Why does the Iveco engine temperature rise?
2 Answers
Iveco engine temperature rises because the thermostat is broken and cannot open, preventing the coolant from circulating in the large loop. Below is relevant information about Iveco: Nanjing Iveco Automobile Co., Ltd.: Nanjing Iveco Automobile Co., Ltd., abbreviated as NAVECO, was established on March 1, 1996, as a Sino-foreign joint venture jointly invested by Nanjing Automobile Group Corporation and Italy's IVECO S.p.A. Iveco Automobile Co., Ltd. Products: The company's products are divided into two major platforms: IVECO and Yuejin. The IVECO brand has a designed production capacity of 60,000 Iveco series light vehicles and 75,000 diesel engines annually, with products mainly including four major series: passenger vehicles, trucks, travel vehicles, and off-road vehicles.
Last time when I was delivering goods with an Iveco, I also encountered a situation where the temperature gauge suddenly spiked—it was really alarming. High engine temperature could be due to insufficient coolant, or the radiator being clogged with dust leading to poor heat dissipation. Another possibility is the thermostat getting stuck in the closed position, preventing the coolant from circulating. If you notice the fan isn’t turning on, it might be a faulty temperature switch or an electrical issue. Back then, after pulling over, I first checked the coolant level and found it was nearly empty, so I quickly topped it up and cleaned the radiator grille. I recommend keeping an eye on these areas regularly—don’t wait until the dashboard warning light comes on to panic. Especially during hot weather or long-distance hauls with heavy loads, such issues are more likely to occur. Get it checked at a repair shop ASAP to avoid engine overheating and blowing the head gasket—that would be a huge loss, with repairs costing thousands. This experience taught me a lesson, and now I spend a few minutes checking these basics before every trip.
