Posted: Sat Mar 23, 2013 14:51 Post subject: New Sensor locations, Help Please |
|
|
I'm trying to work out where to fit 3 new sensors, water temperature, boost pressure and oil pressure:
I think the boost sensor should go into this pipe:
I think the Oil pressure sensor should replace the stock one here:
I have no idea where the water temperature sensor should go.
Can anyone confirm if my guesses are right and also where to put the water temperature sensor?
If you've got photos that would be great because I don't know what most of the stuff in the engine is for/called
Cheers

Can't help with the oil and boost,the water one might go in place of the existing Deli one,its situated where the top hose goes into the top of the engine.only other suggestion is to get a plumbing t piece and some hose tails to fit either end,and fit it on the heater matrix pipes behind the battery.
or measure the resistance of the probe,then measure the delis temp probe and if they match take it off the delis temp probe.
sorry Can't be more help! |

Thanks Lexis, doesn't that mean that the blue wire in your first picture is the water temp sensor?
Also do you know if I picked the right hose for the boost sensor, it occurred to me that the one I was looking at might be an oil feed and I wouldn't want to cut that. |
I've just fitted an aftermarket digital temp gauge as the o.e temp gauge is bobbins i just got a 36mm adaptor that fits in the top hose , simple

as for the boost gauge sensor you will need a tee piece so it feeds the sensor and also signals the boost pressure to the injector pump diaphram .
i would also use a tee piece for the oil pressure sender unit as well otherwise you will loose the oil pressure light .

I suppose I'll also need to work out what the correct readings are for each of them
Rick, am I on the right track with the hose for the boost sensor? (I've got a t piece for it) _________________

It will be, they have been designed that way for some time now. |
'Modern' gauges essentially have three positions. 'cold', then 'normal' where the needle will read in the middle of the gauge as long as the engine temperature is anywhere within the 'acceptable' range, and then 'hot' if it actually IS overheating. This is why the temperature can suddenly shoot up - one minute you look at the gauge and it's fine, the next it is in the red. The engine temperature has been slowly creeping up, but the gauge doesn't respond until it hits the 'hot' level.
You see, people were complaining that their cars didn't hold a constant temperature, and that the engine got hotter when towing a heavy trailer up a steep hill or in standing traffic or whatever. How dare their car overheat! For most of the car buying public, ignorance is bliss. |

As Rick says, top hose for coolant temperature sender. There it gets the coolant straight out of the head so is the best spot for the earliest warning of a problem:

Defo sensors. One at least must be for air-con (to shut the compressor off if the engine gets too hot).
Anyway safe to say that none of the stock sensors should be replaced in order to fit an aftermarket temp gauge as they all do at least one important job beyond just showing the temperature on the dash gauge. Highly recommend the 36mm adapter in the top hose route. |

if I'm being honest here before taking the top hose adaptor route i looked at drilling and tapping the rear of the head as this is the point were the temperature tends to be higher but after giving it some thought i decided against it mainly due to access and the shortage of a good location for the sensor .

You could always fit your temp sender the ‘professional’ way like I have done, into the top hose, blob of TigerBond and an extra clip just in case.
It works though. :D _________________ Artificial intelligence is no match for natural stupidity.... |

Took a picture of the two sensors whilst I had the inter cooler off, thought it might be helpful to someone:

I've got no choice but to get a 36mm adaptor for the top hose as none of the adaptors for the sensor fit in the existing water temp gauge hole _________________

So it wasn't losing the signal to the glowplug ECU or overdrive that put you off doing that than? |

I have piped in a 36mm adaptor to the top rad hose with a water temp sensor and the digital gauge inside is wired up to power, but I can't find any quick routes through to the engine bay for the sensor wire. I did see a loom down near the driver's right foot going outward through a very tight rubber seal and forward inside the wing. What did others here do? Thanks for any help. |
