I am actually needing these parts for my 2002 Daewoo Lanos, but the engine is basically the same, and uses the same timing belt and water pump, the same coolant crossover pipe (GM P/N 96180035 or 96273608), and the same hose which goes from the outlet of the water pump to the coolant crossover pipe (GM P/N 96180071 or 90231655).
I am in need of the original spring hose clamp which connects the smaller side of this hose to the water pump (information online says the hose is 28mm inner diameter on this side), and the original spring hose clamp which connects the larger side of this hose to the plastic coolant pipe (information online says the hose is 33mm inner diameter on this side).
Can someone please assist me to find the part numbers for these two hose clamps, so I can order them? Worm-drive hose clamps loosen up due to thermal cycling in this area, and this results in leaks. It is impossible to access the hose clamps to re-tighten them once the engine is assembled, as the intake manifold must be removed.
You can always just use a worm clamp that is the next size up and tighten, then bend the access tightly back over the screw head tightly and zip tie it in place and or tape it so it can not loosen up… Sometimes you gotta think outside the box…
Surely someone here has access to the GM parts diagrams, and can get me this information?
And I regret that the original hose clamps are gone, though in fact I didn’t get rid of them. In fact, when I bought this car, I was super-busy at work, and since I did not have time to do a DIY timing belt replacement, I paid a professional shop to do it, over $1000, and they actually did a lousy job, which I discovered years later, when I took the engine apart to replace the head gasket.
The professional mechanic replaced the original hose clamps with worm-drive hose clamps, and tightened them super-tight to the point that they were cutting into the hose. Also, when installing the timing belt on this engine, you are supposed to set it to maximum tension (indicator on the tensioner points to notch on bracket), rotate the engine a few times by hand, then relieve some tension until the indicator on the tensioner points to a pointer on the tensioner bracket). Of course, they left it at maximum tension, which would have caused the belt to fail prematurely, and ruined the engine. Obviously, once I took it apart to do a DIY head gasket, I put a new timing belt, water pump, and tensioner kit.
Thanks again to whoever can get me the GM part numbers for those two OEM hose clamps. It would be very much appreciated.
