I know Toyota's design for the temp gauge is to have the needle sit horizontal at idle when fully warmed up. Ours however is a bit higher especially when driving (which is the reverse of what is supposed to be).
Fan seems ok, new radiator is full of anti-freeze, new hoses recently done.
Would bad axle CV boots cause some heat build up that's significant enough to increase engine temp at speed?
Can somebody also describe the process of start-up within the engine bay? I hear a sloshing sound that's within a given frequency (like every 4 seconds, barely noticeable), on a cold start (like overnight). Checked a while ago when starting a mildly warm engine and no sloshing sound is heard.
I'm leaning towards a thermostat. But what if it's not that? I'd like to hear alternatives as a back up plan. Thanks.
I believe your right when you said thermostat. It would be partially stuck closed. It's not uncommon for this to happen since you have an older car, but I need a new one cause mine is stuck wide open

Nope, CV boots cant cause it.
YEah I've heard some sloshing in mine, didnt have a problem, however I did have a blown headgasket at the time. Then when we fixed it, it did it few times when there still was some air in the engine, then it stopped doing it.

Would that mean that the engine would run cooler a few minutes longer after starting?
I had my car serviced for overheating. The radiator fan wouldn't turn. I replaced the fan myself but experienced some squaking noise after so I took it to the shop. They cleaned the engine block water jackets and they also replaced the A/C compressor. Now it runs rather cold (one tick below horizontal). I have no problems with it so far. In the highway, it runs in 1/4 of the temperature gauge. It only goes horizontal in daytime traffic.

Unless you have some extreme weather conditions your car should always run at the same temp. If the temp varies you have a problem, check your thermostat works and that your fan switches on.
Is it possible to have a clogged radiator this soon? Just replaced the radiator last year bec of a leaking transmission cooler line (from the radiator).
It's quite cramped under that distributor cap (where the T stat is, I presume?). Any advice you guys can throw at me to make life a bit easier?
maybe not enough airflow to the rad? not sure about the sedans, but on the coupes we have plastic panels undernieth that keep the dirt out and make the air go where it's suposed to

Was thinking of this too, but I'm sure those plastic pieces are in there (intact). The radiator is new and there's no obstruction at the front save for the large bumper and rather small grille slit at the bottom center.
By the way when I noticed the temperature, the exhaust manifold heat shield wasn't there. I just installed it last night after digging it up. Could it be simply a matter of that small piece of metal?
What makes you think its not the thermostat, it is the most likley fault. (especally if you have a newish radiator)
There cheap and easy to replace anyway.

Well I was just ruling out some things (and considering other possibilities). Another thought would be to make it easier for newbies to search in case they read this.
Just thinking fast-forward. Will get one and install it, hopefully it's as easy as installing one in my car (non-Toyota).
Well I can be going any speed highway or not, and my temp gauge is either barely above C or halfway to normal. Never normal, never hot. If your car is hot and if it's the thermostat, it's stuck closed a bit. Like I said, they're cheap so you've got nothin to lose. Let us know what the deal is!
