hello,im in need of quick help,im planning on buying a gxl s5,now the factory alarm will not shut off thats prob one,but most important the seller started the car for about 3 minutes top,i was in ny so it was very cold,now when he shut the car off,i checked the oil looked decent,then pulled of the rad cap and it had pressure and would flow coolant out ,with the car off?,and it was not even run to tempature,because it was on for less then 3 min,i planning on picking up today,please give me some advice,so i dont wind up with a project,thanks in advance.

 

why did he only let it start for 3 minutes? only takes 4-5 minutes to warm up. you can do a search for alarm problem, as i know i have seen some posts about it within last couple weeks. Check these two links.

the coolant racing out after a short run time is a very strong indicator that the motors water seals are blown. to double check this, have the car run with the cap off.. if it spews coolant out or keeps forming air bubbles, then the motor is shot.

reason being is that the pressure created from the engine combustion cycle is leaking into the coolant jackets and pressurizing the coolant system.

 

there will be pressure in the cooling system even in as low as 3 minutes of run time, that is no indication of a blown water seal.

you do need to watch the system when it is cold for air being pushed into the cooling system, not trying to pop the cap off after the car has been run for a short period. also look for signs of block seal in the filler neck and for coolant type of smell from the exhaust while warming up.

 

thanks for the help guys,the reason for the short start is the alarm it was 10 at night so i didnt want to bother neighbors,the rad was cold it was 20 somthing degrees out,should i start it with the cap off,thanks.

 

Yes.

 

supra and rx-7 factory alarms are disarmed by using the key to unlock the driver side door. try that, if not sorry for the bad luck

 

I removed the cpu drivers side kickpanel,and the alarm is not working,but now i have all the dash lights parking lights,will not turn off,even when i plug the cpu back,can anyone chime in,thanks.

 

do you have a factory or aftermarket alarm system, cause if its aftermarket then you've somehow messed with the wirering and overloaded the alarm system

 

its te factory alarm.
