This is to see just how many people have had problems or multiple problems with the Radiator Cap. I'm trying to get this reported to Nissan if there's enough to warrant a report.


Here's a pic of what the problem might look like:

Sorry Pops... No problem with mine. However, I have read multiple threads on here about it. It is also the cause of some codes that members couldn't identify. I don't know that it's a rampant problem, but there are some who have experienced it.

There is already a TSB for the cap leaking. You need a new cap.

Already got one for free from the dealer. I'm trying to get it reported because the replacement caps aren't any better. ;)

Mine was bad until they put a new cap on there. I haven't had a problem since. Maybe you just have bad luck?:dunno:

Oh, I'm sure you're right about that. :D It just seems like the Metal and Gasket are thinner and more flimsy than any that I've had before.

$20.00 ???? :eek: Unless it's a NISMO, the cap only costs $3.00.

take the radiator cap off turn upside down bend the two tabs that lock the cap to radiator make the cap fit radiator as tight as possible.or hold cap in hand bend tab's with channel lock pliers. i did this to my cap fixed radiator never leaked again.the dealer ship not smart enough to do this.hope this helps.

Now that is a great suggestion. If the seal is good, just a little adjustment will do the trick. Good to know!

Thanks

If the cap is cheaply made, which it is, and leaks again after being replaced. Then yes, it is a huge deal and warrants a report to Nissan to get them off their *** to make a better cap. :bang:

the OEM cap is a POS!... around 15k miles, I noticed the stench and spotting of coolant... I checked all the hoses and when I looked at the cap, I noticed the sizzling water and vapor... took it into the stealership, the service manager (who is also a POS!) told me, "the coolant fluid was overfilled..." so I told him, "You're fahking guys did the service, so they must've overfilled it and jacked up my cap! What you going to do to fix it???" When he figured his guys did the fk-up, he replaced the cap and had the manuel laborers spray out my engine compartment, but the spots that were burnt in are still stuck, so it really didn't help anything... I have since purchased a Nismo cap, and boy does that thing ever seat and seal... My advice... if your stealership will not give you a $3 replacement cap, get the Nismo cap or equivalent, it's worth the money to not having to worry...

Acting??? No acting here, it is a big deal to me. It is a big deal when it has to be repeatedly replaced and the Auto Stores don't know the right one to use and we're stuck going back to the crappy Nissan one.

Maybe it's not such a big deal to you in your pick-up but for me, this is my family hauler that we travel cross-country in. The last thing I want is to have the family stuck up in the Rockies to find out too late that the radiator is out of water. I don't know about you, but my truck stickered for $48k. Please tell me of another $48k vehicle on the market that needs the radiator cap replaced every 20k-40k.

You don't have to worry about it if you choose not to. Whether they do anything about it or not is another story and I won't lose much sleep if they don't because some of the guys here have great suggestions about just bending the tabs and so forth but it's still worth bringing to Nissan's attention.

When you have a family and you're the one traveling with them in the middle of nowhere and your Hot Temp light comes on while driving at 4am Sunday morning and it's 15 degrees outside so the family has to freeze a little just to give the engine time to cool down and if you can find a dealership, it doesn't open until Monday morning, then you can come back and tell me that it's just a friggin radiator cap. ;)

I realize you're a Nissan Tech, don't you think that you might want to consider that there could be circumstances that can turn something very petty into a big deal??? ;)

Does anybody have a full copy of the TSB. Nissanhelp tells me I can't download it. I know it's just a bad cap, but my engine was spotless, and now it's freakin covered in antifreeze. It's all over my S&B intake tube. Grrrrr!
