Water temp gauge

[probedb]

I had Pip install my sensor while it was in for a service and he said it won\'t show a reading till the thermostat opens. Is he wrong to have put it there then?

Here are the instructions on how to linearize the stock temperature gauge for the FD for anyone who is interested.

I\'ve currently uploaded it to my own web site, but if people are interested in this, it may be worthwhile uploading it to the MRC website with a sticky thread.

Hope this is of interest to people.

Interesting reading

Justin, a bit off topic and not meaning to be horrible, but is there a reason for your posts always being in bold?

Fish

makes for an interesing debat to be honest

reasons for putting mine where i did

1 - i bought the gauge and it was cheap
2 - it was the only real answer
3 - surely some reading is better than none
4 - both my stock gauge and after market read a temp
5 - how can the top hose be showing a reading of 82 and the engine over heating .. that sounds like a water pump failure and you would be reading static water

JUST out of interest , is the top rad hose reading water going into the rad or water coming out ... this gives you two sorts of answers

1 - if it reads GOING IN .. then this is the temp of the water in the engine , and not cooled , so if this is HIGH then your engine is very hot aswell - time to pull over and pray to the rotary gods
2 - if its water COMING OUT THE RAD .. then this is the temp of the water that is feeding the engine .. so if that at a normal temp then so should the engine ?

ive changed the thread title aswell - it was really annoying me

[Efini82]

riiiiiiiight, think i know where i should put it but still wanna get it right so...


1)could just replace the standard gauge with the new one i have from the standard sensor location but somethings still niggling me about that....

2)in the themo housing by drilling and tappin like the guy on here

says to do seems like the good place, but as people have said (and makes sense),if the t-stat is knackered then i wont know (pretty thorough instructions tho)

oh bu*ger. where shall i stick it (dont tempt me! and it sure as hell aint up mine...)!!? someone just tell me please  :flamed  

my heads hurting :3Confused .long day at work with some headcase who wouldnt shutup.!

PS why did did u change the thread name? wot did i call it? not that i care  :p :Grrr

[grinder]

you called it water temop gauge

the O in temp was really buggin me

to be honest matey - stick it where you feel comfortable - I did , and i havent lost sleep over it

we can argue this over 10 pages ,  at the end of the day its YOUR car

i put mine there cause i wanted to and it gives me a reading , i know when the thermostat has opened , therefore its at an operating temp

im just waiting for you next thread ... OIL TEMP GAUGE !! LOL

now before you say , mine is going in a housing plate under the oil filter , this may or may not be the best place as you can tap it into the oil cooler banjo bolt thingy - im not , its going in a plate

Efini, yes, its your car, put it where you want it.

But, for me, after the thermostat is a cr4p idea, sorry !

:-)


Stu, there is no oil thermostat ( there was on early cars ), the oil is pumped everywhere all the time, so , anywhere in the system should be fine. Mind you there are pressure relief valves, I guess its not pumped everywhere all the time. Without investigating it, though, I guess it would always be pumped through the filter, so that should be a pretty good place for it.

5 - how can the top hose be showing a reading of 82 and the engine over heating .. that sounds like a water pump failure and you would be reading static water?

Answer - because the thermostat is stuck closed - or, as you say, the water pump has failed, which, actually is ANOTHER reason why putting it in the hose is a cr4p idea !!  :-)

[Efini82]

how rude!!!! :flamed   i wasnt gonna ask about oil temp gauge (and the O was a typo, not me being a flid)

right, im gonna try replacing the standard gauge with the new one.


cheers

i was only posting in yest matey

when you do it - dont forget to take pics so that people can see what you are doing

I\'m ill at the moment so Im probably being thick because of it, BUT:

If you have a standard gauge along with an after market one which is plumbed in to the top hose, You would imedeatly know if the thermastat had faild shut!!
basicaly from my experiance with my FD driving in arctic  conditions the other week, the thermastat opens about 1/4 - 1/3 of the way up the standard gauge, so basicaly if your second gauge doesnt show a reading by this time your thermostat has faild shut!!
Also thermostats dont open at 80ish degrees then fail & shut (from my experiance!!!)!!!!

The same process would apear if the water pump fails........ but even then the stock gauge wouldn\'t respond as the warm water isn\'t being pumped to eather of the sensors!!!!!!!

Thats my opinion,

I think it was good to change the title because if people do a search, they will find this thread.

Mind you , the more people find it, the more flak I will probably get !

:-)

[grinder]

he he he !!

mine being an FC the gauge sits flat at 90 degrees , so if the top hose gauge doesnt show a reading after a few mins of it being in that position i know i have a problem

i also make sure i give it no heavy right foot until the top hose has a reading ( and then i usually wait as oil will take longer to get hot ) - thats why i want the oil temp gauge in aswell
