1991 Other Nissan Models Front Wheel Drive Automatic 198000 miles

Hello,

Ive had this nissian 1991 bluebird SEsaloon for the last 5k kilometers and latley i have stoped driving it very far (have to take time of work) becuase of this problem

After driving for about ten minutes the temp gauge creeps past the halfway point and something does not smell right

Not long after a hissing sound occurs and white/ smoke steam comes out from under the hood

I have taken a picture with a arrow where the smoke/ steam is coming from.

I have been topping up the coolant as it has been burning threw it, but topped it up yesterday and went for a 10min drive and still at the same level

A couple of days ago just before this problem happend i heard scraping sound a few times sounded like something was dragging under the car but nothing was there.

There is some white flakey stuff around by where the coolent tank is (pic attached) that was not there before this happnd

I hear liquid boiling after driving as well

Is not burning threw oil

So guttered this had to happen just before xmas and any help would be greatly appreciated!!

Thanks
Robert

More than likely a bad thermostat or waterpump.

When you start the car you should feel coolant moving through the heater hoses, if not then waterpump.
If after the car warms up you should feel coolant moving through the thermostat housing hose, if not then change the thermostat.

You mignt want to start with a cooling system pressure test, propably more than one hose is loose after the overheating.

Thanks, where would I find the thermostat housing hose?

Cant seem to feel any liquid running threw the heater hoses but it may be due to vibration.

I mixed two differnt coolant brands together could this maybe be the cause?

I dont have a pressure tester do you know of any other ways to check for loose hoses?

The thermostat would be in a housing connected to head, follow the upper hose (usually the upper but some cars it is lower hose) to the thermostat housing.

Check the hoses with your hand (engine cool) especially at the connections (clamps), feeling for any liquid, Visually check the waterpump weep hole for coolant leak.

Many coolants at autoparts stores can mix with any color, all makes, all models. I would prefer to use one coolant and drain, flush and refill.
You also want a 50/50 mixture, if you get above 70/30 you can lose cooling effeciency.
