Got to side with Wayne on this one.....pyrometer first, water temp. gauge next. Kinda like watching a tennis match...your eyes are constantly moving from gauge to gauge. ( Its a talent most other drivers don't have).:)

This is very similar to the chicken and egg argument.
Either way something can end up "fried" is you are not careful.:)

Man we could bat this one around all day.:)
1st.....Toyota builds and installs an engine that is notoriously un-reliable.
2nd....Toyota builds and installs a water temp. gauge that is notoriously un-reliable.
Installing a factory pyrometer would be Toyota's way of admitting that they had screwed up which is something large corporations have a hard time doing.

Additional water temp gauge gives very early readings of imminent disaster and often will save the engine; providing the owner/driver reacts of cause.

As for an egt?? :popcorn:
 
you still have not answered my question, how many Pyros have you installed in your vehicles?
do you have any idea what a pyro does?
do you have any idea how fast a pyro reacts to heat?
do you have any idea how fast a water temp sensor reacts to heat?
do you have any idea how the two relate to each other?

sheesh, children these days ...
 
Okay, lets try diplomacy......install both the pyrometer and the aftermarket water temp. gauge the "sameday".:)

I have temp, boost and egt installed.

The topic here was which to install 1st. I am stating water temp.

If you can't accept that then its not my problem. I still will install water temp 1st.

;) Thats how mine went. Had a boost gauge installed 1st.
 
and if you can't see that the pyro is a more accurate gauge of what is happening inside the engine AND are still recommending a water temp installed first (which responds to heat MUCH MUCH slower), even though you are running a pyro, then you are a fool and only a fool will listen to you.

it really is that simple.

and as you so eloquently stated "that is not my problem".

Then you may want to be kind hearted and tell me all about pyro's cos I really dont understand.

I know about the temp gauge alright.

this better?
Actually you don't disagree with me. You think you diagree with me but you are mistaken. :crybaby:

You're simply experiencing an illusion caused by the limits of your comprehension and understanding. If you fully comprehend both the request for information and my recommended solution, you would agree with me. ;)

so what appears to be a difference in opinion is just you wrestling with your own incorrect thought patterns. :o

There is no reason to get the rest of us involved in your misunderstanding the proper answer.:doh:

Now WTF did I do for that?:p
 
the extended version of "goofus" ...
don't take it personal, i insult even those i like.

so, seriously, you don't understand how a pyro works?

Seriously, no I don't.

I have one installed and see it going up and down quite responsively.
 
i will use laymans terms (since i don't know the correct terminology anyway)
the pyro reads the heat being generated from the cylinders. the harder the engine works the more heat being expelled. climbing hills, towing, passing, bucking a head wind etc all cause the engine to work harder. since the pyro reads air instead of fluid it can respond extremely fast to changing characteristics of the engine, showing you what is happening inside the engine in REAL time and not delayed time.

the coolant temp reads the coolant, the coolant is heated by the castings around the coolant, the castings are heated by the combustion of the engine. the coolant temp can take minutes to react and register on the gauge. the pyro takes seconds.
by the time the coolant temp gauge reads the change in the engine temp the damage could already be accomplished.

i have seen the pyro read 1400F and the water temp not change. i have seen the water temp read in the red while the pyro is already back down to 600F. the two work completely independant of each other. you need both gauges to know what is happening.

hence, if you are to install just one, i recommend the pyro. it really changes how you operate a diesel. the myth is diesels LOVE TO LUG and nothing can be further from the truth. diesels generate tons of heat when lugging. diesels can expell heat easier and more completely if they are reving at a reasonable rpm.

if climbing a hill and the pyro climbs to an uncomfortable level then drop a gear, (speeding up the engine) and watch how fast the pyro drops back down.

and that, kids, is your leason for today.

cheers and peace.
 
Let me make sure I got this right....the cylinders are the do-dads that move up and down and cause the engine to vibrate which in turns causes those ripples at the top of the coffee cup.
This tech stuff is difficult for me to understand.:) ......1978HJ45
 
nah, you fail.
class is out till tomorrow.
in the meantime ... back of the class Junior

That's pretty much what I heard from every teacher, grades 1st through 12th.:)
