UPDATE BUMP read below in reply
What have i done wrong.
In test car i had engine running sweet now ive taken it all out and put into the newer car ive got a couple of problems.
So before i go poking about tomorrow i wondered if anyone could tell me the normal checks.
1st problem . Engine Motor control error ( could it be Lambda's )
2nd problem . Fans will not cut in but do work if i remove sensor wire (is this just the sensor)
3rd problem . Coolant seems like its not moving which could be the thermostat but what i need to know is does coolant run through the sandwich plate oil cooler when the thermostat is closed.
4th problem . Temp and fuel gauges not working ( mentioned as maybe connected with other problems)
Ive just gone and bought a brand new 70ah battery to rule out battery degrade, as this is a common reason for engine motor control issue.
New water pump was fitted so must be thermostat
Dont be shy chuck info at me
