dropped my engine coolant cap
 

lost my engine coolant cap in the engine bay thinking it was the washer fluid. and i put washer fluid in the engine coolant filter.

Edited: Please check the bottom of page.. Help

It's probably stuck on top of your underbody tray, Im guessing.

I wouldnt want to get gunk up in my washer fluid for fear of clogging the lines, but that's me...

It's not critical, but you should keep looking for it as it is there somewhere.

pull out your engine and see where it landed.

Lol

My engine compartment stays pretty clean - very little road dirt/dust. I wouldn't be afraid to run without the cap for a few days while looking for the lost one or obtaining a replacement. See any of the oil change DIYs to see how to remove the cover on the bottom of the engine compartment.

thanks guys. ill just keep looking for it, if not ill have to buy a new cap. i dont know where though....

Remove the engine undershroud (like you would to do an oil change). It's probably down there. You could probably lift the car (use the scissors jack in the hatch if you don't have one) and tap on the bottom of the undershroud to determine if it fell down that far before actually removing it. Though I suspect you will have to remove it regardless to get the cap out.

Any dealership should be able to get one for you. Or there may be some aftermarket options.

Just about any auto parts store should carry replacement caps. Might be labeled for coolant overflow bottle or other under-the-hood bottle.

My guess is that Nissan doesn't sell just the cap, but all it costs is a phone call to find out.

... order one from the dealer.

:bowrofl:

so i found out its not the washer fluid cap... i am so dumb wow... my washer fluid is good now because i found where it was..... :shakes head::shakes head:

what is that white filter thing? i put some washer fluid in there.... !#@$! please help ASAP.... is it going to cause some damage to my car?
what even goes in there?

That's the engine coolant (antifreeze) overflow bottle. If you haven't run the engine since adding the washer fluid, you should be OK just draining and rinsing the bottle.
I'm not sure how the factory coolant will react with whatever in in the washer fluid (alcohol?), but I wouldn't take a chance. If you have run the engine since adding the washer fluid, I'd drain/flush the whole system. Hopefully someone will tell you that they are compatible.

That's a first...

yes im sure it is... hahahah

thanks for the response. ive been driving since for about 4 days. . . damn i should've known... my engine coolant (antifreeze) was pretty much empty, do i need to refill this soon as well? anyways more responses would be appreciated!:tiphat: I lost the cap for the engine coolant then... is the cap required? or can i still run it without.
