Fog on windshield?? - Diesel Forum

Sheff · 03-12-2008, 10:48 AM

Returned home from fishing last week, towing a 20' bass boat 120 miles (maybe 4100lbs.) I noticed mileage sucked 10.2 usually around 13.5. I let turbo cool for 8 minutes and shut down. Twenty minutes later I moisture had developed on my windshield. HGs?? Heatercore?? No I do not have a programmer. Way to scared of problems for that, even the exhaust is stock. Truck has 36100 miles. Any ideas??

Thanks

If you had coolant leaking from the heater core, you'd smell it. My guess is you just had some condensation due to high humidity. Don't know why the mileage was so low.

were you running the AC or the defrosters on the way home? Either on turns on the AC. And if the drain tube is blocked, moisture will build up and can fog your window when you stop.

Find AC drain tube ( water drips out of it when you use the AC - or at least it is supposed to) and try and blow air up it.

I noticed today that I had exta coolant in the degas bottle. Usually its at the low mark and now its over the max mark. Is it getting ready to puke?

Found this after doing some digging. I have the same issue, fog on the windows. I don't smell anything however. A couple times recently, I have been told it smells funny when getting inside. Sweet almost... I am guessing the heater core, however I do not have any puddles anywhere...

How hard is this to do on an Excursion?

More info...

The smell is a little more noticeable now, but not a huge difference. What I have noticed is normally I keep the temp control set at 60 to 70... Slight smell sometimes. When I turn the temp up so actual warm to hot air comes out, the smell is not there. What does that mean?

Any info would be helpful, already in the middle of head gasket replacement on a Toyota. Don't have time for this... What is the saying, rains it pours...
