Is there anything I should check before putting it back together?

also i noticed it was very black in the uim. Is it recomended to clean it?

just curious

 

Just clean it out.

 

i sprayed air intake cleaner in mine clean of the egr guide tube, clean inside th uim, clean the iacv and throttle body, once you start your car it will be smoking blue so dont be surprised when you see blue smoke coming out it, if you have more concerns plz ask

 

Why is it off? Did you change out the rear plugs and the rear valve cover gasket? Knock sensor is a lot easier to change with the UIM off...

 

The UIM doesn't have to be taken off to change the rear plugs.

 

^ yeah, i was WTFing on that one.

 

If you haven't already, you could change out your knock sensor....it should be real easy with that off.

 

replace that small coolant hose in the back, its a pain in the butt to replace

 

Yeah i need a new coolant hose...one of them snapped into pieces while i was removing the manifold....and i have it removed to change two of my injectors that took a dump on me.

Would Carb/ TB cleaner be fine to clean out the UIM? Yeah Ill prob removed the EGR tube and clean that out too...my IACV has 26k on it..the previous owner changed it and its not too dirty

MY gaskets are all fairly new...i got a new IACV gasket though so ill probably do that

 

Or SeaFoam.

 

seafoam is like $8 bucks a can here...i have about 4 spray cans of CRC so ill prob just use that...and a microfiber cloth

 

good call.

 

That Deep Creep stuff is a little more expensive, but I like it because it's concentrated. Well worth the money IMO, but if you have cans of CRC fawk it. It should work just as well.

 

WHy would it black inside the UIM...jus curious.

 

LOL, I get my Max's and Altima mixed up.
The Altima you have to remove the UIM to replace the rear plugs.

I've done one of the Max's, yeah, no need to take it off for that.

 

When I took my UIM off it was nasty inside. So I went to the store and bought a can engine D-greaser, went to the self wash and washed the UIM with a pressure washer inside and out till it sparkled in side and out. I all so did valve cover gaskets, cleaned EGR tube, IACV, TB, and replaced knock sensor and PCV valve. It turned out good for me hopefully it turns out good for you and it also made the car run smoother.

 

i let mine soak with tb cleaner and let it drain out...then dry...then wiped it down and used a dremel tool with a polishing head and polished as much as i could of the upper and lower

 

Im all for cleaning the car. But i get nervous when cleaning the engine compartment. I have never done so cuz i dont want to short anything

 

im talking about cleaning inside the manifold...not the outside....and as for cleaning the compartment...you wont shrot anything out...just put a bag over the abttery, cone filter intake if you have one, and the alternator and hose her down....while shes cold not hot

 

Just use rim cleaner + garden hose if you're afraid to goto the quarter wash like I am.

It's not show worthy yet (didn't really wait or did it a second time over), but i've gotten a few "ooh, this car is how old again" comments.
