slight smell of antifreeze at start up
Just wondering if there is anything to worry about .. When starting the AA cold (and only cold ) I have a slight smell of antfreeze .. no leaks .. no smoke ... etc. This engine runs great , has good compression etc. As far as I know she has never been apart ... Should I possible check the torque on the head bolts ? The truck is only used for car shows and the odd parade now and then .. She is never road driven ... Should I even worry about it .. the antifreeze smell goes away in a minut or so ( I suspect the coolant residue is in the exhaust .. that just my guess ... Need some advice .... Thanks Harry / Pepsi Mechanic

I would keep an eye on it but wouldn't worry about it!

Re: slight smell of antifreeze at start up
Yes, check the head nuts. I've been running an old used engine in my 28 while I rebuild the original engine. Last summer I pulled the plugs just to check the compression for the heck of it, then last fall I put my tool kit plug wrench to the head nuts and found a third of them a bit loose. I never smelled antifreeze and never had a leak, but I pulled then tight anyway.

55 foot pounds. One at a time, back the nut off 1/8 turn, then with one smooth motion tighten to 55 ft. lbs.
I didn't have a torque wrench handy for mine, so I just tightened until I thought it was 55 foot pounds. |

Re: slight smell of antifreeze at start up
my solution would be to purge the anti-freeze from the system in good weather..........
