You could have a bad thermal switch or you have bad fan or a bad fuse or relay for the cooling fans.

Why would my 96' cadillac seville be overheating after i put a new radiator a new water pump a new thermostat and new fan motors in it


Someone would need to test the system and find out at what point the engine is overheating.
Is the thermostat not opening - is the coolant not flowing - or are the fans not coming on when the coolant reaches 220 degrees ?

2003 honda civic ex overheating. I have replaced the waterpump, radiator and thermostat. car is still overheating. I have followed all repair manual directions. what else am I missing????? sensor bad???...


Replaced the temp sensor? "Burped" the system? Sure the thermostat is in the right way? You can even try running without the thermostat to see if that helps.

Overheating fan will not run ! I change cooling sensor, fan relay,new radiator, thermostat, fan motor, check all fuses, tank low coolint sensor, put fresh coolant in also. (1998 achieva SL 3100 V6 SFI )...


there isa short in the wiring somewhere,which a shop can check for you,or check your thermostat. after 20 years i still have to make sure tat i dont install it upside down. which is easy to do if your in a hurry. my bet is that the wiring going to the coolant sensor has a bare spot and grounding somewhere.

My pulsar in overheating put new coolant in no change fans dont seem to be working but engine was hot and gauge showing only halfway, cant find the thermostate is it in the housing the top hose is...


Make sure the fans are coming on or it will over heat. If the fans come and the gauge is reading hot check the thermostat. Follow the top radiator hose to the engine block it probably has 2 bolts holding the thermostat housing on.

2000 Plymouth Voyager Overheating


The radiator cooling fan relay has most likely failed. It is underneath the air cleaner on the frame rail just behind the radiator. NO cooling fan = overheating. This is the first thing i would look at. Best way to tell is when the van gets hot see if the cooling fan is on. You will hear it running if it is coming on. It will set a code for the cooling fan relay also.
