Was having serious idle looping issues with this M20.
Finally figured out it was a coolant bubble at the sensor in the thermostat housing.
This morn, the GF started it and it did that power steering howl you sometimes get at start-up, but it just keeps going. Plenty of nasty fluid in there, and some on the return line also. Have a replacement reservoir to install, but doesn't seem to be coming from the pump.
Am ordering a water pump now, but can't find a belt tensioner for that belt in the parts companies. Tried Rock and Pelican, nothing but a timing belt tensioner.
Is there a one in the loop? Loosend the alt tensioner to stop the squeal, but am still a bit mystified which component is the problem. Fan didn't wobble at all when tension released from said alt tensioner.
PS. Best local part store power steering fluid for a commuter ? El cheapo coolant?
Thanks in advance
