ok guys. im looking at a friends greddy tt car couple of things wrong need some solutions.
1st. car have a aftermarket viper alarm (i duno much about alarms) at times when pushing autostart button nothing happens. but sometimes it will crank literually about 2 seconds but car will not crank over and sometimes the car will crank over just fine. but on the oem remote the locking and unlocking buttoms still work. i know you suppose to bypass factory alarm could this be the problem? please advice
2nd. car overheats really bad. once the car starts. will not idle more than 10 mins before overheats. coolant level is good. bleed the system through the bleeder. topped off the tank. no heat coming out at all. noticed the aux fan never comes on. and when car over heats then it will go backs to my 1st problem, car will only crank 1 to 2 seconds and will not crank over. please advice

thanks

 

Not sure about 1st....but it seems to me that you just answered the question to your second problem....The fan not working will over heat the car at idle.

 

you are correct but even the car sits overnight.next morning it will only crank for 2 sec and thats it, it will not crank over.

 

update: got the fan to work. connection was little loose. try bleeding it again. was able to get heat. but temp still reading right in the middle.anyone have any advice?

 

the temps read right in the middle after the car warmed up? if so thats normal as long as the needle isnt rising higher than that.

as for the viper alarm. try to find install directions for the viper alarm you have, and uninstall it from you car. Or take it to a shop and ask them to uninstall it, shouldnt cost much.

 

hahaha, it will always be on the middle when is safe, no worries

 

why uninstalling the viper alarm ? its a really good alarm, also i didnt install remote start because it is not safe other than that, you should go to the place you istall the alarm from and claim that is not working, if is not under warranty they should at least give you any advise or tell you a price to fix it, which it shouldnt be more than 150.00. try that and let us know what happend down side you will probably have to make an appoinment

 

assumed he didnt want to use the viper alarm anymore. I agree if you want to keep it take it to a shop to be re-installed properly, or check waranty info

 

update. bleed system one more time. turn on the heat, heat wont kick in unless stepping on gas (2000 rpm), once let gas go. no heat coming out. also. after start up. it takes about 5 mins to get it up to the middle. but once shut the car off. will not be able to start it for a long time. it will crank 2 sec and thats it. would the engine temp cause that? or its a alarm issue you guys think? thanks

 

are you throwing any codes. I'd test coolant temp senor with a multi meter and see if its within spec

 

no codes at all. i think the normal temp the needle suppose to be a bit lower than the middle. it still stays in the middle at this point but i let the ccar sit for about 5 hours now and try to start it up. no crank

 

if it doesn't keep cranking, then perhaps starter motor is on its way out? Or battery?

 

update. got the car to start up again. still running into overheating problem. when the car at idle its fine gauge in the middle as soon as put in gear and drive car shuts off.(gauge still in the middle) gotta let it sit for a bit and temp gauge goes down before it starts again.

 

good battery good starter. brand new solenoid

 

How do you know it's overheating? How do you know the not cranking issue is related to overheating?
