engine leaking problem. need some info.

[sleek_vp]

gotta 05 vz exec and its leaking coolant from the front of the engine, iv just fitted a new water pump so its not that but the leak looks to be coming from the left side and theres no possible places it coming from just the marks start from nowhere pretty much and running down onto the sump, very weird but if anyones in the know about this could ya lend some help thanks

[Zuicider]

the spots it is coming from nowhere, is it where the casting meets the block?

[sleek_vp]

i think it could possibly be coming from the thermostat housing gasket so replace that n see how things go

[andyman]

thermostat housing is at the back of the motor....


did you use a genuine pump or aftermarket? still possible it could be defective,

but check around the where the water outlet from the motor etc is, could be out from around there
