Pressure {screening|tests|examining} the cooling system is a simple process to ascertain where {a drip is|an outflow is|a flow is} located. This test {is merely} performed {following the|following your} {chilling|air conditioning|cooling down} system has cooled {adequately|completely|enough} to allow you to safely remove the pressure cap. Once you are sure that the {chilling|air conditioning|cooling down} system is {packed with} coolant, a cooling system pressure tester is attached in place of the rad cap. The tester is than pumped {to develop|to produce|to formulate} pressure in the system. {There exists a|We have a|There is also a} gauge on the specialist indicating how much pressure is being pumped. You should pump it to the pressure indicated on the pressure cap or to manufacturer's specs.Pressure test and Internal leak test
When pressure is applied, you can {commence|get started} {to consider|to watch out for|to find} {leakages|water leaks|escapes}. Also watch the {measure|see|judge} on the tester to see if it {manages to lose|seems to lose|will lose} pressure. If the pressure drops {greater than a|higher than a} couple of pounds in two minutes, there is likely a leak somewhere that may be hidden. It is not always easy to see in which a leak is originating from. It is advisable to have the vehicle up on a lift so you can look over everything with a shop light or flashlight. {In the event that|In the event|If perhaps} the heater core in leaking, it {may well not|might not exactly} be {obvious} since the {primary is|key is|main is} enclosed and not {obvious} without major disassembly, but one sure {indication is|signal is} the unmistakable {smell|scent|stench} of antifreeze inside the car. {You may even|You can even|You might also} notice the windshield steaming {plan|program} an oily residue.
Internal {drip|outflow|flow} test
If you are losing coolant, but there {are not any|will be no} signs of {leakages|water leaks|escapes}, you could have a blown head gasket. {The easiest method to|The simplest way to|The ultimate way to} test for this problem is with {a burning|a combustable} leak test on the radiator. {This really is|This is certainly|This can be} accomplished {by using a} block tester. This is a kit that {works|functions|executes} a chemical test on the vapors in the radiator. Blue tester {liquid is|smooth is|substance is} added to the plastic container on the tester. If the {liquid|smooth|substance} turns yellow during the test, then exhaust {vapors are|emissions are|air are} present in the radiator.
The most common causes for exhaust {vapors|emissions|air} to trouble the rad is a blown {mind|brain} gasket. Replacing a bad head gasket {needs a|takes a} major disassembly of the engine and can be quite expensive. Other causes include a cracked head or a cracked block, both are even more {unwanted|undesired|unfavorable} than having to replace a head gasket.
