Ok, can anyone with a mustang thats has a cold engine check this for me. On the coolant overflow tank where you screw on the cap... can you check if theres a little square hole on the black plastic part. Heres a picture to explain this better: Right where the arrow is, but on the mustang overflow tank. Is a hole right there nearest to the engine side. edit:
i will go check my overflow in a sec for ya even though it is freezing cold outside because i am a nice guy lol
There isnt one on my 95 but i dunno if there would be one on the 96-98 maybe someone else will pop in. i dont think that there would a hole there
Alright, thanks buddy for checking O0 Just need a 96-98er to check. Damn, this sucks. Im 1 hour late for work on superbowl day :'( the boss is going to think im trying to pull one over so i can stay home from work to watch the game.
Yes. I just went out and looked there is a square hole that looks like its where the coolant goes out when you have too much pressure.
Not sure never had this problem. If it were me I would pull the thermostat and see if that makes it better.
maybe time for a waterpump. is the coolant boiling and or building pressure in the overflow. i just know my buddy had an old 93 ford f150 that, the coolant in the overflow would start boiling and bubbling. i took it apart for him and his waterpump didnt have any fins on it what so ever. there were little pieces of them in the block.......... changed it out for a new one and he was good to go..
Only time it was bubbling was when i drove it home the night everything went wrong. IT was popping and bubbling like a bitch ,but that was when i put 3 big bottles of water in it. Right now it doesn't boil because i turn the car off before it gets to hot and theres no white smoke coming from the exhaust pipes. Tomorrow im going to get a new radiator cap and a new thermostat. Thanks guys and rofl i took your pic.. srry :behind:
^ most of the time ,yes. and it would be steam that wil evaporate quick. smoke would linger. but thats not always the case. ive seen it happen
