Where is engine block coolant drain plug on a 4.3 liter Chevy blazer?
The engine block coolant drain plug on 4.3 liter Chevy Blazer is located on the bottom of the engine, near the oil filter. It allows coolant to be completely drained from the block during maintenance.
It is located about half way down the block on the drivers side closer to the back. There are two sensors one for the gauge and one for the engine. One (temp. Sensor) is located on the front top of engine by the goose neck for the upper radiator hose. the other (Temp. Sensor Switch) is on drivers side engine block.
The starter motor/solenoid on a 2000 Chevy S10 Blazer is on the lower passenger side of the engine block. If your trying to replace it, first, disconnect the negative battery terminal. Remove the differential carrier shield. Disconnect the bolted solenoid cables. Remove 2 vertical bolts securing the starter motor to the engine block. When reinstalling starter, tighten mounting bolts to 50 Nm/37 lb. ft.
To normally install a block heater you must remove an expanstion/ freeze plug in tighten in the block heater. The 6 cylinder 4.2L engine unfortunately does not appear to have any such plugs. The V8 engine should have a screw in style block heater installed in the left front of the engine block just below the cylinder head.
yes in a way. block heaters heat the coolant in the block there for warming the block up. coolant heaters heat the coolant out side the engine like in the hoses and radiater. and when the coolant gets hot enough it opens the thermosate and starts flowing through the engine..The coolant heater should be hooked into the engine so that it heats only the engine and the heater core. If the coolant heater is trying…
Kind of. There are water jackets inside the engine block and usually the heads of a liquid-cooled engine Water (or coolant) will either flow from the block to the head to the radiator, or from the radiator through the head to the block (a reverse flow design). The latter is better because it cools the heads first and helps prevent detonation. It also reduces thermal shock to the engine block.
What if your 1992 Chevy silverado is leaking engine coolant from the top of the engine just below the distrubutor what is leaking?
There is a heater hose that goes to the left rear top side of the intake manifold and that fitting leaks engine coolant sometimes and it will run down the back of the intake around the distributor. If that fitting is not leaking then the intake manifold gasket is leaking coolant in the corners of it. REplace the intake gasket. That's all that can leak coolant on that year engine. If coolant is leaking out…
