is the 1st and 2nd gen thermostats the same ir are they different?

thanks-

 

Why do you ask? Is your car modified? Are you having a hard time finding a 2G stat? 420a or 4g63?

 

i would think they would be different, especially for a 4g63 and a 420a... but maybe not for a turbo 1g and a 2g... but a non-turbo 1g 4g63 and a turbo 2g could be different... i have no idea haha... i would just order the one for your car, that would work the best

 

unless the car had a swap done, then you order one for the engine.
