rough idle, radiator fans

[Joeyxx07]

ok heres the thing, i have two big problems.

1. My car idles rough! it shakes hard especially after i get on the throttle. i have a video of it i will post if need be. Also to deal with that, when i shift to reverse my whole entire engine moves up and drops hard. Dont know why, ill take a video of it tonight,


2. My radiator fan won't turn on. My fans kick on when i turn on the a/c on but not on idle it doesnt cool down the engine, and i overheat after running it over 45 for a period of over a half hour.

I would check your motor mounts for the engine shaking and coming up and down. For the fans I would check all fuses and relays. If that does not help then get back to us.

You need to be more descriptive. Have you done a compression test? leak test? have you done your proper maintanence? Have you checked your fuses? Have you checked your ECU?

Get back to us with a list of things you've done and we can help you further. My guess would be that you have a huge boostleak or your timing is off (for your rough idle) and your relay for the fan is busted. Start small in your diagnosing and go for the big stuff later.

ok well i need to find someone to perform these test, because im not too smart in this field haha the idling hard isnt the biggest problem, how do i check the relay on the radiator fans??

Look at the part number on the relay. Then in the same fuse/relay box, find a relay that has the same part number. Temporarily swap.

Look into your tranny and motor mounts real good

I was extremely new to mechanics before my Laser. And I had similar problems with shaking and such. It turns out I needed to replace all of the motor mounts, including the one in my transmission. I recommend looking at those as kspharris suggested. As for the fans, again, make sure the proper fuses and relays are all good, and make sure all the wiring is hooked up correctly. I have issues with overheating as well that I need to investigate. Make sure that the proper heat shields are in place (exhaust manifold, and lower turbo manifold). Those produce a TONNE of heat, and reduce the effectiveness of your fans also.
