I was wondering if it matters if the cap for the overflow is missing? Like does it make that much of a difference aside from it preventing it from spilling?

 

It will allow the coolant to evaporate faster, i doubt unless it got really full thatd itd actually spill out.

 

A boneyard would probably give you one. They're two or three bucks new.

That air wont get into the radiator or some shyt and *** up something will it? like how if there is air in your brake line...???

 

More likely debris of various kinds, which, of course, wouldn't be wonderful. Buy a cap (IIRC, they're vented), and quit being such a tight butt .

Just use a rubber band and some saran wrap (use your imagination) until you can get a new cap. And how did you lose the old one anyway?

 

I have some thingy I'm using for the time being but I was told by some lame apparently, that it made a difference. It's all good, and when I bought my truck, it was allready missing. and to the other guy who said to quit being a tight wad or wutever,.. OMFG dude it was a dam question and how do you know that I haven't bought one and was just wondering???

 

Ease up. All in fun (note the grinning face at the end of my statement). Not really any flames on this site.

the cap on my camaro was the same one that was on my 92 sonoma, im guessing GM mustve put the same cap on alot of vehicles around those years, the junkyards must have hundreds of them, id go there first

 

I didn't have a cap when I first got the car, so we just cut out a chunk out of a garbage bag and zip-tied that bitch on!

 

No

Stop being cheap and buy one.

Its in the HELP isle of the parts store. I paid 3.75 for it.
