Question about Cars & Trucks
You new to invest in a coolant pressure test tool. To use it all you have to do is remove either the radiator cap or coolant tank cap and pump the coolant system up. One the cap of the radiator it will tell you how many psi you can pump the system up to. Normally around 14-16 psi. By using this tool you don't have to crank the engine to build pressure in the coolant system. Plus this tool can and will keep you from burning yourself on a hot surface. After you pump the system up. Just get a light and see where the coolant is coming from. I hope this helps.

try to run the water pump without hoses, and add water in the 'in' side, if is powers out the other side, then it's fine. how is your water/coolant mix?

In the fan circuit...You have a temp switch screwed on the radiator, a fuze and a relay in the fuze box plus a fan. Swap the relay with another relay, replace the fuze. The other fan should come on when the a/c is turned on. If you fix the fans and it still overheats, you may have a BLOWN HEAD GASKET. ALSO ARE YOU BLEEDING THE AIR FROM THE SYSTEM? DO YOU SMELL EXHAUST IN THE COOLANT?

Check to see if you have flow through the entire radiator.If part of the radiator core is cool to the touch when the engine is at operating temp, this indicates restricted radiator flow. If the entire radiator core is not allowing water to flow through, cooling will not be at all efficient. Also a good idea would be to purchase a block tester. available at napa and other reputable parts houses for around thirty dollars. You remove a small amount of coolant, and put the tool in the radiator, or pressure tank opening. If there are any combustable gasses present, i'e' exhaust, this would indicate a head gasket breech, (or maybe worse) and would indicate that it's time to stop looking for a simple problems, and get proffessional help. Good luck to you!

If the radiator is filled to the top with coolant and the engine is run without the radiator cap in place, the coolant will expand and spill over as the engine warms up.
