I'm still confused with our PTs cooling system.

We bought our secondhand 2.0l auto second hand a couple of weeks ago.
The first weekend we had it - it got quite hot - but I shut it off before it got anywhere near the red.

After that - I found the coolant in the system to be a bit low - although the expansion tank was full.
We gave it back to the dealer - who ran it for a couple of days - it never got hot again - and they had a garage check it - and it didn't get hot either.

I put a new radiator cap on.

This weekend I checked that the fan was coming on after testing the relays. It does - just about when the temp needle nudges over half way.

When left idling the temp rises to half - then at just over half the fan kick in.

If I rev the engine though the temp drops to where it seems to normally sit which is at roughly 4 o'clock.

When driving temp varies between 4 o'clock and half - half in slow traffic.

Am I right in thinking half way is the normal position?

taking this into account - the thermostat was changed last October - could it have been a faulty one - as my diagnosis would seem to suggest it's running a bit cold??


Thanks..
Have two PT Cruisers and they both run exactly at the halfway temp mark when fully warmed up, rarely seems to vary.
