SOURCE: replace water pump v6
1. Drain the coolant.
2. Loosen, (don't remove yet) the 4 bolts that hold the water pump pulley.
3. Remove the drivebelt. In order to remove the belt you need to put a wrench on the tensioner pulley to decrease the tension on the belt.
4. Now remove the 4 bolts loosened in step 2.
5. Disconnect the upper radiator hose from the water pump and disconnect the bypass hose from the top of the water pump.
6. Remove the drivebelt tensioner by removing the bolt in the center of it.
7. Remove the water pump bolts. There are 6mm and 8mm bolts, a total of 12 bolts. They are not all the same length. Be careful to note which bolts go in which holes.
8. After all bolts are removed sometimes the pump will require a little whack with a rubber mallet to unseat the gasket. Never pry between the pump and engine block.
9. Before installing the new pump, clean all the old gasket material from the engine block.
10. Use RTV sealant on both sides of the gasket for the new pump.
And............ the rest is just reversing the above except that you can fully tighten the pump pulley before putting the belt back on.
I hope this is helpful.
SOURCE: identified leak in intake manifold
I'am sort of missing something here
Was the radiator blocked or replaced as a guess ?
The thermostat i understand
The heater core by pass i don't,what does that prove ?
The shop says - intake manifold hose.
A hose causing overheating,explain that one.
The finally question
What is your question? Did the repair shop
get lost and ask you for help?
