Hi

I've got above car recently with temperature gauger showing only 70. As a friend is mechanic he had a spare second hand sensor (4 pin blue square) which he fitter in but was showing still 70.

Now, I've bought a new one thinking that both of them are faulty. Still 70 degrees

1. Could it be the thermostat - stuck open - even so how come car never warms up above 70? Also, it sits at 60 for a long time then jums to 70 which means thermostat does open

2. the temp sensor - it feels very loose inside and easy to move and twist. No water leak tho - is that normal?

3. Since old CONCERT car radio was in 'SAFE' mode I've replaced it with SONY. Got all 4 speakers working but no AM/FM radio? Antenna is connected. Is there an antenna amp, where is it and how does it get the power from radio. The only power out from radio is connected to rear speaker amp.

Any views on this please
Thanks
