Lol!! I can imagine!!!

 

Please explain how.
Do you take the gas tank out?

 

Why on earth would you do that?

Just taks a couple of pieces out of the way on top.

 

Well the space between the waterpump and the firewall sheild is less than an 1/2 an inch....how do you pull the waterpump out far enough? Getting at the waterpump screws (below)should be fun unless you have very small hands and arms.
I know when my waterpump failed I took the hood off, removed the stuff at the top of the motor and decided I could not get my hands down there without somehow ripping out that shield between the motor and the gas tank .
It was easier to pull the motor....which is what I did.

So , specifically, how did you do this?

p.s. I suggested removing the fuel tank because there is enough room to access the waterpump
with the tank out of the way.

 

Brian- That is where the experience comes in. The 1.3 GB of WSM I have only says to change the seals whenever you pull it. Good advice, but does not tell you how to pull the pump.

Sounds like any normal service manual. It tells you to pull this , pull that to remove something yet does not give you any detail. Or it will tell you to tear apart half the vehicle just to change out a spark plug

 

Your post has me confused you said you pulled the hood and the "stuff" at the top of engine if you did that the pump is right there just remove it. You don't pull the pump out toward the fire wall it would lift up [out] of its mounting area, the panel in front of it is not in the way. secondly if you have removed the engine before to remove the pump(absolutely no reason to do this) and seeing where the water pump was I'm not sure why you would be asking the question now. There really aren't any tricks or unique ways to get it off there are four allen head bolts on the lower part of the pump that hold it to the block. IMHO the only question that needed to be asked(based on your above described experience) is if it can be removed without dropping the engine we have established that it can so just remove the hood and the stuff on top of the motor and there it is.
If it doesn't feel right to you I would suggest having some experienced mechanic do it.

 

To pull the waterpump (part 8) out you remove 6 nuts (part 16) and pull the pump forward towards the firewall. What you are suggesting is that you remove the waterpump mounting body (part 1) that the actual waterpump bolts into as well as disconnect the heat exhanger (part 51) and move the p/s pump body for access to the mounting bolts & replace waterpump heat exhanger sleave (seal) $249.20 (part 35).

Thanks for the information.....by the way there is no need for the attitude.

Can you advise how many billable hours the complete re&re waterpump service (with the motor in)takes?

 

That is exactly what I was suggesting if you are going to do any type of work on the water pump then it is time to do the service/clean work on the rest of the system by removing the housing. Such as clean any corrosion from the hose connection areas part 24, 22, 25 and the area around the large hose connections and heat exchanger, also replace o ring #21. Also check(clean if needed) the passage ways in the housing, replace the thermostat etc. there is more to do than just replace the pump ie; if the pump needs work than the rest of the above will need attention. And depending on the condition/age of part #35 replace it if it needs to be replaced. These cars are not cheap to maintain so if you are going to play you will need to pay sometimes. What good will a new water pump do if #35 fails? My original comments in my first post were related to two facts you gave: dropping the engine and taking the car to a point of seeing the water pump, if you had done those two things than what I have said above would have been a no brainer, ie; your experiance level would have told me you already knew that you just shouldn't remove the water pump (vs. removing the complete housing) that there is more work needed. So I assumed you meant housing when you were using the term "water pump".
Now as to the attitude problem, your question in post 8 seemed redundant to me. With what I read for your experience level, getting parts removed down to the water pump at one time and then removing the engine another time to replace the pump, it made me think you had not done this work and it is OK if you hadn't just don't blow smoke up my butt. Also why replace the pump again if it had already been done? What I'm saying is the answer Brian gave is all you would need to know if you had done the past work. I can't put words in Brian's mouth but I am assuming he was thinking similar thoughts therefor the reason you got no further answer from him.

 

The original post was '355 waterpump replacement-must engine come out"
The answer is no if you remove the waterpump body but yes if you remove the waterpump alone.

This question has been asked many times but the people who answer never explain how it is done.
Also the people who claim to have done this service with engine in state that the job is a very difficult, time consuming and frustrating job (due to clearences).
Nobody has said how many billable hours are involved in this service.
The purpose of this forum is to freely exchange information because there are several ways to tackle different jobs. For example...the correct way to replace the timing belt on a NSX is to install it with the motor in.....a very frustrating and difficult job due to the lack of clearences ....some techs will pull the motor to avoid this experience. It does not mean that either tech is in error.....it is just a different way to do the same job. Also it does not reflect on the experience of either tech either.
So lets chill out and answer questions with more respect and less assumptions......or this forum serves no purpose.
