Thermostat

[JMO]

Hi everyone.

I bought a new thermostat today and i have just relised that it does not have the valve that closes over the bypass system when the thermostat opens. I have been reading through a few threads and some say that ford now use this type of thermostat as the AU had issues with the other type. Should i use this type of thermostat or should i get one with the valve that closes the bypass?

This is the thermostat that i have bought:

Also if i keep this thermostat should i cut off the little ball attached to it as some have suggested?

Thanks for any help.

It is the recommended thermostat however I would rather go the DT14A which is an 82 deg. (instead of 91 deg DT14B) or if you really want to have it open earlier and stay open longer then DT14C is 71 deg. All of these are still hot enough to protect your engine however you will get some argument and debate but I have been using DT14C (71 deg) in Ford V8's for years and some motors had hundreds of thousands on the clock.
All of these are identical except for their opening temperature.

i have used that type on nearly every car i have had, never had a problem, i am also using the 71c like Howesy, i`m thinking of putting a hot one back in for winter though, i like the heater hot as it will go in cold weather, if they don`t have the little ball( for me to cut off) i usually drill a couple of 1/8 holes in them near the edge, i don`t think it really matters that much though, i have always done it with the thought it could be a help in bleeding air through the system after a system flush, someone also mentioned a while ago about reducing thermal shock when the thermostat initially opens from cold engine which also sound`s feasible.
