Re: Temp Gauges for Volvo 2030

continuing the digression. This is a link to a code decipher for glow plugs. Using this information I purchased $8 glowplugs for my 2030, and Volvo wanted almost $90 for the same.

My existing in boat VP2003 uses 1/4" NPT for water & 1/8" NPT for oul because I added gauges & also kept the alarm senders.

Is there a metric pipe thread? I thought everything was NPT worldwide,except UK, who kept BPS with seal rings.

Have sort of answered my question about existance of metric pipe threads.
Apparently,they are out there in places, along with BSPT/BSPS.

Example, American oil pressure senders read 240 ohms @ 0 psi and European senders are 10 ohms @ 0 psi.

If you want to buy loose VDO senders to drive your VP gauges, make sure the senders have European resistance values and that they match the pressure and temp range of the gauge.

The 2030 sender thread sizes are:
temp- 18 X 1.5
Oil- 1/8 pipe

DougR
So I happened across this thread while searching for a sending unit for an MD17C. Same part number.
I just replaced my gauges with Faria gauges, (hour meter, water temp and oil pressure). The water temp gauge was reading hot all the time, the hour meter didn't work and the oil pressure was fine.
Anyway, the new Faria gauge reads 250 deg too so I took out the sender and immersed in boiling water @ 212 deg and low & behold, the gauge still went to 250. I thought a gauge was a gauge was a gauge. So now I guess I need a sender to match my gauge. $90 Cdn for a Volvo? I don't think so Tim!
So those threads in your answer above 18 (threads/inch) X 1.5 (1.5 what?)

Not meaning to hijack the thread but now we know that both our engines take the same sender

Re: Temp Gauges for Volvo 2030

Different question, although many here have a VP. I have a VP MD2040D, when running the tach just dies, everything else works. Have put a new tach on,VP, very expensive. The alternators have been rebuilt at different times for other issues, no change. Suggestions on this problem?

Re: Temp Gauges for Volvo 2030

So AD28 thanks for the post can you tell us the part number or is it the one in the example?

Your VP 2040 is a Shibaura & is same as Perkins M series & several land equipment mfgrs.

Quite sure DougR meant M8 x 1.5 which means a an O/D of 8mm & a thread pitch of 1.5 threads per mm of length. Approx. 5/16" UNF in appearance but definitely not interchangeable.

Thanks, I should have done some tests before buying those gauges. I'm not too happy about the faria hour meter actually. The damned thing measures a 72 second hour. 20% error!

Re: Temp Gauges for Volvo 2030

MD 2030 temp sender threads are 18mm diameter X 1.5 mm between threads. Sorry I failed to be clear on this. ( metric threads are measured from the tip of one thread to the tip of the next thread, unlike American threads which are usually stated in threads per inch)

This sender can be seen by following the link posted in response #14 of this topic.

[Edit: best to start another thread with your question since its unrelated to this one]



How is your alternator regulated (internal or external)?

Some external/smart regulators will effect the tach.

Is there still output from the alternator when the tach dies?

WOW! For once everything went off without a hitch (almost). I'll try to make this short. I've had a problem with steaming exhaust and a gauge that read 240 F. I knew 240 f was a false reading because I shot it with a laser temp gun. Fast fwd, I finally decided to replace my gauges (other were toast too). Assuming all gauges were the same, I bought Faria temp, hour meter and oil pressure gauges. Then found out about the difference between American and European resistances. So then needed to change the temp sender. Thanks very much for the advise on this one. Turns out that the local Volvo dealer had the right unit and it was only $25 CAD.
All is good now. We motored around the island today at a steady 150ish degrees F.

Thanks again guys!

Apologies DougR. My comment M8 x 1.5 is wrong.
You are correct. Temp sender is 18mm x 1.5

Re: Temp Gauges for Volvo 2030

Just replaced the temp switch for a temp sender on my MD 2030 C and the size was M16 x 1.5, (not M18 x 1.5). Bought a VDO sender to go with my VDO huge.
