BBC with mechanical water pump will hold a lot of pressure for a week or more. When I remove the cap 6 or 7 days after the last drive to check fluid level, the water blows out with pressure. It doesn't seem to loose any fluid while driving but does seem to run hotter than I would like. Have been told it might be a HG issue but I cant see how if it isn't blowing anything out. If it was leaking and building up pressure, why doesn't it leak back into the cylinder but instead stay in the cooling system and stay pressurized for sooo long. Any thoughts or theories appreciated.
if its a leak in a head gasket, or a crack in the head or block, its reasonably east to test for,
you might have a semi restrictive or not fully functional thermostat,
or a lower radiator hose that's partially collapsing under suction,
you'll need a lower hose with internal spring support.
ID also suggest drilling two 1/8" holes in the t-stat flange to insure air can't be trapped under the t-stat,
and that you install a NEW 180F-195" t-stat as they are fairly cheap and it will eliminate a potential issue source.
adding an OIL COOLER, with a powered fan, a clutch fan, with more blades and a larger diam. matching shroud,
and a larger capacity baffled oil pan, and a larger capacity radiator, ALL FOUR options tend to reduce engine operating temps
yeah I know many of you would rather dig your eye out with a red hot fork rather than read links
and sub-links but you will be amazed at what you might learn doing so anyway... and trust me, in most cases..
you won't die from the hour you spend doing so!
What difference does it make if you install a 180 degree thermostat or a 190 degree if the car always reaches normal operating temperature of 200 in a short time running? Riddle me that one Batman!
a large well designed aluminum radiator ,matched to a high volume water pump is a huge asset to the cars durability in most cases, match those with a separate transmission fluid cooler with its own temperature controlled fan,and a large capacity baffled oil pan with a windage screen,, and an oil...
I got asked if USING anodes, in an engine is a good idea? electrolysis can rapidly cause damage, use of a 50% anti-freeze/50% water coolant mix and at least two good separate engine grounds to the cars frame helps but get out a multi meter and test for voltage in coolant, (more info in links)...
have you ever read stuff posted on line and just shake your head at the lack of facts or in some cases outright MS-INFORMATION being posted? Honestly I'm amazed at the common myths and out right ms-information that's constantly repeated over and over as if it were facts, and a bit mystified that...
Hi there, So I'm looking for guidance regarding how to choose an engine oil cooler. I don't want to get one too small or I guess too large. I looked through the threads in part of the forum but did not find anything that popped out at me that I could use to help me. Any guidance or references...
the caps designed to be a one way directional valve that will allow it to SUCK coolant from the overflow storage tank, once theres negative pressure in the radiator after it cools and the coolant and air trapped inside the radiator contracts, but its usually designed to not allow positive...
I thought this article explained very well why slowing down the flow of coolant by using a restriction is wrong. Also goes a long ways to uncovering many of the myths that surround a cooling system. Mr Crook gives us some hard numbers that can be used when picking a radiator, such as the number...
cooling fans come in a large variety of types, but the idea is too increase the flow of heat absorbing air flow over the fins of the radiator while maintaining high cooling system efficiency and engine durability and low loads on the engine. an engine driven fan is fine, the main factor in...

read this, yes theres a good deal of info in the links worth the time and effort, and yes its well worth your time to read thru keep in mind, that if your engine is mechanically functioning correctly, IE there are no problems like leaking head gaskets or the wrong head gasket or a cracked head...
lower radiator hoses can collapse due to pump suction if you don,t have the type with the structural spring to keep it at full diameter,
early mustangs used a separate spring that was inserted, obviously,
you can buy and insert these springs in almost any car lower hose to prevent hose blockage,
and yes the pump you have may be defective/busted internally
