Instrument question with 240's
Hello all,
I have returned to the wonderful world of the Volvo, I used to have an '80 240 when I was stationed in England a good car. And a bout 4 weeks ago I bought a mint '92 240 one owner with 130,000 miles on it. Now the car is super clean and the wife just loves it! AC blows cold and the only Quird I have noticed is the temp gauge will got to just under the hot line and then drop back to the middle. I don't think the car is actually over heating.
Also, I wanted to up grade to a full inst package, would love a tach where the clock is, and a real oil pressure and an alt gauge.
So my question is what instrument clusters would just drop in? what years specific? how big a hassle is changing out the gauge package?
Thanks and God bless.
Mike

I've had a sticky thermostat do that, temp gauge climbs up to almost too hot, then the thermostat opens late, and it cools back down to normal.
BUT.. on the volvo 240/740/940's after some point in the mid 80s, the temp gauge on the dash has a 'compensator' circuit designed to keep the needle dead center if its anywhere near normal operating temps, and only read high if its really hot. this circuit can crap out with age and cause bogus readings. on middle run 240's, the circuit was on its own separate little card plugged into the back of the instrument panel, and you could replace this with a jumper and get a linear reading temp gauge (where it will go back and forth around the middle range with driving conditions). however, on late 240s they dropped the separate board and integrated the circuit onto the main instrument panel circuit board. all 740/940 also have this integrated onto the main board. I've toyed with trying to trace out the circuit on my 740T and hack around it but I've never gotten up the motivation to actually try.
