An engine temperature of 90 degrees Celsius is normal, as the typical operating temperature range is between 70 to 90 degrees. Overheating may occur due to insufficient coolant, malfunctioning cooling fan, or faulty water pump. Coolant leakage or low coolant level can cause engine temperature to rise - if low, first top up to the proper level. Below is additional information: 1. Insufficient Coolant: Coolant leaks or low levels will lead to higher engine temperatures. Check coolant condition and refill if necessary, then monitor for significant level drops over subsequent days. 2. Cooling Fan Malfunction: When the cooling fan fails, heat cannot be effectively transferred to the antifreeze, impairing cooling capacity and potentially causing boiling-over issues due to elevated antifreeze temperatures.

Can Venucia be serviced at Nissan 4S stores?

Venucia can be serviced at Nissan 4S stores. Dongfeng Nissan's Venucia was originally a Nissan car, so it can also undergo maintenance projects at Nissan's 4S stores. All brand 4S stores offer nationwide warranty services, meaning any 4S store can perform maintenance. If a 4S store insists that maintenance must be done at their location, it's simply to prevent their resources from being diverted elsewhere. Maintenance cycle: 4S stores will determine the vehicle maintenance cycle based on the actual local driving conditions. For some components, the maintenance cycle may differ from what is suggested in the official manual. Maintenance precautions: If the local environment is harsh or the road conditions are poor, the maintenance cycle should be appropriately shortened, especially for the air filter element and the cabin air filter element. Additionally, the quality and specifications of various fluids must not be mistaken; choose the appropriate specifications and better quality fluids. The replacement of brake pads, wiper blades, batteries, tires, etc., depends on wear and tear, so regular inspections are essential.
