T25 with a dodgy temp gauge and a Peugot Engine.....

[tjoynson]

Hi all,

Interesting one. Just picked up my camper and didn't think the temp gauge was working as it never rose much. It stayed in the white column on the left, pretty much in the middle for most of the trip but moved to the upper edge when hitting some hills.

Low and behold, the water coolant level went from hi to lo from Plymouth to Bristol.....

I really want to be able to keep a good gauge on the engine temperature, but as the engine was changed out for a Peugot 305 1.9D, I think it's not working properly.

I have absolutely no idea how to even start on this problem to get it all working properly. The temp indicator is the original for the T25.

Any ideas on what to look for?

although this is a tech question, perhaps you will get a better response on the alt engines forum, down a bit from here........

honestly speaking, i would be finding out the temp the engine should run at, checking it is( household temp trobe) and them noting where that is on the gauge......... (normal on a t25 gauge is anywhere between the two white boxes, so basically the centre 3/4 of the display) more important is where did the coolant go......

what has probably been done is the vw wire has been connected to the pug senderunit!
mine did exactly as you described when i ran mine like this.
what i have now done is drill/tap the pug sender and fit a vw one so the gauge reads correctly!

Hi all,

. . . didn't think the temp gauge was working as it never rose much. It stayed in the white column on the left, pretty much in the middle for most of the trip but moved to the upper edge when hitting some hills.

This used to happen on our vw engine . . . until the thermostat was changed. The old thermostat was opening way too soon, because the spring had lost its strength so was opening at the first sign of any pressure in the cooling system.
