My g35 is gushing coolent

Okay so I just got my g35 yesterday I got to my girlfriends and I went back outside and there was a puddle of violent under my car, I popped the hood and started filling it with coolant to see where it was coming from and it looks like itís coming out of the side of the head right behind the thermostat or it could be coming from the thermostat housing but not sure but there was a hose that looks like it went into the head right there anyone have any ideas I need HELP!

Get an inspection mirror and find out where it's blowing out from. Probably a ruptured coolant hose.

Moving this to the technical forums since it's not exactly a new member introduction.

More than likely your hose to the thermostat has failed. Pretty common on higher mileage cars, how many miles are on your G? Did you have any sort of pre-purchase inspection done on the car before you bought it? We highly recommend spending the $100 or so they cost to get a bigger picture of what you're buying, what condition it's in and what future repairs you should expect to run into.

Other cooling issues to watch out for would be any of the other coolant hoses and their clamps, failing or failed thermostat, faulty radiator cap, cracks in the overflow tank, falling levels of coolant in the radiator and most importantly the radiator itself. The stock radiators are plastic pieces of junk and it's very common for them to crack and leak as the miles increase on the car. If we can get 100K miles out of one that's considered a blessing. Good news if you can turn a wrench is the radiator, hoses and thermostat are all relatively easy DIY jobs. If you don't have this ability though paying someone else to fix an aging luxury car can get expensive quickly. If you notice you're losing coolant but can't find a leak getting the system pressure tested is an invaluable process to pinpoint the issue.

Hopefully you've set aside a nice maintenance fund and you got lucky and bought a well maintained car. If maintenance wasn't kept up with you could have a money pit on your hands and none of us want that. Please let us know what the issue is when you figure it out, your posts might help the next guy that comes here looking for answers.

Yeah if the metal is cracked then you're looking at a dealer replacement item (or used through eBay or such). Are you sure it's not just the gasket that mates it to the engine?

I would remove the item and see if it can be soldered/brazed though.

Should be Nissan part number 21022-AQ00A

Any time anyone has a coolant leak that's not totally visible it's a very good idea to have your system pressure checked! Cost is minimal and you might find a week area in the system that isn't part of what you're dealing with now! Quality radiator shops are the best place to have this done since that's their only job!

Or buy a Standt tester with the proper adapter and do it yourself.
