is this overheating? 233 before t-stat & 240 after T-stat?
Thanks Guy's.

Edit: This is 2-4 minutes after shutting the car off, I used a Non-Contact thermometer.

where are you getting these numbers from? what t-stat do you have? idealy you want to be in the 180-200* range.

I have a stock temp. t stat, and i put the thermometer on the t stat housing than after the t stat housing and thats how i came up with those numbers

weird...did you put the thermostat in backwards...did you have problems before you swapped.

So this is after the car is shut off and just sitting? If so, of course it is going to read really hot, there is no coolant circulating in the engine and no fan to cool off the radiator.

Okay, I pulled off my radiator cap today and i got a strong smell of gas in the radiator and the same gas smell in the reservoir tank, and inside the res. tank it bulbbles alot, and with the radiator cap off, it starts to bubble and shoot water out it only does this when it starts to overheat. I dont understand i just put these heads on, how could the headgasket go bad that fast, and i get no smoke at all of any kind out of my ehxaust and no smell either, but i havent been running coolant, because ive been flushing and refilling constantly. I am thinking either a headgasket or what else could it be, how could it not be smoking out of my exhaust GRR

You took the rad cap off when it's hot? No wonder it shot **** at you. If the temperature is above the boiling temp at your elevation/atmospheric pressure.... of course it's going to boil and spray at you. The point of a pressurized coolant system is to keep the coolant in liquid form above its boiling point.

LOL i know not to do that im talking about leaving the cap off until it warms up then it started boiling over
