Having trouble with my 300SE
A bit of history I did have a couple of small rad leaks. I noticed a kind of acrid smell (hot antifreeze) around the front of the car after driving. On investigation I found some damp patches on the rad. I used (rightly or wrongly) a proprietory rad/leak sealer that is applied to the coolant. This seemed to get rid of the dampness and for a while it seemed, the smell. I drained some coolant out of the heater supply pipe and pre-mixed this agent with this coolant and then replaced it into the header tank.
Read on..
If I drive along the road, all is ok (as far as I can tell). As soon as I have to stop, the temp gauge starts to climb. I haven't reached the red yet, but I know it would do if I didn't get the air flowing again through the rad. I managed to get the car home and as I manouvred in, the gauge was rising. I quickly turned off and opened the hood. I once again have a burning smell, but I can't see any leaks from anywhere. Also I notice I have no pressure in the coolant pipes. So I realise that I should change the rad, thermostat, temp senser (and also the water pump, which I beleive is making a slight mechanical noise). But Where is the pressure?. Have I a cylinder head problem?
Any suggestions as to a difinitive check to diagnose my problem.
Cheers... Rob.
