backward to clear the pump pulley of some obstruction. Thanks.

if the o-ring is missing then take it back to pepboys for them to do it for free this time though correctly. that way you do'nt have to deal with it plus you do't have to waste money on more coolant.

How much did pe-boys charge you to change the pump?

I don't know if the o-ring is there or not on the new one, what I was saying is on the old one I got back there's no o-ring and I thought there might be a chance the old one is stuck in the housing.

they charged me $321.00 for labor on timing belt and related items water pump and serpentine belt and ac belt. Of course I supplied all the parts.

Hi,
If the mechanics left the old O-ring in the block and put a new one on top of it?
That would for sure be the cause of the leak. They will have to "make it right" as said above.
It sounds like they did something wrong for sure.
If I were you ? I would take it back and insist that they "make it right".
Take a big friend with you.

(Of course 'insist' in a polite way.)

You shouldn't have to pay anything extra. You paid to have it done correctly. It's obviously not correct.
Good luck !
p.s. I need an alturnative water-pump wrench myself. Anyone know what works as a substitue for the factory tool ?

i don't think it is possible to "leave" the O ring in the housing... on my old pump the ring was stuck to the pump body and it was beyond "re-use" condition... the mechanic could have simply thrown it away or it might have broke in the process of removing the pump.

it is very much unlickly that this happen, anyways you can forget this idea if the leak is not from the mating area between the pump and the block.

321USD for timing belt job? i should move to USA and open my own garage 'cause it is very much profitable their... the sum of money you were charged is so much that if converted to fuel it would be equavlent to the price of 348.50 gallons of 92 octane of fuel, multiply that with your current USD/gallon rate and you will see how expensive it is compared to our labour prices.
