What are your thoughts, guys I see some threads here and there, and its got me concerned....since a shop just put a "OEM equivalant" thermostat.
I can only assume its a piece of crap aftermarket.

should I be ok ?

 

I'm not sure why you'd assume it's no good.

Do you purchase parts from either on-line retailers or at your local parts store?

Those are OEM equivalent replacement parts.

I think you might be either surprised or disappointed to know that many parts purchased from your Nissan dealer or from your favorite genuine Nissan parts on-line supplier are the same parts or are at least parts manufactured by the same entity providing those parts to the local store and to the on-line retailers.

I think you'll be OK.

 

thanks dude, well see, im hoping its fine as well. i just found a bunch of threads warning about aftermarket thermostats, and considering what overheating can do to a car its pretty sketchy and unsettling.

i also have personal experiences with non Nissan OEM sensors etc and the aftermarket do not hold up and are a complete waste of time and money because you end up doing it twice!

body parts same thing, dont fit great and have issues compared to originals.... you get what you pay for *usually

 

Whats the reason on putting aftermarket thermostat? You do know an oem is only $18

 

It opens at a higher temperature would be the issue. I ve been saying you need to use the Nissan Green coolant. This transfers heat differently than aftermarket coolant.
Get a pot of water then boil it. As its heating up monitor the temp then watch for it to open.

 

had a chain type shop put the thermostat on, why would a chain type shop ever put a pricey OEM part on there ya know? do they even have the capabilities to get real OEM? haha

 

Doesn't matter what type of shop it is. OEM is always a must for me with engine parts

 

your telling me, but to me some shops almost refuse to get the real deal parts. i almost want to replace the piece of crap now 2 days later, we will see in time how it holds up....if i over heat again because of this, its gonna be fun.

 

I just replaced mine with oem at 162K only because I did my timing chain, nothing wrong with it JAPANFTW!

 

The aftermarket t-stats are a bit different?
The springs may be bigger/smaller.
The t-stat was designed to prevent condensation on the walls of the cylinder in colder weather. This way the engine heats up evenly.
If it doesnt heat up evenly then hot meets cold causing condensation. This eventually damages the cylinder walls.

 

There have been a quite a few people that have tried to figure out what the difference is between OEM and aftermarket.

When they did the hot water testing as described in the FSM, most of the time the valve on the aftermarket thermostat did not open up as far as specified. There were also many cases when the valve did not open at the specified temperature. And in some cases late opening was combined with insufficient opening.

The thermostat is simply a temperature driven device. It opens (hopefully) and it closes. Its job is to cause the engine to warm up faster by not allowing the coolant to flow through the radiator until the engine has warmed up. The design of the engine block and cylinder heads determines how the coolant flows through the engine, controling how evenly the engine will heat up. Condensation could only form on the cylinder wall when the engine is turned off and cooling, at which time there is no coolant flow. When the engine is running, the heat created by the burning fuel mixture vaporizes any moisture that might get into the cylinder.
