How much should it cost to replace 2005 Honda Civic water pump and timing belt?

$800-1,000? Sure if you go to the Honda stealership to do it. A mechanic should be able to do it for less than $600. When I had my CR-V's timing belt changed, it was $525. So for less than $600, you should still be getting the timing belt, waterpump, seals changed. Also, since they are doing that, they also change your other belts at the same time. By the way, your Civic's timing belt should be changed every 110,000 miles according to Honda so you shouldn't even have to change it just yet. The overheating could be a bad thermostat. Are your fans working as they should? Do you have a coolant leak? Check your coolant level. There are many things that would cause overheating. If it is your waterpump, then do the entire timing belt service. If not, don't bother with it and save your money unless you want it done now. That's my 2 cents worth.

for the shop about $800 yourself about $100 If you do do it yourself be suree to use a manual(you cann get one from the dealership), and consult someone who has done it before.

Don't listen to everyone who is saying do it yourself. If you cant diagnose those problems yourself you arent ready to replace your timing belt. if you dont have your timing right can will blow your engine within 30 seconds and have to replace the whole thing. You shouldn't need a new belt but if you have a mechanic that is a friend of yours have them take a look at it. Alot of shops try to rip people of and sell them things they dont need, dont fall into their traps. Hope this helps!

it does sound logical. you should change the timing belt every 70-80000 miles. your water pump is probably on its way out.

yes, about 800-900 at the dealer. call all dealers for discount, they usually have like 10% off for timing belt job.

You're overdue. It will run apprx $800 - $1,000 Shop around.
