[DeTomaso] please look at this pic of a water pump and tell me if it has a bypass hole

The last 351C thermostat I bought came from NAPA.  They didn't know the difference between a W or a C but when I showed them the old one they were able to find it on the shelf.  It was a Stant unit.

(and proper 351C thermostats cost the same and are available anywhere).

Mike, where do you find them so easily?
I searched napaonline and they don't list them (I searched for a 1970 Mustang 351C)

I'm going to order one from FlowKooler unless you know of a common source for the Robertshaw unit.

The PI forum has a thread on this:

>>>Indeed.  I must say I'm appalled that a Pantera professional wouldn't understand the importance of using a 351C thermostat when you have a standard 351C water pump.

I spoke with a different vendor (who shall remain nameless) in very strong terms when I received a water pipe/hose kit on behalf of an unsuspecting European buyer.  He had included a 351W thermostat instead of 351C.  I called to find out WTF?  He said he doesn't bother selling 351C thermostats because they are 'too hard to find'.  I tried to explain that not running a 351C thermostat would cause overheating (and proper 351C thermostats cost the same and are available anywhere).

His response?  "Ah, Panteras always overheat anyway--even if you put a big radiator in the front you can never really get them to cool right".

Well, DUH!?  Of course not, if you've handicapped it with a 351W thermostat!!!!  He still didn't get it.

I have since laid in a stock of proper RobertShaw 351C thermostats, and when somebody buys a water pipe/hose kit from that guy, when it gets here, I pull out the 351W thermostat (that he still includes) and replace it with a proper 351C unit.

Tara at Hall Pantera was doing the same thing, but to her eternal credit, when I explained why that was a bad thing, she was very thankful, and promised to switch to using 351C thermostats right away--the next time a hose/pipe kit from Hall arrived, sure enough, it had the right one included.

It was still a cheap Stant unit though, and as a matter of principle I substituted a RobertShaw example after conferring with the buyer.  Call me superstitious, but after having suffered two breakdowns in my life due to thermostat failure (in non-351C applications), I have become somewhat of a fanatic about getting the best quality unit you can.
