Coolant Problem

[mrman3232]

i seem to have a coolant leak but i have no visable sign of leaks. i have rplaced the thermostat and housing, replaced the rad cap, i also checked each cylinder for coolant but no internal leak (head gasket). its not the heater core as there is water on the driver floor but i checked with a white paper towel and it is not green and is just water building under my mat from a hole in it. it often takes a while for the bottom rad hose to heat up. the overflow always seems to be full but when i open the rad is when i notice coolant gone. i also did a pressure test and it seems to lose a bit of pressure very slowly. any ideas?

does your overflow bottle have hole in it maybe its leaking from there ?

thats what mine was

Where is the cooling system losing pressure? Coolant is being lost somewhere if pressure is dropping. Keep the system under pressure over a longer period of time in an attempt to pinpoint the leak.

Where is the fluid coming from on the driver's floor?

i will try keeping pressure on for a long period of time but the water is only directly under the mat the actual carpet under the pedals is dry
