Ok, so I'm having an interesting debate with my friend and mentor, an older gentleman who for the last 40 years has made his living restoring and maintaining vintage cars. When I repaired my water pump recently, he suggested I leave out the thermostat entirely when re-installing the upper radiator hose. I questioned that...because I figure the original engineers put it there for a variety of reasons besides just letting the car warm up properly on cold mornings...but I went ahead and tried it. I refilled the radiator with my usual summer mixture of 1 gallon anti freeze, 1 pint of redline water wetter and topped off by 2 gallons or so of distilled water. I've driven it on the local highways on some pretty hot days, and so far I haven't noticed any major differences in temperature. I hear from some folks who advocate running without a thermostat, claiming the faster water flow will cool better.....others say that flow needs to be restricted somewhat(by the thermostat) to allow the coolant to stay in the radiator long enough to cool properly before re-entering the water jackets. I tend to side with the latter, but I'm no engineer, so I'm curious to know what others think about this..... By the way, I'm running the stock 201 flat head 6 with stock water pump and radiator.

Good morning gentlemen, The internal vs external threads here have cause me to pause and panick a bit. Not knowing the difference, I used one of the several heads on my new build. This head has " the bump " yet the block does NOT have the by pass hole I have seen and read about here. The photos show what I have, and I've included a photo of the NOS Mopar copper head gasket I used. I appears to me to NOT have the bypass hole either. Please review these pix and see if I am seeing what I'm afraid of. Question, will this gasket cover the hole in the HEAD and therefore I'm fine? OR .... should I take off this head and use the NON BUMP head ? OR ..... is there more to this ??? Thanks all for bailing me out. Clay

Has anyone seen this or tried it ? Is this recommended for positive results ? As copied from the Vintage Power Wagon site. "In some cases you may want to drill a 1/32” hole in the top plunger (the piece that opens) of the thermostat towards the outer lip. This allows for circulation before the thermostat opens, reducing deposits in your cooling system and reducing the possibility of pressure build-up. This also helps bleed air from the system, reducing the chance of air pockets which can create hot spots in the engine. Don’t forget to replace the thermostat housing gasket. "

I had these photos of a '41 Plymouth and noticed the item that appears to be involved in the cooling system. Has anyone here seen this before and can identify it? John R

Hey everyone, Got a little dilemma, here. Recently got my hand on an Edmunds Aluminum head for my '55 Flathead. All the bolt holes line up. The only difference is, as opposed to the stock cast head, the 'hump' in the front for the water pump is absent. As you can see in the first photograph, this is how much lip is left once the head is aligned. The little bypass port is exposed. The second picture is just to show the area clearer. Does one plug the bypass? If so, any recommendations on what type of sealant to use to plug this? I've been going crazy trying to figure this out. Any tips would be helpful and appreciated. Thanks!
