Rover 25 1.4 2004 hot engine and radiator fan problem


Yes, it is possible to install a thermostat backwards, though unlikely. If the thermostat isn't opening properly, the hot engine coolant won't be flowing over the cooling fan switch and give you high temps. I would first determine if the thermostat was opening at all, and if it is, is it opening at the proper temp. I have had many new thermostats that, while new, didn't work correctly. To check the cooling fan motor, turn on the AC(if equipped) and the fan should engage. If no AC, disconnect the cooling fan switch, and the fan should engage. Check for power and ground at the fan motor. If you have both power and ground, the fan motor is faulty

Engine cooling fan only works when ac or defrost is on


if engine at long stand still,the engine temperature will rise about 190 degrees the cooling fan suppose to automaticaly turn on when coolant temperature sensor get hot it cause its resistance decrease causing pcm to send power to coolant fan relays and cooling fans, when you turn on AC the cooling fans suppose to turn on to cool down AC CONDENSOR, IF NOT AC WONT WORK COOLING FAN COOLS DOWN REFRIGERANT SO IT CAN RECYCLE THROUGH THE SYSTEM AGAIN.your cooling is suppose to turn on when engine at a sit still if vechicle not moving as coolant temperature rises at a set point the cooling fans will turn on cool down engine.cooling fans dont turn on when you first cold stsrt vechicle unless you have AC SWITCH ON.if cooling fans dont turn on when vechicle at a long stand still or moving along slow traffic.if coolant temperature sensor been replaced and fuses and relays okay have dealership check see if pcm driver circuit working faulty pcm will cause cooling fans not to turn on.

there is a thermal fan switch on the radiator that drives the relay.

the things to check are,the fuse,the thermal fan switch,the fan relay and the fans themselves.
if they all check out ok,it is the fan control module that is blown.

Find Someone else,
Have Them Replace The Fan Selector Switch,
There Is Only 1 Fan In The System, Since You Can Select Between Defrost, Dash, Floor,
But Cannot Control Fan Speed/Shut-Off Fan.
I Would Replace The " Fan Selector Switch" Installed In Your Heater-A/C Controller Unit
Mounted In Your Dash.
Take Care God Bless

My radiator fan does not work under any conditions, all fuses ok, wondering which relay is it to check conditions, thanks


Here are the cooling system diagnostic steps...First does the cooling fan kick on (with engine hot)? If not, check the fuse, if good then check the thermoswitch in the radiator (it's about an inch and a half in diameter located on the lower part of the radiator with two wires ) by disconnecting the wires and touching them together (again, with engine hot...at least 190 degrees) if the fan comes on, you have a bad switch. If not connect a 10 gauge jumper wire from the battery to the fan itself (there are three terminals,,, one high, one low and ground). With power direct from the battery (and a ground wire, if necessary) fan should run... if not replace the fan assembly... if it does run then you have a bad cooling fan relay. It will be located above the fuses on the fuse block... Hope this helps...;-)
