The water pump in my trecel is damaged and i need to take it to a shop that's about 20 minutes away from my house will turning on the heater and adding coolant help me to get the car there without damaging the engine
If you have electric fans to cool the radiator down you can turn on the airconditioning or the defrost which will make the fans run continuously keeping the water cooler for a longer period of time
Yes. I would recommend taking a jug of water with you. Keep an eye on your temp and if it gets too hot pull over wait a while then add more water. Turning the heater on will help pull the heat away from the engine which will help keep the engine cool. I just had the same issue with my 95 Civic and the shop was about 25 minutes from my house.
