Pay attention on five serious malfunctions of fire truck engine in summer

Unbearably hot in the summer, before going out, you will do a good job protection measures. But even so, in the hot outdoors, person will often feel chest tightness, shortness of breath. It is probably time to get "heat". People will get heat, but you know that fire truck will get "heat",too? Fire truck in the sun occasionally shows you a little temper, delaying fire rescue responsibility. That really is not a laughing matter, just below a fire engineer look at several incidents summer most prone to fire. 
1. puncture 
Outdoor temperature and the surface temperature reach a certain height, when the tire temperature will be very high. Tires at high- speed driving, if excessive used of badly worn, will greatly increase the chance of a puncture. While in a moving way, especially at highway speeds, the car tire an extremely dangerous thing. In general: the higher the surface temperature, the faster the speed, the more prone to puncture, the more dangerous. 
Precaution: 
   1. Regularly check the tires and preparing spare tires is very important. 
   2. According to outdoor temperature, properly adjust tire pressure. Under normal circumstances, the temperature is increased by 10 ℃, the tire pressure will rise 7-14kpa. 
   3. If tire aging, wear, tie tack and other issues, the importance of timely treatment. 

2. Engine temperature is too high 
High temperature is also an enemy of engine. But generally as long as no fault in vehicle cooling system and no over-using of vehicle, there wouldn't be any problem. But we still need to keep an eye on coolant temperature gauge, engine is substantially equivalent to that burned scrapped. 
Precaution: 
   1, When engine high temperature is alarming on, immediately park your vehicle in the cool place of road. Do not overuse the vehicle. 
   2. Make sure the antifreeze in the standard range of engine cooling system does not leak, and the cooling fan can be rotated. 
   3, Never use use cold water to cool the engine, which could cause the engine block because the quenching burst. Should unscrew the radiator cap slits so steam is discharged, after the tank pressure down, then add cold water or antifreeze. 

3. Air conditioning exception 
After a winter not opening cool air, opening in summer again that it doesn't cool the air and the outlet air flow becomes very small. At this time,what should be done to solve that? 
Precaution: 
   1, first check whether the operation properly, there are no open outlet, whether to open the outer loop, and so on. 
   2, if operating properly, check the air filter is not clogged with dust or foreign matter, clean or replace. 
   3, check whether the condenser cooling efficiency, whether covered with dust or cooling fan does not turn. 
   4, if the air conditioning compressor is not operating properly, it should be repaired. 

4. Transmission box temperature is high 
Some cars equipped with automatic transmission gearbox alarm, if you continue to use the transmission temperature is too high, the transmission will be in automatic protection to shut off or reduced power output, in the long run would be very negative effect on the 
transmission. 
Precaution: 
   1, often cleaning the transmission, so as not to lead to the accumulation of grease gearbox too dirty, not forget to check the gearbox cooling system. 
   2, the engine of fire truck and look at the situation, the same can not be over- consumption of transmission, once the transmission oil temperature overheat alarm, please step aside immediately stop cooling. 
   3, temporary traffic lights or when parking, the gearbox is best to switch to the N range, D range do not hang long on the brakes. 

5. Vehicle doors leaking 
You know, there is not only the summer sun, sometimes dump heavy rain. If you neglect to clean the drainage channels of the door, the door will be leakage phenomenon. 
Precaution: 
   1, regular vehicle maintenance seal or replace it. 
   2, above the door of a small ad if liquidation is likely to cause improper drainage guide groove door jam, this time Remove the door trim panel recommended that the drainage guide groove clean.
