i know, im not trying to be a smart ass. im just telling you that if you were to tell the dealer you needed one for a b16a or for what ever type of car the b16a came out of, they would give you the right one. plain and simple. unless the parts guy is a dumbass like lorraine.

lorraine, come shut me up punk

so, its not the thermo. your coolant system is a pretty basic system that is easy to work on. there are only a few things that could be wrong. first i would highly suggest that you get a helms manual or service manual. this will save you time and money and well worth the price. like cronic said try taking out the thermo. are there any leaks? if your water pump isnt working the seal may be burned up. this could happen from running the car without any coolant or not enough coolant. make sure you have a good ground. if none of this works, pm me, and i will come work on your car for free!!!!
