I have a bit of a strange issue with my Volvo 340 (1.4l), a month back I started my car it sounded like a squeaky belt, however it stopped after a few meter, on the way I noticed the engine wasn't reaching it's normal temperature, when I was stopping the temperature was increasing again to normal etc. So my thought was it the thermostat, change it and it was alright up to now, again the same issue, a very, very slight squeaky noise (stopping after a few min again) and believe the thermostat failed again. The cooling system was before clean, and I cleaned and refilled it before, so I son't believe it's the issue... can't believe it's the water pump ether (but not sure). Has anyone an idea what the issue could be? Thanks.

I have about 7 or 8 340 temperature senders from 1980 to 1990 cars, single and twin connector ones which i have changed , upon cutting them open there is corrosion where the spring terminal presses on the temperature sensitive pellet in the bottom of the sensor ..hence the higher resistance/lower needle reading than should be. I am wondering if the cheap E-Bay sensors work?

I had an Isodrop sensor (single terminal) for a Smiths that worked well, but managed to find a NOS Smiths two terminal one so the gauge would read correctly.
