Interior light

[tich]

Mornin` chaps
Seems I need your help again!.
I`ve got a bulb gone in my interior light ( the front one by the mirror ) but cannot see any obvious way to remove the light and switch cluster. Anyone been there?.
Also, while I`m here, PLEASE PLEASE is there a real clever bugger out there can tell me how to get to the blasted water temp sensor for the after glow which is apparently situated under the inlet manifold somewhere. I can`t even see the damn thing, let alone get to it!!! . Do I have to remove half the top end to get to it?.

Regards
Tich

Had a quick look. It looks like there is a little cover where the mirror stalk is. It is likely that this is removable and there is likely to be screws under there that will give access to the gubbins!

Hope this helps, sorry can't help with the sensor.

Never heard of a sensor there.Does it really exist?If so I would also like to know where it is.

According to the book thats where its supposed to be on the 2.4. Unless of course its the wrong book!.
If your good self or anyone else can put me on the trail of the elusive water temp sensor for the after glow on a 91 2.4 you would save me from going bonkers

there must be a sensor or something that cuts the power early to the plugs when its warm, on top of the manifold is a bolt where the wires are held before going to the plugs, this isnt a set-up which is used on a normal diesel engine, the power goes straight to them, so is this where it is

According to the manual and info I have seen the glow plugs continue to glow until the engine has reached a certain temperature which apparently is sensed by a sensor in the engine block somewere under the inlet manifold (according to the manual???.). I had the head replaced a few weeks ago and ever since the old girl has been lacking in power and generally doesn`t run well when started from cold until she`s warmed up. Once warm she runs like a dream.
I am assuming that either the sensor was not re-connected (which I think is probably the case) or the sensor has packed up. There may be another reason but I can`t see any other reason why.
What ever the reason it has to be resolved.

1 or more plugs are'nt working at all, check all plugs first and make sure power is getting to them

Yep! all the plugs are working on initial startup, even on the coldest mornings, its for that first 3 or 4 miles that theres the lack of power, performance etc.

nothing to do with the plugs or sensor then, the plugs dont stop on while your driving, if it was ok before the head was done its more likely either the timing is out, or the valve settings

I also believed that the plugs didn`t continue to work once the engine had fired up, which is usually the case with diesels generally, but have on this forum and other sources found out that as far as the Surf engine is concerned they do continue to glow for a predetermined time. In the manual that I have got it does contain information about this which is where I found out that the sensor was situated under the inlet manifold.

if you listen though you can hear the timer click off on the inner wing, otherwise they go off as soon as you turn the key, if plugs stopped hot while the engine is running it would burn them out in no time

OK Here is a simple test to find out how long power is supplied to Glow Plugs.

Connect a multimeter set to volts to Glow Plug Rail and Earth.Have someone start engine and you will know when power is cut to Glow Plugs.

To help cold starting diesel engines are equipped with a pre heating system, which comprimises of four glow plugs, a pre heat timer a dash mounted warning light, relays and timers.
The glow plugs are positioned directly in line with the incoming spray of diesel, when the plugs are energised the diesel passing over them is heated to its optimum combustion temperature allowing easier starting.
The length of the pre heating period is determined by the pre heating timer, which monitors the temperature of the engine via the water temperature sensors and alters the length of time accordingly.
Pre heating is started when the ignition is turned on, the light goes out on the dash but the plugs continue to heat for a bit longer, until the engine is started. If the engine is then not started within a certain time the power to the plugs is cut, preventing batttery drain and plug burnout.
After the engine has been started the plugs continue to heat the incoming diesel for a further period of time. This helps to improve cold fuel combustion whilst the engine is warming up, this improves cold running, which results in quieter, smoother running and reduced emmisions. Again this length of time is measured by the water temp sensors allowing the plugs to pre heat the fuel until the requires engine temperature is reached.

I think my plugs glow for about 10 seconds after ignition. Once its dark you can do what I did and decide for yourself. Start the engine, open the door thereby turning on the interior light, watch it get brighter all of a sudden after about 10 seconds.

How about you having a diesel leak somewhere between pump and injectors Tich, maybe something not tightened properly, a damaged pipe or bad hose connection at the pump

At last! Someone on the same wave length as me.
