Fitting Gauges

[nesty]

I want to fit the below gauges to my 1.9 Holdsworth. (I haven't brought them yet).

Water Temp gauge (Additional)
Oil Temp Gauge
Oil Pressure gauge

Can anyone give me a link to fitting these on a T25.

Try and get hold of a copy of http://www.vwcamperandbus.com/blog/keep ... us-alive-3

It had a guide for fitting after market gauges.

Why oil temp
have you got an air cooled engine?

No got a Watercooler. I suppose on a Watercooler a bit pointless?

Hey it's your money

Oil pressure gauge is best
I fitted a mechanical one as it's cheaper and a bit more accurate.
What that does is give an early warning to damage.
I got a PSi gauge as the increments are better.
Engine sits happily at 45 psi at the tappet gallery @3500 rpm
and 18 psi @ 1000 rpm

I would be fittng a ammeter and or a Voltmeter aswell to keep an eye on the alternator and it's ability to run the toys in the cab whilst driving

Demon Tweeks sell all the kit.

Hi Kev

Many thanks for that. I already got dual Voltmeters in the car. I got 2 of those LCD displays on ebay that cov-kid has. They tell the state of my starter and Leisure battery set up pretty well.

My Water temp gauge playing up and I wanted a more accurate feedback. For the Oil pressure I normally work in BAR though!

OK so I'm old skool I can under stand a 2 pound bag of sugar

ok. Btw Kev do you know where the best postion to mount the probe holder for the water temp gauge. I'll have to cut into a water hose won't i?

Depends where you want the water temp taken... after the rad or from the cylinder head

Whats the more accurate reading then?

[kevtherev]

It would all be accurate but whether the value read would have any significance is more important.
So if that is the case mounting a sensor as near to where the rad fan switch is.
And perhaps a further sensor to montor pre stat opening temp, on the bypass hose.

I might go with the Oil Temp as well. That way gives another indication as well. I do love a bit of dials!

They'll both be "accurate" - for their location, and it's not really "absolute" temps that you're after, but advance warning of any rise in temps. After the head will be the warmest point in the system, after the rad the coolest. You'll have a faster reaction to any rise in engine temp from the head, but a faster reaction to the efficacy of the rad from the return pipe. In addition, the rad return won't tell you anything useful whilst the 'stat is closed, since no hot goes to the rad then.

So, basically, what do you want? In reality, I suspect the right answer (as ever) is "Which'll be easiest...?"

[nesty]

Ok cheers many thanks. Well easyiest if possible. Though as you say it's just a precaution to address any probs.

My temp gauge on my 88 DG is erratic so I bought a VDO temp gauge and sender from JK. My local garage cut the sender into the metal water pipe in the engine bay - not sure how wise that was but the gauge sits at a constant temp once the stat has opened, so hopefully I'll get reliable warning of any temp rise.

Now I must follow the advice in an earlier post and see if I can fix the erratic readings from the original gauge!
