[quote=”college man” post=106210]If your system is leaking coolant then it won’t hold pressure
it will overheat. The leaks must be fixed. Pressure test the
cooling system. This link will help you further.http://www.ericthecarguy.com/faq/what-to-do-when-your-engine-overheats%5B/quote%5D
My old car leaked coolant through the head gasket and I never had overheating issues. Anyways op I would make sure they’re in fact bleeding the air out, it can be a pain in the butt on some cars. Is your oil milk shake colored? Is there white steam coming out of tail pipe after the car has been running for a while? Better yet smell the steam!
[quote=”EricTheCarGuy” post=106340]That sounds like a fix! Thanks for the update and for using the ETCG forum. Stop back if you need us again.[/quote]
Will do! Your videos have helped so much with working on my car 🙂

Good news guys my uncle recommended that I replace the relay, so I did and now the fan turns off and turns on when needed! Thanks guys for the help.

[quote=”Tomh” post=105820]Obviously, we know that the fans are working. It sounds like you have tried sending power to the relay, and that is indeed switching the fans on. The next steps would be to test the wire that runs from the ECM to the relay for continuity, and also the wire(s) that go to the CTS. If all those wires have continuity, then the only other components in the system are the temperature sensor, which you can test using a multimeter, and a pot of water on your stove. If the wiring all shows continuity, and the CTS passes the test, then about the only thing left is the ECM.
I’m not going to say that this is typical, but sometimes the fan control built into the ECM just fails. As long as everything else related to the ECM appears to be working properly, and the only thing that has issues is the fan control, you can get a stand alone, aftermarket fan controller (typically sold for race cars, but you can generally find them at the big auto stores like Auto Zone, and Advance Auto etc.) and set that up to turn your fans on and off. If you pick the right control, it can even be used to switch your fans on and off when you turn the A/C on. The cost of one of these controllers is typically under $50, a whole lot less expensive than replacing an ECM.[/quote]
No one of the wires is connected to a blower motor fuse, one thing I’ve noticed is after the car gets to a certain point on the gauge I hear a relay click but the fan speed doesn’t change. However when I disconnect the wire from the fuse box the relay never clicks? The relay connectors are getting power though. The car is not overheating.

[quote=”barneyb” post=105717]What’s bad about the fan running all of the time? Some people hate the noise. The fan will wear out sooner. You will take a tiny hit in gas mileage. Hmmm – still searching for a good reason not to do this.[/quote]
I didn’t do it, who ever worked on the car before did it. When I disconnected his wire the fan wouldn’t switch when the CTS is disconnected so something is wrong. I’ll fix it when I have the money to fix it, what’s odd is there are no codes stored related to that issue.

[quote=”barneyb” post=105701]The quick fix for fan control problems is to wire the fan so that it runs all of the time. I suspect that is what has happened here.[/quote]
You’re right, the fans didn’t turn on when I disconnected the coolant temperature sensor. I’ve checked the wires and they’re all good and I’m guessing the relay works because it turns on when the yellow wire is connected to power, but maybe I’m wrong? Is there anything bad about keeping the fan on 24/7? BTW the site doesn’t have the diagram I need thanks anyways!
