Hey guys, I recently had a problem with my Dieselsite coolant filter. I had a little problem that caused me to loose a lot of coolant and make a huge mess of things. The heater hose T-fitting is obviously spun on a lathe as well as the barb but the problem is that the 3/8 barb fitting is simply press-fit into the main tube. Which when under pressure caused the barbed portion to pop out and dump super-heated coolant all over everything. I fixed it by simply drilling (8.5mm) and taping (1/8NPT 3/8) hose barb in it's place and it's now it's good to go, for good. Anyway, I figured you guys would like to know of a potential source of a sudden coolant drain. Here's the pics.
