SOURCE: 97 transport 3.4 engine- New radiator,

Are your cooling fans working? that will definately be a problem if not working. if they are working shut car off and feel the radiator is it the same temp all over or is it hot in only top or one smaller area. if you do not have same temp feeling on all of radiator your radiator may be plugged.

A pontiac montana ? There are three relay's that control your cooling fans ! unplug what sensor ? The engine coolant temp. sensor is an input to the PCM - engine computer . When temp. reaches 213 degrees the PCM energizes the relays , depending on low or high speed . Using a scan tool to see if the PCM will turn on the fans an checking engine coolant temp.data is the right way to diagnose this . Relay Driven Dual Cooling Fan Diagnostics

My car fan come on when the car at normal temp constantly. I just replaced a cracked radiator and thermostat. Now my car fan constantly run when the car is in park or stand still


you have created an overheating problem by replacing the radiator and the thermostat and not ensuring that there was no air lock in the cooling system
The fan is now constantly running because the coolant sensor is reading a high coolant temperature
First step is to ensure that there is not an air lock in the cooling system by bleeding the air out and if the fan still runs then check the way the thermostat was installed

Peugeot 206 temp gauge issue


Make sure the coolant level is correct. If it is, could be a bad water pump or a clogged radiator. Check the radiator to see if it looks like the inside has a lot of scale and deposits. Remove some coolant if necessary. If the radiator looks relatively clean , could be a bad pump.

Peugeot 406 coolant temp warning light


1. Check the coolant level if you have not already.

2. The most likely cause is a stuck thermostat so that when the engine is getting up to operating temp the thermostat is not opening at all - or enough - for the coolant to flow freely between the radiator and the engine to cool the heated fluid. If you check the radiator after driving and find it is cold it is a sure sign that the heated coolant that is circulating through the engine at operating temp and higher is not getting to the radiator. The first thing I would do is to change the thermostat and re-check. At the same time completely flush the coolant and replace it with new fluid of the correct spec.

The radiator fans are not going to operate when the fluid in the radiator is cold because the hot fluid cannot flow through from the engine. The fans have a temperature sensor switch.

3. If that does not solve the problem I would suspect the water pump has corroded and needs to be replaced. However from the symptoms you have described I believe a new thermo will fix the problem.

4. Don't drive the car when it is overheating. This is a certain way to blow the head gasket and potentially crack or warp the cylinder head. (In a worst case you can crack the engine block.) It will be nice and expensive to repair if you blow a head gasket or damage the cylinder head.

Peugeot 206 Cooling fan always on.. ?


Yes, it's an easy replacement. Just put a wrench or socket on it and unscrew it. Get a replacement at the dealer, or any parts store should have it or could order it for you. Usae a wrap of teflon tape (or plumber's putty) on the threads of the new unit to prevent leaks.
Location varies, but it will be on top of the engine in a coolant passage. Check around the thermostat housing.

I have a Peugeot 206 1400cc and I seem to have a problem with the cooling fan. As the car moves cooling fan comes on and temperature gauge goes to red and the stop sign appears. Then slowly the gauge goes...


firstly you need to check the coolant level and make sure there are no air bubbles in the cooling circuit
secondly the thermostat could be damaged and stays in the closed position
thirdly the cooling radiator could be clogged and it must be flushed or replaced
you have to take into accont that it could be a faulty message sent by faulty temperature sensor or bad connector of the senser
so you need to open the hood and decide, is the engine very hot or is it normal but still the fan is on

Check the operation of the cooling fans at the radiator. While idling disconnect the coolant temp sensor at the top left (drivers side) of the engine. It will be a 2 wire connector near the thermostat housing. When disconnected the coolant fans should come on immediately, if not you have an electrical issue with the relays or blown fuse. Check the fuses first in the underhood electrical panel. Next swap the cooling fan relay with an identical one next to it, if the fan works the relay is open.
