I already diy built and installed that "water temperature alarm" in my Mitsubishi Lancer EL 1996 after my 4G13 overheat and emitted black smoke. I've called it "Coolant Overheat Alarm". When engine start to overheat Red LED will blink together with beeping audible alarm. It's a must have for old cars.:proud:

Nice DIY!! so at what temp do it sound the alarm?

Nice DIY!! so at what temp do it sound the alarm?

I don't know the exact temperature. What I did was to compare the Normal temp voltage of +5.1V from the coolant sensor ( Intake manifold sensor ). I have 3 jumper or temp voltage selection switch ( 4V, 3.6V and 2.4V was the highest temp voltage ). I set the my circuit voltage comparator to +4V. If the engine coolant or water start to overheat. The +5.1V will drop down below the set +4V and the circuit will be triggered and blink the Red LED with beeping sound. I assume that Temp Gauge needle should be above 1/4" from Normal Temp Needle pointer position when engine start to overheat and trigger the alarm. I've installed a smaller speaker ( 1/2" diameter) so that it will not be annoying.

The water alarm sensor was triggered before when my radiator fan stop due loose radiator thermoswitch connector.. But I forgot to to see the temp needle pointer position. Because I have to stop immediately due loud annoying sound from the big speaker 3/4" diameter. The alarm really works.

papagoines..if u got time maybe we can have TT. i'll u show the difference between NRG and shadow.

 

[papagoines]

Rleo6965: Nice one... if we can get a good thermometer to really test the output, maybe we can get the alarm to sound off at temperature that we really one

FYI, my engine normal running temperature is indicated at half of the oem water temp meter....standard with all Daihatsu Mira L502 turbo...


MKMD428: Appreciated it bro... already seen the diff wif my friends car... that's why deep down always wanted shadow...

just that nagging feeling at the back of my head that should save more to get JDM...

but then another nagging feeling that fear my car wiindows smashed

...dammit scumbag brain

 

[MKMD428]

shadow < JDM < scumbags / thief

quite hard to sort it..
think of any passive measures that might deter possible car breakup.
then it should be fine kot..

 

[amrancharger]

well..lets put it this way...if u can afford a japan gauge..go for it.
now even standard cars is a target for thieves.
i tink someone post somewhere about 2 wheels being stolen frm a waja..

 

[papagoines]

MKMD428 & amrancharger: Yeah! want to place at inconspicouos but need to be seen... :hmmmm:

been using NRG water temp gauge for almost 1 year now, so far so good. it lights up at 98 degree C and managed to save my engine once. for the price i think it is 'ok' la. how long it will last.....let's see.

 

[facegreen]

Defi Original is BEST but Pricey.

Shadow is best alternative brand u can use,

SORRY NRG & AUTOGAUGE are just rubbish, either sensor always spoilt or Gauge Malfunction.
(Do not waste money on both brands above)


Cheers

Bro,
NRG Meter giving me lots of complaint from customer. Sold 10 , 7pcs sensor K.O.

Pricing is only a bit cheaper than Shadow, why take the risk?

this is just my point of view where i experience many cases.

My friend just called me informing me that his 4G15 cylinder block was punctured by broken connecting rod due to engine overheat. His mechanic removed the sensor wire of coolant overheat alarm sensor wire that I installed. The mechanic did not inform him that he disabled the coolant alarm. Very bad news from my friend.

 

[papagoines]

Thank you all for the feedbacks.... believe me, every opinions count

Although it maybe a while for me to purchase the said gauge due to current financial issue...

my list so far are as follow (the most realistical la) for brand new gauge

1. Shadow (due to price + good feedback)
2. Defi (might take longer time to purchase)

but please do keep the discussion open for the benefit of others like me

sorry for his losses

Here's the picture of cylinder block with big hole damaged by overheat due to stuckup radiator fan.

Goodbye my friend's 4G13.

OMG...that looks like a puncture wound after an attack by a predator alien....

 

[D-G92]

How about Drift brand meter??

Do anyone use this brand meter before??

 

[MKMD428]

No audible warning for sure.

 

[Rleo6965]

Audible was warning was important to be able for you to immediately stop your engine. Prolonged overheating engine will cause damage to rubber valve seals, oil seals which result "leaking" inside the engine.

Yesterday I made the silliest but potentially dangerous to my engine... not to mention to my family

I was at my mum's house @ kajang. Being the paranoid me, I've check my radiator before departing to my house @ Ampang via MRR2.

The mistake was, I forgot to put the cap back on :stupid:

Realized when nearing pandan indah (before the u -turn flyover) when me and wifey smells something off, like a burnt coolant.. before this when the engine overheat, we detected it because the air-con felt hot and smell of burnt coolant...

looking at the oem meter shows the meter fluctuate from middle point (normal in a turbo L5 engine) to nearing redline (when boosting)... but never reach the redline...

parked below the u - turn flyover (got a bus stop there), open the hood and I saw the steam rises

amazing thing is, the radiator cap sit still on the battery throughout the journey w/o falling off during the rather bumpy ride hehe

luckily my friend's was nearby and I can ask him to bring distilled water to replenish the radiator... up until today, no issue, whether engine or temperature

no audible alarm, but very good smell alarm
