It is a timing chain, and 100,000 miles is a good time to change it.

SOURCE: nissan 350z.2004.overheating problems./changed fan

I am not aware that there are indeed two thermostats on the 350Z. I would be more suspicious of the water pump causing the overheating problem. Is the water pump leaking? Leaking is a sure sign that the water pump is defective, but I have seen water pumps that were not leaking, but were still faulty because they were partially clogged up. Anyway, hope this helps and best wishes.

Hi..my kia avella rpm reaches for about 1200 rpm when I start up in the morning and gradually decreases to about 600 rpm.but it takes 10 mins bfore the rpm goes down.is this normal?m And my engine loses...


Yes, that is normal operation for an engine. It needs to run at higher idle when cold and the computer does that through the temp sender. Make sure it's not excessive due to any vacuum leaks. This and the AC power loss would be exaggerated if the engine is not running correctly.

2005 350z touring overheats while in stop and go . recently ran just to High range while idle on very cold day. Coolant change and power wash radiator did not cure problem


Hello,
Here's something that's a very common cause of overheating, and it's easy to check.

How to test the thermostat in most vehicles;
Make sure the heater is off, start the engine and let it run for 6 to 8 minutes, ( this will allow the
engine to reach, " normal operating temperature "), from the inside of the vehicle turn the heater
temperature on high and turn the fan speed on high.
1. Listen very closely for a click sound from the engine, ( most thermostats make a click when
they open )
2. Watch your temperature guage, it should begin to lower as the coolant starts to circulate.
3. Usually within a few minutes the radiator fan will kick.


What the thermostat does;
It seperates your coolant into two parts. The first part is in your engine, the second part is in your
radiator and the coolant reservior. When the coolant in the engine reaches the temperature rating
on the thermostat the thermostat opens to allow the two parts of coolant to change places. Now
the cooled coolant in the radiator and reservior flows into the engine while the heated coolant flows
from the engine into the radiator and reservior to be air cooled by the radiator fan.

I really hope this helps you.
Donnie

It sounds like an low charging system voltage issue, the Bose draws allot of juice, have the charging system tested and the battery, Kragen and many other chain parts stores do this for nothing.
