Hey thr ladies n gents
Im in the process of replacing my cooling system.
My questions is, what are the pros n cons of having a low temp thermostat?
I understand that its purpose is to lower temps by opening sooner to help coolant maintain a lower operating temp.
My concern is, is it really lowering engine oprting temp? The temp gauge reads the coolant temp, in which it will be cooler beacuse it dosent spend enough time soaking up the heat(?) if thats the case, then the only way to see if having a low temp thrmostat works is, maybe reading oil temp?
Im not ASE cert or a mechanic, but if our sensors read a lower temp, wont that cause our ecu (OBD,fuel injection) to run rich?
improper coolant temperature can cause your internals to deterioate…stick to your stock specs dont invent…although i dont understand what your trying to get at?? whats your problem with the car
thnks for the reply
i dont have a problem. i was just shopping around and was wondering whats the diff, pros, and cons of having a thermo that opens @ 60c vs. 68c+ vs. OE? And (if any) the affcts it has on our ecu temp readings and how that can cause an engine to run rich (im assuming). If thts the case than is a lower temp thermo worth the install or is it like those fancy grounding kits?
We shop for oils based on their thermo properties and how they influnce performance, right?
so, if coolant controls (for the most part) our engine temp, wont that in turn influence oil performance/life?
if thats the case, wouldnt it be more affective to get an oil cooler vs low temp thermostat/fan switch or a “high performance” radiator? (if price wasnt an issue or weight savings of aluminum)
like i said b4, i kno im splitting hairs here, but i was wondering if any one thought of this?
wht do u guys/gals think?
The “performance” low temp thermostats work differently than people think. What they do is start the cooling process earlier, that is, the temp the unit opens is lower, thereby allowing the coolant to start doing it’s job. You will still get to normal operating temp for the car it’ll just take a bit longer. There purpose of these is for endurance racing and are not necessary for most builds. A parts store thermostat will do the job fine.
only time you want to run a lower thermostat is when you have a high output engine like nitrus or turbo that build up alote of heat, or autox/circut racing that demands you to keep your engine reved up all the time.
thnx ICE
i figured that out and i also belive if this up-grade is done, it should be at least paird up with a lower temp fan switch (my opinion)
i know its not somethng an DD needs but
thnx da6
i do plan to autoX and will (when i do autoX) up grade to an aluminum rad.
you don’t need an upgraded radiator, fan switch, or thermostat for autox. You’re talking about a race that lasts a few minutes at best. if in that time you’re building enough heat to warrant the upgrade, you need to look at what’s causing it to overheat that quickly. even most turbo guys don’t run these upgraded thermostats and fan switches. bottom line, imho, there really isn’t a need unless you’re road racing.
ran my boosted integra 11 psi on a t25 with a dual core half rad on a stock t-stat. no problem. b/c the teggys are obd0 or obd1 the ect is one of the critical readings the ecu has to get proper input. b/c it will drastically affect how the car runs. your going to get poor fuel economy. wash down your cylinders, listen to everyone lol stock t-stat ftw
