Engine cooling system runs under pressure and at very high temperatures. If filler cap is taken off before pressure is set free, scalding coolant will blow out. Due to high temperature of coolant bad burns can occur if contact is made with skin. Do not touch any part of the exhaust system while engine is running. You can get badly burned. If the engine has just been shut off, wait until the exhaust system has time to cool down before doing any work. Because of their higher power, 24 volt systems are more dangerous than 6 or 12 volt systems. Do not let a hot wire touch metal parts of the truck at any time. Flash testing by striking a hot wire against a ground will cause an arc that can destroy the lead connector and possibly the lead itself.
