Engine Water Temp?

[fixkick]

I have an 82c (179f) thermostat.
I have rebuilt the engine since then.
I had a blown headgasket.
not a warped or cracked head.
it does gets up to 90-95c temp now. (bad) but under what conditions, does it do that at 100km/hr?
also it creeps up when stopped. (does it moving fast and parked sure)
I got a stock fan so looking at getting electric. no need really if fails moving, fix the moving overheat first.
I am running 50% antifreeze mix. (good)
cap is 14psi new cap, good but does it work. (hard hoses hot?, means it works ok, if not?, sure its not the caps fault but is STILL WRONG) and is job 1.

95c is wrong dead wrong, the stat is 82c how can the coolant get past that, it can,t unless rad cores are packed.
or the fan is dead, nothing at all wrong with a stock fan . electric is pain as now you need , water temp switch to run that and that adds more work , wires, fuses, and spec fitting to get the sensor , mid stream on a hose.

the correct temp on your car is 82C (180f )
the causes.
clogged rad tubes, easy work to find, with any IR gun. super easy ask.
bad stat, no its new.
fan dead at idle, but move car fast the fan is mostly useless, so if car onlyover heats parked, bingo fan.
if fan is good, and rad good.
the its a possible pump impeller, is rusted to nothing

you skipped my pressure tests. top hose hot sure, but hard when hot? 12psi pushing back at you?????? if dont know how to do that, try a good car
do that, learn to feel top hose and how it wont let you squeeze it easy, when hot, that is 12psi pushing back.
if no pressure that is a very bad sign.
5min work on a hot car,.super easy test,

most head gaskets fail not for age or fun, it fails from overheated engine.
#1 cause.
so when we cure that problem, (its a victim in most cases the head gasket)
we find the true cause, overheating.
if it does not hold pressure, then we must fix that first;. see? it means there s breach in the system if it will not hold pressure.
causes, of this breach.
1: head gasket blown (fixed) or cracks in head cooling paths, or leaking freeze plugs in head.
2: automatic trans, is that it? if A/t we make sure that cooler is not leaking AF to the trans box. next.
3; next, the block can be cracked. (freeze damage in winter )
4: rad cap bad, , no its new.
5; see external leaks, to ground, or to passengers toes on floor from heater core?

we use a rad leak down tool to see if the system is breached, we pump it up , see if it holds pressure, if not this is JOB1. finding it.
its a pressure system, and most hold pressure all the time hot...
12 to 14psi.
