1994 4 runner 3.0L V6 doesn't seem to be any water getting to the top Rad. hose.	Sign In

Hello, i just replaced the Radiator, A/C condencer, thermostat and all fluids in my 94 4Runner 3.0L V6. the temp guage is running about half way between H & C but the engine and radiator seem overly hot... Also i don't seem to have any water pressure returning to the top radiator hose...??? Any ideas?

Also.... bought one of those recharge cans for the A/C anyone have any tips???

A/C - OK to use the small cans of refrigerant but you still need to know it's pure and not full of junk and charge by known weight not some silly gauge that comes with most of those. Read the locked thread on charging A/C and if you don't do that into a well held vacuum don't bother at all and send that out. How much oil if just a condenser will be an educated guess and if you let us know we can help with that part.

Cooling system. It probably isn't completely full OR could be a number of things. Do you get heat? No pressure may mean the pressure cap itself is a problem or a leak still exists OR if you've had the cap off while warmed up it's not going to build up pressure right away in front of you. That pressure is from expansion of the coolant not some induced pressure BTW,

You could have an airlock in your cooling system. You said the truck seems to be running hot but temp gauge is in the middle? You could check temps on the block with an infrared pyro if any doubt as to gauge accuracy. With regards to your AC, make sure that can has no sealer/leak stop crap in it or kiss the system goodbye. If leaks are present they must be fixed with the proper parts.
