Asked by cp7600 Feb 04, 2018 at 05:39 AM about the 2002 INFINITI I35 Luxury FWD

Question type: Maintenance & Repair

I just bought a 2002 Infiniti i35 couple weeks
ago. Drives solid just a little oil leak and
alignment was needed, I noticed last week
coming home from work it was getting hot.
Pulled over at AutoZone used their reader,
says something is wrong with the cadilet
converter and sensors, but I drove home it
didn't get got again until yesterday morning
just drove about a block and it was hot. The
first over heat I assumed it was the drive
from work I commute 350+ miles a day
monday to friday and after sitting in traffic I
figured it was that. Second time was the first
drive of the day so that made me concerned.
Any suggestion on what's the cause? Also
there's a rattling noise coming from under
the car it's not loud nor grinding it's more like
a rattle. Any suggestions on that?

see if the fans come on when it gets hot , get the definitions of the codes , what does the exhaust look like ? have someone rev the engine and see if a healthy blast of exhaust comes out the tail pipe to see if the cat. is clogged , , look in the bottom of the oil foll cap what do you see ? over heating for what ever reason can ruin a head gasket and a blown head gasket will cause over heating , you can replace the thermostat and check the condition of the coolant or have a compression test done for a definite answer

The fan does come on what would you consider a healthy blast of exhaust should be? What is the oil foll cap? What exactly would a compression test tell me? I do have a dime size hole on top ofmy over flow for the radiator would that do any damage or cause it to do what it's done? It only has over heated twice the check engine or service engine. Soon was on for about a week and went off, funny thing is the windshield wiper light came on the other day and I went to fill it up it didn't even use a quarter of the bottle before it was full. Could I tighten the cat my self? I'm not very smart when it comes to cars don't know much

look on the bottom of the oil fill cap , scan for codes even if he light ain't on , a compression test will tell you if the head gasket is blown , you can't tighten the catalytic converter
