I am conducting an engine swap and heard that the water pump and some sort of tensioners should be replaced before putting it in the engine bay because of how difficult it’ll be to do while it’s in the engine bay? What are those parts?

thanks in advance

 

Which swap? Different swaps call for differing parts.

Please be specific as to engine, chassis, purpose, etc. Being specific now gets better answers later

 

It’s a B18C1 engine from a 00 Integra going into a 96 Civic for the purpose of more power TIA!!

 

i heard the same but could never confirm if it were smart to do maintenace or not, to worry about the repercussions of not doing what should've been done, end up pulling everything apart just because my stupid dumb ****** *** didn't do what was needed. yeah, no confirmation ever on that story

 

IOW....


Yes replace every seal, gasket, water pump, put on a new timing belt, and do a valve adjustment while the engine is on the stand.

MUCH easier to do, and you'll get it done a lot faster as well with nothing in your way.

 

Whenever the engine is out, always replace every seal/part you can, especially the clutch, rear main seal and throwout bearing....along with timing belt, etc.

 

If if you don’t mind me asking what is included in the “etc”?

 

Timing belt job consists of replacing the timing belt, water pump, tension roller, and the camshaft and crankshaft oil seals.

I don't like replacing the seals unless they are actually leaking. It is pretty easy to mess up the installation of a seal and have a leak.

 

I usually replace:
- rear main seal
- clutch
- flywheel (resurface or lightened one)
- throwout bearing
- oil pump seal (aka front main seal)
- timing belt tensioner
- timing belt tensioner spring
- water pump (new mounting bolts as well)
- thermostat
- all compression clamps
- cam seals (behind the cam sprockets)
- valve cover gasket
- spark plug seals
- accessory belts (AC, PS, alternator)

 

On B-Series engines it's good to do the valve adjustment or at least check it while you have the cover off. I bought and sold 4 high mile (B20) CR-Vs over the years and every one was out of tolerance when I checked it. One already had burned valves ($$$ to machine and rebuild the head).
