I read a number of articles about smoking exhausts, but would still like your opinion. I’ve just bought a Reno Clio (2000 reg) from an old lady, drove it away, but when I got on the motorway (around 70) the exhaust began to smoke-was a grayish colour-it stopped after about 20 miles.
My dad thinks it prob just needed a good run-do you think he is correct?
Thanks so much,
Hey there Heather,
Your dad could be right, but if the smoke comes back I would check the coolant level inside the radiator, and if it is low I would get your mechanic to do a cooling system pressure test to see if there is an internal coolant leak inside the engine. This is a simple and cheap test that can be done while you wait.
Make sure to tell the mechanic about the grayish smoke…which could be a sign of a head gasket or some other type of internal coolant leak inside the engine.
If by chance they do suspect a head gasket type of leak, try using this cheap over the counter additive before you spend any big bucks on the repair.
