Worm clamps on heater hoses

Dont do it. Your GC will hate you for it. Used them on mine 6 months ago when I changed hoses. Started losing coolant last week, went out to investigate today. Didnt see anything up front so i crawled under it and found coolant on back of the pan. Oh crap, rear freeze plug. Looked up further and saw green on the wire loom above the oil filter. Yeah! Drip! Right in the left nostril. Went all way to the back of my sinus cavity. Up your nose with worm clamps. OUCH.

Heater core clamp loose. Hoses shrink, worm clamps do not.

Pay backs are a .....

yeah I'm beginning to think the quality of the heater hoses may be questionable.

I invariably replace those silly OEM spring clamps with worm drives. Been doing it for at least 20 years. Haven't had a leak due to using worm drive clamps.


Either you didn't tighten it enough, or your hose is suspect...
