Does the smoke go away or does it smoke constantly ? Does the vehicle seem like it has no power and will not go over a certain speed ?

Smoke goes away if I get on highway an get off car putts an shut off but this is my 2nd time putting coolant in the radiator

It could be a head gasket because the anti- freeze is getting only into the exhaust system. Does not have to show a leak. If it does turn out to be the head gasket let me know may have a quick fix that might hold you over if you do not have the fund to get it fixed at this time.

Yes to much anti- freeze going into cylinder from head blown head gasket can cause not to start. If vehicle is still running and smoking

20

Oh okay what to do funds not right

If vehicle was still running and smoking not much anti- freeze getting into cylinder or cylinders the product that I would suggest only might work if vehicle is running

Ok I am going to make a suggestion to you it may work or it may not but I am just trying to help you out. First remove spark plugs from vehicle clean good and install back in vehicle hopefully vehicle will stay running for about one hour with out missing. Then buy a bottle of bars radiator and head gasket sealer put in radiator. If no radiator cap remove top radiator hose pour into hose then put back on. Run vehicle following instructions on bottle. Hopefully it will stop smoking with in a half hour to an hour. If it does not work do not continue to add more stop leak hoping it will work because it will do more harm then good like clogging up your cooling system. Ok that's it hope it works for you if you decide to try it and no promises it will work but it's worth a try.

When I try that how long can I drive

17,320

If it stops smoking you can drive it right away but no guarantee how long it will work hopefully long enough for you to get your funds together.

Okay I should buy the expensive one? An thank you

It's called again Bars Radiator and Head Gasket Sealer. ( Google Amazon ) type in Bars Leak Sealer and check out reviews of the product and then make your decision if you are going to try it or not. Now if it works its not a permanent fix.
