Hello everyone, I have a Kia Frontier 2.7 Motor J2, I bought it with 280,000 km, I think that everything Party when the viscoso fan of the fan fails on a 3000 km trip, I realize that the hoses were tougher and the engine was heated, the temperature indicator never fell, we changed packaging many times, even so much squeeze the bolts, one is broken. The butt was rectified, hydraulic test was made. .
The shirts are dry, they are not cooled by water, if fissure, the compression passes to the carter.
As they said in the forum The thermostat is double effect, when the water opens up the radiator and closes down to force circulation through the cylinder head and block, if you take it you have to place a plug in the hole that closes in the lower part that is an aluminum feet where the thermostat runs and there can be removed the thermostat, when closing down and have open, the water circulate .
I have a doubt with the packaging, the diameter where it together or sits with the shirt is less than the diameter of the packaging in 1.5 mm per side, I have seen other packaging of other engines and the diameter of the packaging coinsidate perfectly with the diameter of the cylinder there are no differences.
The cylinder head was oxidized and chopped the surface on piston 1 and piston 4, will be fined in 1 and 4?
I am not a mechanic I am an electrician.
