Hello, what's the VIN?
Is check engine light on? Do you plan to do the work yourself? Thanks.
Is check engine light on with everything plugged in?
Also, does it ever run hot while going down the highway?
It shouldn't run hot while going down the highway because road wind act's as the fan. If it overheats while going down the highway then you have other problems. Does it run hot while going down the highway? The temp gauge normally sits in the middle.
Does temp gauge go past the half way mark going 70 down highway?
Have you replaced thermostat?
The fan only comes on when needed, if gauge isn't going to the middle then fan probably just isn't needed. Is vehicle spitting up coolant? If it was overheating it would be.
Hi Im David, lets get away from all of this when you think it should be running. I dont care if you are going down the highway or not the fan will not come on until it gets a bit over mid gauge.
i dont care if it sits there and idles for 3 hours, its not going to come on til it needs to
So what exactly is your main concern? is it overheating is the temp gauge matching a digital temp reading at the thermostat housing or the temp sensor? is the computer seeing the same temp as the gauge?
are you there?
ok, replace the coolant temp sensor for starters.
when the engine is at operating temp, are both radiator hoses equally hot?
also, once the engine is at operating temp and you shut it off, when you remove the cap, is the system under pressure?
so you have checked those 2 things?
how about the hoses?
ok. then lets work on that, but in noway should the coolant be boiling out of the reservoir, fan working or not.
do you have a volt meter?
understood. but theres still an issue with it overheating.
ok, let me look at the print for a minute and we'll start checking things
did you check the highlighted fuse yet?
pull the low speed fan relay.
ok. hang on
thanks for your patience
pull the low speed relay out. make sure you have 12vdc at position 30 of the relay plug. doesnt matter if the key is on or off. then pull the high speed relay and check for 12vdc on position 87 of that relay plug. if those voltages are there, then put a jumper in the low speed relay plug from 30 to 87, key on and see if the fan runs on low speed.
no. relays dont go bad as much as people think
once you get those checks done. we can do more.
hows it going?
were you ever able to get anything figured out?
