Strange cooling fact (Subi VS stock)

[ftp2leta]

If you look carefully at this image you will see that I'm using a stock 83-85 1.9L temp sender in my engine conversion, center of image right beside the Subi sender.

I was bleeding a van yesterday and (fully empty of coolant) so I had top play around with all bleeder.

The OBD reader was showing me 205F wile the VW gage (in the van) was slightly over the red light. The rad fan should normally kick at around 200F and stay on long enough to bring it down to 187-190F

So I did some test, I boiled water to 212F (100C) and dip a second sender into it, the VW gage/dash was not even showing 3/4.

I have tried that with 2 different van/cluster and got about the same result.

Meaning that if you hit the 3/4 with stock engine your running to hot.

When the van was bleed properly the low speed fan was kicking between 199-201F, the VW gage was showing half on the red light.

I'm not trying to say anything special but that struck me yesterday.

Cheers, Ben

"New" senders or old ones?

It can well be that the new ones are off.

Those new $2 - $6 ones do NOT inspire me.

I kept a tin can of old ones and many have different part numbers.

You have to measure them and compare against the charts.
