so i went to autozone to buy my thermostat but the one they gave me was to small it had the same part number for threw out the years need ur expert advice i need my heat lol i live in a cold state and its getting preetty cold in the morning

 

the 93 and 94 vtec have the larger thermostat, 2.5" diameter I think.

 

yeah thats the year i gave him a 93 h22 vtec and he handed me the smaller one. only if my dad didnt throw out my thermostat cause we were thinking it was bad and it was my water pump that failed
