Has anyone else had problems with Griffin products? I am currently on my second rad from them. The first one wouldn't hold fluid because they had put the bottom three sheetmetal screws that secure the fan assembly to the rad right through the bottom cross flow tube. Getting them to warrentee this was a fight that I eventually won. After 687 miles the replacment rad has now failed. The top 8 cross flow tubes have seperated from the headers on both sides. I have yet to hear back from them on the warrentee claim. I always viewed Griffen as one of the better cooling system companies out there...until now.
