Hey guys pretty new to vettes and had some questions. I was wondering if the cooling fan is suppose to run all the time. If not what would cause this? I also broke the spring under the clutch pedal and the lower half is still there. Should i take the rest off or just leave it till i can get a c5 Z replacement? One more, would the car need a tune after an borla cat back was installed and a aftermarket air intake. Im not sure of the brand for the intake the to mods were on when i bought it. It seems to idle alitte weird. Bounces up and down at times. Sorry for all the stuff just want to get it running perfect.

 

GTO & G.N.?

Wrong Forum.

 

oh damn. Sorry about that i just traded the GTO in about 3 months ago for a 05 vette z51

Cooling fan; should run only when coolant temps rise EXCEPT when the A/C is on OR when the DEFROST Cycle is set. If the car was improperly tuned the fans could run all the time, better have a tuner look at it.

Clutch pedal spring; Others have broken and not replaced, some have removed for the different effort required. If it was mine I would replace it.

Axleback alone shouldn't need a tune, TRUE CAI (not just a filter and filterbox change) and axleback might need a tune, CAI, headers and axleback need a tune. That said, a tune can help even a stock car.

 

thanks for the reply. I dont know why but my fan is running all the time has anyone else had this problem?

 

Here is the answer for the clutch pedal return spring.

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

Condition/Concern:
It appears that some Corvette owners are removing or disconnecting the clutch over center spring on their vehicles.

This is not a recommended practice and customers should be advised of the implications of such an action.

Recommendation/Instructions:
The clutch master cylinder has a compensation port that is positioned within 1 MM of the top of the stroke. The compensation port allows internal pressure in the clutch hydraulic system to be exhausted into the master cylinder and also provides for system refill as the clutch disc wears.

One purpose of the over center spring is to return the clutch pedal to the very top of the stroke to expose the compensation port. The second purpose of the spring is to provide for the designed clutch pedal feel.

Removing or disconnecting the spring may allow the clutch pedal to hang in an at rest position with the piston short of the compensation port. If the internal pressure is not exhausted the CSC may get stroked too far and a clutch hydraulic system failure may result. The C5 clutch hydraulic systems were built by AP. The C6 systems were manufactured by FTE. Also, the pedal must be in the full up position, with the compensation port exposed, to bleed properly.

Anytime a dealer gets a hydraulic system complaint, the tech should inspect to insure that the spring is in place and properly connected. Related customer complaints might include poor shift performance, improper clutch release or transmission synchronizer damage.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

I did a complete cat back exhaust change to a Magnaflow system, and was getting a slight odor which I was told means it may need some tuning to bring it back to perfect, so like the other members said, a tune could do nothing but help, and definately will not hurt anything.

 

blackbox; Are you sure the cooling fan is running "all the time"?

Try starting the car from setting overnight, set the climate control to OFF(where it just shows outside temperature) and open the hood to see if the fan is moving. If the fan is running with a cold motor and Climate Control turned off you have a problem. Maybe a previous owner added a fan control switch? Any extra switches on the dash, under the lid in the console or in the glovebox? If the cooling fan is running with a cold motor and the Climate Control Off then somebody may have done a tune with the wrong fan temp settings.

 

 

thanks ill check out the fan like you said. I dont see any odd switches all looks normal. Ill let you know

 

should i put a c5 z spring in it or a stock spring?

 

the fan still runs with the ac off and started. It kicks on as soon as i start up the car no matter what i do.
