At the track yesterday I had an interesting spin due to a hose letting go. Upon inspection I found that the top radiator hose, which was fairly new had a groove worn in it that finally broke through. When we did a quick repair by cleaning and adding racers tape, I incurred a second failure due to the same problem. Hindsight says I should have added a zip tie to pull it away.

Any ideas on why this could happen. Badly formed hose? I can't imagine that the fan could be out of position.

 

happened to me fan shroud bolts fell out. the fix: new bolts and radiator hose

 

Check you upper radaitor mount. This could allow the radiator and fan to move closer to the engine then it should.

As for the hose. I had this happen to me before also. I used a zip tie around the coolant hard pipe to hold it closer to the radiator. The hose failled on me in the middle of a road trip last year, I limped the car to a carquest. After searching their back room I found a nice replacement hose that fit perfectly...well I did have to cut a small section off but after that it fit better then the stock hose.

If your in a bind and need to replace this hose quickly, use carquest part # RBR 21723 and cut one bend off for a perfect fit. Most should have it in stock or be able to get it on a saturday afternoon.

 

Stephen, I will need your help to get the car prepared for my next event and even repair/replace this hose. As you may remember I do Hurricane/disaster work and will be on the road quite a bit, leaving Wednesday. I need to get the car ready for Mosport, September 20.

 

Just let me know when you want me to come out to your place. Tomorrow I am booked but whenever you want me to come over to your place after Wednesday, or if you want me to take care of anything while your away, just lemme know - 722-1662.

 

Thanks, I will call.

 

Happened to me during a race weekend, lost multiple hoses. Found out that generic hoses are not the same as OEM hoses. The OEM ones have extra bends and better clearance.

Root cause was blown /destroyed engine mounts, ie engine moving, not the radiator/fan. They were the low cost aftermarket ones, solid filled not hydraulic, never again. Changed to Lindsey Supermounts, so far no issues.
