Hello I have a 1993 foxbody That had a 2.3 in it i have ripped it out and have swapped in a 1970 302 i have every thing hooked up and it runs very good my question is i can fill the radiator up full run it for about 15 mins and it starts to overheat i found out the thermo was sticking shut i fixed that now there is a problem with the coolant level after running it i can go out the next morrning and almost all the coolant is gone from the rad i fill it back up and run the car to temp and all is good when i shut the car off i can watch the coolant level just fall like the drain plug is left wide open there are no leaks anywhere i have climbed on top of the motor and crawled under the car i cant find a leak anywhere im just at a loss i have tried all i can think of also when the thermo was out the car was running i could watch coolant flowing through the radiator put the cap back on the car starts to overheat after about 10 mins in 50 deg weather there is no smoke out the exhaust no leaks anywhere idk if the rad cant cool the coolant enough or what any help will help
