my 1994 F150 302 5.0 liters is loosing coolant i do not know where is the leakage is coming. when parked overnight there is no drip of coolant and hoses are dried, but my reserviour is down maybe 1 inch from the coolant level my radiator and water pump was replaced just over 2 years ago and there is indication of leakage. any help is highly appreciated. thank you.

 

when it gets to normal operating temp and it's still running look at all the hoses

 

most of the time small leaks only show while vehicle is running. do as stated above...

 

 

thanks guys for your quick responses. there is no indication of leakage even the engine is running when parked i checked overtop and undercarriage and i could not found any leaks of coolant however, if i used the truck for the day,foresure the following morning my coolant reserviour is down and i have to top up with fluids. i wonder if this a sign of crack head gasket. thanks for your help again.

 

If you catch any whiff of antifreeze, or the insides of your windows are kinda greasy and like to fog up - could be a heater core leak.

 

thanks for your feedback when truck running and heater on there is no indication of heater core problem temperature yesterday -22 and today -20 any more idea thanks

cracked cooling baffles in the block, passing to the combustion chamber just getting burnt up. bad head gasket too. but if you are in hell well at least the cold =version of it do you have a block heater? if not thermal expansion could cause you problem if its a really bad one IE head gasket cracked block or heads. i feel that you are a casualty of your own surroundings the bad *** cold man!

 

Timing chain cover gasket?

Mine leaked before i changed it, and I couldn't actually see the leak until I did a pressure test, pin size hole in the gasket.

 

thanks for your response i guess i have to see a mechanic and have check the cooling system. merry christmas and happy new year to all members.
