Timing Belt/Waterpump lessons learned
Just did my timing belt, waterpump, etc and wanted to pass along my lessons learned. I read up quite a bit, but don’t remember seeing these thoughts:
Protect the radiator with cardboard or remove it. I darn near damaged a fin
If you plan to replace the cam shaft oil seals, remove cam shaft bolts before the old timing belt so that you can use the leverage of the crankshaft bolt to hold the pulleys. Alternatively you can use a strap wrench.
If you don’t have a 250LB impact gun, use a heavy duty strap wrench, sand paper, and double sided tape to remove/install the crankshaft bolt
Use a dremel with brass wire brush to do the final clean on the waterpump mating surface. It corrodes and pits due to dissimilar metals between the aluminum housing and the metal/rubber gasket. More then scrapping is needed.
2.5 gallons of anti-freeze are needed
The special snap-on pulley spreader tool works well, but I needed to leave it in to get the belt on. The pin didn’t hold the tensioner back enough. Also, make sure the pin hole is in alignment first.
Pressure wash the engine before working on it. I had planned this, but it was raining/cold the past week.
