Compared to last year, the humidity felt higher than the temperature this summer.
As with the human experience, high humidity seems to have a large impact on the car than high temperature, and the problem of coolant leakage and the electrical system occurred frequently.
Regular replacement is required for coolant over the engine cooling system.The main ingredient, ethylene glycol, does not deteriorate in a little, but it consumes anti-rust agents.
The role of anti-rust agents is to react with exposed metal surfaces of the inner walls of the path to form an anti-rust film.
The formed film is peeled off by vibration of the engine, and when the new metal surface is exposed, a new film is created.Repeatedly, anti-rust agents are consumed.
Coolant, which has almost no anti-rust effect, does not freeze below freezing, but the problem is that it significantly degrades the metal and resin in the path.Deterioration of the coolant path is severe, and it is not uncommon to have resulted in damage equivalent to the total loss.This is why strict replacement management is required for years and mileage.
On the other hand, the engine oil of the liquid which flows inside the same engine.
Since the route is different from the coolant, it seems that there is no relationship between each other, but in the individual who continues to use the synthetic oil of Group IV, especially in imported vehicles, and the individual who uses the engine oil below it, the deterioration of each part in the engine room is completely different.
Resin of imported cars that are considered to be weakcompared with domestic cars.Deterioration tends to progress rapidly as the temperature is high, so we believe that reducing friction with high-quality engine oil, reducing the heat load on the coolant path, and relieving the hot air in the engine room will lead to a longer life than anything else.
Now, the owner of 141 pandas who are familiar with the importance of coolant has contacted us when they discovered a weak coolant leak.
When I replaced the radiator four years ago, I told him that the next thing to leak was from the heater core.
Genuine parts of the supply end Fiat Panda 141AKA radiator replacement
The 141 panda is a structure in which the air conditioning enclosure is placed in the engine room.Most cars in recent years are located in the back of the indoor dashboard, so it can be said that it is structurally simple.
Heater valves are installed on the left side of the battery and on the right side of the air conditioning enclosure.
In the inspection mirror, coolant leakage was confirmed from the joint of the resin valve.
I am also concerned about deterioration of the heater core body, so I order eduterrass for heater valves and heater cores, but unfortunately the supply is finished.
The customer successfully found an external product from the same supplier as the letter MAGNETI MARELLI on the top of the air conditioning enclosure.
Remove the air conditioning enclosure.
It is integrated with the control lever in the room, and the engine room can be seen from the room.
As you can see from these arrangements, the underneath the air conditioning enclosure in the engine room is the feet of the driver's and passenger seats.
The flat windshield is located close to the occupant, and the view is good, and it is an excellent design that does not feel strangely cramped though it is very compact both inside and outside the car.
The heater core, which was removed by dividing the housing into two parts, was able to confirm coolant leakage from two locations, the joint of the heater valve and the connection between the heater core.
Finally, the coolant is injected, but does not touch the resin air vent plug on the heater hose (return).Disconnect the return hose and open the heater valve to inject coolant.
Fiat Alfa Romeo has a similar resin plug, but it may deteriorate and break, and there is no supply of single plugs.
We are currently looking for alternative parts.
