trd thermostat

[old red]

hi everyone
i have a '00 camry v6, i want to lower my coolant's temperature and i want to know how much a difference will the trd thermostat make, i mean, will it lower the temp. gauge a little? will it make a difference in terms of performance?

thanks

Is the engine coolant system overheating? The engine operates best within a certain coolant temp range. Running cooler then this will result in lower MPG, increased wear, etc.

Thermostats are specified and sold by opening temp such 170F, 180F. This is on the box and stamped on the T-stat. Unless the new T-stat has a lower opening temp nothing will change.

well, the thing is i live in a place where 70 degrees is considered cold, and in summer the temperature reaches 110, also, i drag race on a daily bases, doctors orders hhheheh three times daily, so i could do better with a colder engine, also, i don't care about the "wear" thing

so, should i get this thermostat? or is just some "theoretical" crap?

A colder water temp may not produce more HP.

The Camry coolant system should be able to run within a narrow range for typically outside air temps which yours are.

However if you still want to make the change find out what T-stat temp you have (typically 180F) then find one that is lower in temp. After market manufacturers such as Stant should have ones available at lower temps.

If going the TRD route find out what temp the T-stat is and compare to what you have. You want one that is lower in temp.

i've changed mine to 170F but the temperature gauge is at the same point as before, the trd one opens at 160F

with the trd one, you'll see a slight drop in the coolant temp needle.


but in the end....it doesn't make a difference really as to what temperature your thermostat opens up as long as your car isn't over heating in the first place. the only time that a lower temp thermostat would really make a difference at all would be racing on a track- not drag racing.

But theoretically, it wouldn't make a difference either, since if you're running your car hard, the thermostat will most likely stay open regardless. What you will see a difference in that is the most important is the oil temp. But again, that should be within a working temperature as well for best performance.

So, long story short, if you can get a trd thermostat and you are willing to pay the money for one, then get one. But if you just want to keep the 170 thermostat, it's pretty much just as good under most circumstances.

i'm concerned with the coolant temp because where i live there are camrys that are a little different, "gulf specs", the temp needle is much lower then mine and the cars actually performe better in terms of acceleration, i've drag raced and tryed alot of them, they have the same 1MZ engine but it seems that the radiator and the fans are a little different, so i'm thinking maybe the thermostat would give me a little more oomph just like everyone else,

thanks though

Interesting. I was planning on getting the TRD thermostat also, thinking that it will help keep the engine running cooler during the hot days in California, but what Eye8Pussies said is right. My car doesn't have any over heating problem so I guess I won't need the TRD thermostat after all.
