If it is from the Metal Cap, and is 3 years old, I would replace it. Dealer; or Store will have them, but I found it a bit difficult to find in many stores. Our caps are infamous for leaking. Bend the Metal Tabs just a little bit to make for a tighter fit. Do not use a Cap with a Spring Loaded Center, as our Radiator and Overflow Bottles are all part of the Pressurized system. The Plastic Cap on the Plastic overflow Bottle is the Pressure Relief.

That's what I was planning on doing but I didn't want to waist the money if that wouldn't do anything

when i changed my oil the other day i noticed some stains/ residue all over the intake tube, engine cover etc. so i started reading up on this. i'm a poor man and baby the shyte outta this truck, but today i got on the freeway and really got on it a few times and when i got home sure enough there was fresh stains and even wet spots. obviously leaking from the cap. i pushed down on the cap and fluid squirted out from under the sticker. truck is five years old and to my knowledge never had that cap replaced. so i guess its not even worth trying to bend this one? just get a new one right? i saw one by stant on rockauto for like $3. anybody using that one? what about the nismo caps? thanks in advance.

take it off and bending the tabs with pliers to make it tighters works, as long as the seal is still good.

i'll try bending this one. then i'll try a new oem one. if that don't work i'll try the nismo one despite the price tag. whatever it takes i guess. gettin kinda sick of crappy, feeble parts. crappy hoses, crappy clamps, crappy caps................

this morning i went out and removed the cap to bend it and coolant gushed out when i removed it. the coolant was all the way up the top of the neck. is this normal?

If you would've bled the pressure off the system by opening the reservoir tank first, this wouldn't have happend. So yes, it is normal.

gotcha thanks. the bending of the tabs seems to have worked. no new leaks from the cap however i think there's also a leak from one of the hoses. gonna cut off the end and reclamp it.
