Hi

I just installed a 3 clock magnolia gauges (off rover) and found 1 problem regarding temp sender hole.

currently the temp gauge is not connected as I got the car with VDO gauge which I think is not working properly as well.

Now do I need a Rover temp sender unit for the magnolia gauge to work properly? anyone knows a part number?

I tried GTR102 and the tip is too big for the hole now I had a look in the hole for the sender and its quite clean and no rust or broken off thread/sender stuck in there.
Just the tapered look like wide diametre hole that goes in to a smaller diametre hole.

here's a pic (blurry), the lower unit is a VDO one



here's another similar size unit that wont fit in the hole in the head


engine is an A series 1275cc from 1100S

Anyone heard this problem before???

Cheers

anyone please?

dont know about part numbers but i wasnt aware that any of the head castings changed or used different sizes as far as temp senders go!! it shud fit, it will look a little too big but have u tried screwing it in and seeing what happens? kinda a going out on a limb idea there but as long as it goes in and doesnt leak it shud work!! how about taking one out of a mini or metro in a scrap yard if u think you have thw wrong part.

I tried already the tip is too big
I'm been told by a mini guru that it should fit as well
but I put a flashlight to see if there's broken stuff in the hole but its clean as factory look, like half the normal length thread and tapered hole that goes in for a smaller diametre sender unit tip.

hmm. try fitting one thats already been on a mini or metro then, thats all i can suggest. failing that drill out the hole on your cylinder head and see if u can get the nerw part to fit.

[fikus01]

try and post a clear picture of your cylinder head/.

If it doesn't fit it's the wrong part, so i wouldn't bother drilling it out to take a part that's not meant to be in there anyway, just find the right part for the job.

Is it possible someone has already drilled the hole to take this thing?

[Bungle]

the tip normally just sticks out into the water jacket under the thermostat housing

could you drill the head into the water jacket ?

I tried taking a pic but its too blurry
might drain the coolant 1st to get a better view as well

I've been advised to just drill the hole bigger, I'm just worried that I might wreck the threads by accidentally hitting it with the drill and if that happens its going to be a bigger problem...

[Razor]

can I just get an aftermarket VDO electrical temp sender and put a resistor or something on the wire to match my magnolia gauge?

[fikus01]

see what resistance it runs on but i gues you could do that unless its too high!!
