Why would 2002 ford ranger 3.0L temp guage stay on extreme cold after water pump replacement?


i would think there is an air lock in the coolant system , have you run the engine whilst at stand still and opened the heater control to the hot position and leave to run for 10 mins or so , let cooldown then check coolant level

Having trouble bleeding cooling system on 2006 Range Rover. No heat and fan is blowing


The easy way need to be done:
-Make sure the is not presure in the cooling system before do thisor release carefully.
-Disconnect the upper hose from the radiator and fill water (coolant)
through the hose to the engine. If water can't get in beacuse the thermostat is closed. Simply remove it and fill untill full.

While driving my 2004 Range Rover HSE the vehicle goes into engine failsafe mode. I check under the hood and find a melted electronic thermostat wire. I have replaced both the wire and thermostat, but the...


It depends on what you mean by electronic thermostat wire. I assume you have the L322 Range Rover with the BMW M62 4.4 litre V8 petrol engine. It has a heater in the coolant thermostat which causes the thermostat to open further when the engine gets too hot.. The wiring to this often fails due to coolant leakage into the cable. Disconnecting it will make no difference to the running of the engine. (On mine, it has been disconnected due to corrosion).

Hi I have a late 1998 Holden Isuzu Rodeo D Cab 2.8L turbo diesel 4WD with 274000Km very well maintained it has a suspected overheating problem when under load. The radiator and hoses are new under a year...


the temperature gauge range of movement is still considdered an acceptable range and depending what weather conditions and other loading on vehicle eg going up hill also while towing. But some things ive come accross like possibly the water pump, at higher speeds the impeller could be loose on shaft and with pressure it may not be turning at proper speed, I would replace the thermostat for saftey measures also, while you looked at the water pump. Check out the heater hoses and pipes that run behind the engine to the other side for leaks also. check connections of temp sender unit wire on thermostat housing(there are 2 sensors on it) its the smaller of the 2.the other one is for cold starts

Have you test to see what the actual temp. is > Hook - up a scan tool ,what's the PCM - engine computer seeing for engine temp. ? 223 degress the PCM should turn on the cooling fan . You could buy a Non-Contact Infrared Thermometer With Laser Targeting at harbor freight ! Radiator very hot ????? What is the right temp .
Non Contact Infrared Thermometer With Laser Targeting

Could be a bad temp gauge . Is the coolant surging inside the cooling system ? Does it have a radiator cap ? Have you replaced it ?

2002 Jetta 1.8T blew 40A cooling fan fuse - overheated, destroyed 4 way cooling hose connector - replaced all- now it still runs very hot, inside temp reads 190 (but temp is much higher), cooling fans run...


Then replace the thermostat, because if on lower hose not hot and on upper hose scalding hot = antifreeze flow blocked by the thermostat wich remains closed!!!

Why does my cadillac 1998 deville keep overheating?


Overheating can be numerous things: Fans not working, water pump, thermostat, overflow cap, and the list keeps going. When the engine is running and heats ups, feel the heat of the top hose, if the hose isn't hot, the thermostat is most likely stuck open and needs replaced. If it is hot we know you have circulation. The cap on the expansion tank may be defective, if it can't hold the pressure of the water, it will release at the overflow cap if the cap is bad. Also check the coolant level.

Im not getting any heat and my truck is overheating


It is overheating because not enough coolant circulating through engine water jacket. There are 3 things to cause this problem:
1- Bad Thermostat is not opening at pre-determine temperature. 2- Bad water pump not turning as the belt driving. 3- Bad radiator is clogging up causing coolant stagnant even good thermostat and good water pump
Since you don't have heater, there maybe a serious problem of no coolant in the loop due to a blown head gasket. What happens is that due to the blown head gasket, coolant gets through the oil path from water jacket, so the coolant level is low not at the coolant hose level for heater core to receive the coolant. There is no coolant flowing through the heater core or heater matrix, hence there is no heater.
Check oil level, if it is high then water already gotten in the engine causing coolant is at low level from radiator. If you don't have this problem then you can be happy about that. Now go back to check on the 3 things that I mentioned earlier. Good luck.

Have you pressure tested the system? Read your manual, most likely cause is air trapped in the system.
