Gurus,

I may need to replace the Coolant hose that is behind the engine which leads to water pump to fix a minor leak right at the place it hooks up to the water pump.

Please let me know if it is a difficult job or a average DIYer can do it?

 

Do you know if there are 6 cylinders in this car or 4 cylinders. If it is 4 cylinders are you talking about the metal pipe that goes across the back of the block? It was very nice of you to say 97 Accord, that is way more info then most people post at this website Post back, I might be able to find a parts breakdown for you.

 

Sorry hondadude, mine is a 4-Cyl Accord Lx.

I am not sure if it is a metal pipe or a regular coolant hose, it is the one that connects to water pump from thermostat housing.

please help.

 

That sounds like the metal pipe running alongside the back of the block (part #11). Looks like there's O-rings at both ends. You gotta take off the thermostat housing (#8) in order to remove that pipe, to put new O-rings on.

 

Now that we all understand what needs to be done, can you tell me if it is a DIY job?

I have replaced the muffer, radiator on my car myself and do oil chages.
Do you think replacing the metal pipe is something I can do?
I am concerned if I can get enough clearance with just using Rhino ramps.

Also any advise on how to remove thermostat housing?

thanks

 

JimBlake,

how did you insert the picture in your post?

 

Changing the radiator means you know how to deal with coolant hoses & stuff like that. You can probably do this, but it's not fun laying underneath & having coolant drip on you. Can't be much worse than crawling underneath to do exhaust work.

Before you start, drive up on your ramps (make sure they're straight & solid). See how much room you got to work with. Then decide if you wanna do it. I think the job itself is easy, but maybe there's not much room for your hands & tools.

Take off the air intake hose to make plenty of room at the thermostat. Unbolt the outer t-stat housing & pull the hose away. I think the main part of that housing is just bolted to the engine, with it's own O-ring (#25, get a new one of those, too).

ps. oh yeah... there's a little icon of a picture. Click that & insert the picture's URL between the tags. The picture can't be on your hard drive, it has to be somewhere that everyone can see it.

 

Maybe you do most of this from above. Maybe you only need to crawl underneath to clean out the hole in the waterpump - so the new O-ring at that end has a smooth surface for sealing.

 

Don't forget to unbolt #21 before you try to pry it out.
As for going at it from the top, I have found it eaiser to go from the bottom, you do not have the intake manifold to compete with then...

But I don't see any clamps or bolts to tighten the pipe at its two ends, so, how does it fit?
just a snap it in and seals itself?

 

There's a bolt (#21), but it just slides into the waterpump at one end, then you put the t-stat housing over the other end. It's kinda trapped between the two. That's why you have to take off the t-stat housing first.
