- My model of MX-5 is: NC 2.0 2005
- I’m based near: Highbury & Islington
- I’m looking for technical help or recommendations on: Coolant temperature dropping
Hi there folks,
Just looking for some advice. In the last couple of weeks, I’ve noticed that when I start to drive, the coolant temperature rises to normal, and then it will begin to drop intermittently down quite low, and then will rise again back to normal. This happens on all roads, at all speeds, in all weather - it rises to normal, drops, then rises again. Drives absolutely fine too, with no issues so far.
Presumably something to do with the thermostat, but the heater works grand as well, so I’m just wondering if anyone has any ideas.
