I have a 2003 350z, 6 Speed Manual.

About a year ago I was driving on the interstate and got stuck in traffic, when I detoured and started driving away I noticed my temperature was through the roof. I immediately pulled over and could tell my radiator had cracked. I left it over night in a parking lot and put a new one in the next morning.

All has been good since then, it has not ran hot one time.

This morning on my way to the office I was stuck in traffic for about 2 hours on the interstate because of an accident (moved about 2 miles in that time). I was relatively idle and not moving much as you can tell. I looked down at my instrument cluster and noticed that my temperature gauge was again through the roof. I quickly pulled to the side and took the mailman's lane up to the next exit.

As soon as I started moving, it cooled off and didn't get hot again even at red lights and in the 5 minutes I let her run when I got back to my house.

Is this a common issue with 350s?Any insight will help.

Thanks,

Sean

 

Not common on 350Z specifically.

Air in system? Bad thermostat? Low coolant? Fluke/1-Off?

 

either air in system or fan quit....fan motors are known issues.

get car warm and turn on A/C....both fans SHOULD be running.....flashlight helps to confirm.

 

Check the electrical plug(s) for the cooling fans.

 

its either one of these two items, period.

 

OP...you ever figure it out?

I had mine spike just this weekend......I have bled that damn car a freaking million times and driven almost 300 miles.

I did install a fan off amazon and wondering if it is either quitting intermittently or just not pushing enough air.

Upgrade time.

 

Never had issues before..but still built this for general over kill factor.


Spal 14s, dimpled and fully polished...even tho it will never be seen under my charge pipe..

 

did your shop get them installed?

I have one spal 14" but prob going with a 12" then I got to figure out the wiring.

like we discussed I was hoping on using temp activated variable speed controllers but that is beyond my skill level (not to mention my budget)

Thanks tho

 

also you going to use weather striping like the Mishu kit?

 

It's sealed yes.. cars still not running due to wire tuck tho.. i leave the wiring to them

 

i could REALLY use a pict of the profile of strip used to seal it.......since I have to do all this crap MYSELF. Too bad I always F something else up while I'm in there

Thanks

 

Yeah this is the only pic i have.. sent by the tech.. it's already been installed at this point tho.. sorry.

 

Fan(s).
