The easy answer in no. Diesel vehicles need to reach operating temperature every drive in order to burn off carbon. If the vehicle is only being driven a short distance to the shops it is not able to properly burn off the carbon and over time will block up internally. These repairs can be quite costly. Our advise for anyone who does very short trips in their vehicle is to buy a petrol, hybrid or electric vehicle.
Radiator plastic tanks start out black. Overtime due to heat and age, that tank will slowly start to change colour. Depending on the type of plastic different suppliers use, the tank may turn brown, green, yellow or creamy. This is normal and is a sign that the radiator will require replacement in the future. Whether it will be in 1 week, 1 month or 1 year, at some point it will crack and start leaking. Our advise would be to have the radiator replaced when the tank changes colour. This will avoid an inconvenient tow & repair when you don’t expect it.
Without knowing the exact cause of the issue, our advise would always be to tow the vehicle. If the issue is substantial, driving the vehicle may cause further unnecessary damage that could have been avoided with a simple tow.
Service schedules vary so much these days.
