Burning rubber spell after towing CR-V several hundred miles

Rubber dust on the engine and exhaust.

Mikestock,
It's not the radiator that picked up material, it's the EXHAUST SYSTEM. You see, when you drive a vehicle, the exhaust system, which is sometimes, the lowest point to the road on many vehicles, gets very hot due to the engine exhaust traveling through it. Then there's the Catalytic converter which, runs even hotter. So, as you drive, anything that comes in contact with that exhaust system, gets immediately burned off and, you don't notice any smells.

But, as you TOW a vehicle, the exhaust on the toad, is COLD. Therefore, ANYTHING that can possibly stick to that system, i.e. water/mud, dust, debris, tar oil, (from repairs by road crews), tire dust(highly unlikely), anything that gets turbulated around the undercarriage, can potentially stick or cling to that exhaust system.

Now, you disconnect that toad, and, go drive it someplace and guess what, it heats up to the high temp it runs at and, vuuuuuaaaalllla, you have buring collected material. It will burn off after a short time. Just about everyone that tows a toad, will experience this, some more, some less, depending on the conditions driven/towed in and, just how well the exhaust system is concealed in the undercarriage of the car/toad/truck etc.

Best answer. You get the gold star.

If it weren't so dang far across Texas the trip would have been a lot shorter. If have since levied a complaint to the Texas state government, but haven't yet heard any resolution.

Thanks for the answers.

the 6:00 news sez Texas is moving into the Gulf so everybody can squeeze up. They're tired of being whined at for taking 2 days to get across in any direction

We flat towed our CR-V behind our Phaeton for 1800 miles over 4 days and made stops at least every 4 hours and ran the CR-V several minutes, shifting through the gears, as recommended.

We made a few short trips when stopped at overnight stays and noticed no problems. However, when we reached out destination, we noticed a distinctive hot rubber smell when driving the CR-V for longer errands. The smell eventually dissipated after a day or so but came back after the 1800 mile return trip. Once again the smell stayed around for a day or so.

It has been three months since the trip and we have experienced no problems or smells.

My only thought is that the radiator picked up rubber material from the roadways and burned off once the CR-V was driven any significant distance. Just wondering if anyone else has experienced any similar phenomenon after long tows.

1800/2 x 7 = 63 days to go 1800 for me, but I am not in a hurry to get any place.

"1800 miles over 4 days" Yuck.

The same happened with two different dingys (both Ford Edge)we had. Like you said the smell went away fairly quickly and we never noticed any problems with the cars.

What he said... our yearly trip to Quartzsite takes a few mins to burn it all off

Your last paragraph answered your question.:)
