I've spent months scouring the internet for info on what the hell is going on with my car and this helped me 3 local mechanics said all the coolant doesn't flow through the heater core to the other side of the engine that there was a second route and this proves My suspicion thanks
I purchased & now have a 07 Pontiac G5 with the ecotec 2.2 vin-F & it stays cool SO FAR ANYWAYS BUT, IT WAS WINTER TIME but, I have never seen the fan run period! It cycles between 183 & 195 mostly but, when sitting still on a warm day idling, I've seen 210-211° & yet, the fan has NEVER TURNED ON PERIOD! IN the underhood fuse box, there is 3 spots for the cooling fan! (There is cool fan 1 & 2 which each use a 5510-0329 relay, and there is the 3rd spot marked, "cool fan") which is a 5 pin relay but, there is no relay in the socket!!!!) Can anyone please tell me what relay i need? From the bottom of the fuse box, in the middle row, its the second relay up FROM THE BOTTOM, MIDDLE ROW. cool fan 1 & 2 both use a four pin relay marked 5510-0329, but what goes in the 5 pin socket marked-"cool fan"????????????
Thanks, 08 Cobalt with overheating issues. Dropped coolant and new thermostat still gets about 220 degrees. Will flush out heater core and change coolant sensor. 👍
I have a 07 Pontiac G5 & I have never seen my fan run period! I know how to make the fan run but, when I open my u underhood fuse box, the very bottom of the fuse box, the middle relay, go up to the second spot up but stay in The middle row. I have a empty spot that is marked "cool fan" but its empty & i don't know what relay to install? Please go to the bottom row of relays of the underhood fuse box & look at the middle relay, then go up to the next spot & i have a empty socket.....can u please tell me what relay is in your fuse box? What are the numbers on the relay?
I have a 07 Pontiac G5 & I have Never seen the fans operate on their own period. So, I've done some testing! In my underhood fuse box, there is cool fan 1 & 2, plus a spot marked "cool fan" but, THERE IS NO RELAY IN THAT SPOT! IF U GO TO THE VERY BOTTOM OF THE FUSE BOX, LOOM AT THE MIDDLE RELAY, THEN GO UP 1 SPOT. THAT SPOT IS EMPTY IN MY FUSE BOX, ITS A 5 PIN ,& WHEN I GROUND THE TOP LEFT PIN IN THAT "COOL FAN" SOCKET, THE FAN COMES ON SO, I RAN A WIRE FROM THAT PIN, INTO THE CAR & TO A TOGGLE SWITCH THEN I CONTINUE THE CIRCUIT TO A GROUND......CAUSING THE FAN TO RUN. CAN ANYONE PLEASE TELL ME WHAT RELAY GOES IN THE COOL FAN SOCKET???
