OK putting one of these on the vit http://www.ebay.com.au/itm/ENGINE-WATCH ... 1e6e35f3af Ideas on the most stable place to put the sensor? Ive got similar on the mini near a coolant blanking plate but cause it gets a bit of wind when you are moving the temp moves around a bit so I dunno how well it will work should things go bad Thinking under an inlet manifold mounting stud? or maybe the water housing on the back of the head? |

i have the same in my sierra. the instructions say to put it on a bolt on the engine coolant outlet point, so i attached mine to thermostat cover, under one of the bolts there... works much quicker than standard gauge. temp on that beeps at me (i set mine to 95 degrees) while stock gauge is just passing halfway mark |

would there not be a positive side to putting it actually on a head bolt? (while doing a head job) so that you getting the head temp, or is a bolt off the thermo housing enough? ill be doing this on mine. |

Head bolts are well down under the cam and rocker cover, not to mention a soft washer under a head bolt is a no no Thermostat housing is only going to measure the coolant temp change heating it, its not going to measure cylinder temp and all and would probably read cool if all the coolant was lost |

Lower intake stud/ bolt toward the back of the head? Been a while since I've seen a G16 so can't think of any better spots. |

Reckon the rear would run any hotter - cooler than the rest? |

Thinking less chance of wind blowing thru and upsetting reading, also furtherest from water pump. Where did your gasket blow? Did it overheat? |

Come to think of it, most head gaskets I've done (that have blown from overheating) have gone around cylinder 3 or 4 (3 or 6 for V6's) |

I run one of these on my zook. sits under a thermostat bolt at the rear of the head (gti). I rely on it moreso than the dash temp these days. Sits at 82-86 degrees almost constantly so my overheat alarm is at 90. Has been a lifesaver during a total loss of coolant (lower radiator hose split). The only frustrating feature is the overheat alarm will usually sound for a while when you stop then restart the car due to heat soak. |

when you lost coolant, did it start to read higher quickly? did the normal temp gauge read cool? Just curious what it all did |

Normal gauge showed no change, watch dog hit the alarm then up to 100 in under a minute so a good warning for me to pull over and check. Having the display in clear view, you get used to what's normal and soon jump when something changes |

Same as the one Royce linked too. Was the first thing I added to the zook after having overheating issues in my old one. After ~5 years of using it, multiple drownings, filling it full of water etc it still works flawlessly and does exactly what I ask of it. Can't say anything bad about them. |

sweet, how big is the gauge? |
|
| Author: | mnemonix [ Tue May 22, 2012 10:41 am ] |
| Post subject: | Re: Engine watchdog - Cylinder head temp |
At a glance, Display is ~ 30mm H x 70mm W x 50mm D, plus mounting "wings" for screws on one side. You could flush mount it in a dash somewhere if you were tricky. I've got mine mounted under the dash/glovebox. It's obvious enough to catch my eye when I want to check temp while driving, but not glaring in your line of sight. |

how did you go Royce? did you get it and is it working effectively? Mitch |

yeah seems to be pretty consistent, I guess I could dump the coolant to test it but somebody else can fix the mess Interesting that it shoes a few degrees hotter at 2500rpm in nay gear, I think where I have it attached it might be reading temp from teh EGR, ill have to plug my thing in and see when the EGR is on |

| Post subject: | Re: Engine watchdog - Cylinder head temp |
thanks for that, where did you decide to mount? rear of the block or thermostat rear bolt? |
|
| Author: | royce [ Tue Jun 12, 2012 6:49 am ] |
| Post subject: | Re: Engine watchdog - Cylinder head temp |
its on the rear upper inlet manifold bolt, closest I could get to the chamber side of the head, I think anything on the high side of the head might be slow to react as the head is quite hollow |

would it be worth finding out if its a NTC or PTC probe and getting wone that screws into the standard temp prob mount and getting one of the hose temp fittings (super dear auto things) as then the probe is in the liquid and has direct contact? |

Wouldn't help if there was no coolant to contact for a temp reading. |

tru, but it would give an odd reading still |

| Author: | royce [ Tue Jun 12, 2012 7:45 pm ] |
| Post subject: | Re: Engine watchdog - Cylinder head temp |
The idea of it is a separate measurement of engine temp, measuring the metal itself rather than coolant, so if there is a problem with the cooling system this will alert you to it There are already plenty of ways to measure coolant temp |
