i'm a bit confused.do you have also make these changes or is just changing the timing belt alone sufficient?What other things to change when changing timing belt?It's the water pump that you mean not the fuel pump.If you have plenty of money change the lot but i would never throw good parts away for the sake of what if.Would you change your brake shoes if they were only half worn, just in case. Would you change your radiator if it was 5 years old.No of course not ! ! If the water pump bearing shows no sign of wear or noise and a decent mechanic will be able to tell,leave it alone.A new water pump can leak and if the timing belt is adjusted too tight the bearing in that can fail just as easily as on an old one.What other things to change when changing timing belt?the water pump is driven off the timing belt in many vehicles. this is true it is good to replace that as well. they have bearings and will only last so long. it is so hard to get to them you should replace them any time you have them in reach. its vice versa with your timing belt. if you had to replace your water pump, replace your timing belt. timing belt faliure can be detremental to your vehicles head and valves. do not ever put off routine maintenence for the timing belt, recommended 80k miles on most vehicles. if you do to save a few bucks you will lose much more than that when it breaks and destroys your vehicles top end.
just watch out for the mechanic charging you too much on labor. if he will replace your water pump there is no need technically to charge you for the timing belt labor, because to get to your water pump you must remove and replace your timing belt. so make yourself aware of this, and try to reach a fair agreement with them.What other things to change when changing timing belt?When replacing a timing belt,buy the timing set.This includes (in most cases)The guides,the idler,the tensioner and/or the sprockets.You also need to replace the water pump and crankshaft seal,which usually comes in the timing cover gasket set.What other things to change when changing timing belt?with your astra you buy a timing belt kit which includes the pulleys tensioner and the cam shaft seals always replace these parts all together and the water pump as well is a good thing to change not really expensive but if the bearings break then big problems the job should take around 5
in the last week i have worked on 2 of these cars one was a precaution and the other the tensioner had seized and stripped the belt causing valves to hit the pistonsWhat other things to change when changing timing belt?Timing belt and water pump because the timing belt drives the water pump.
