What is the r&r time for a 99 Toyota Celica gt. Timing belt, water pump ect

if you are doing it in the yard and never done one,probably around 5 hours. if at the shop around 2.5-3 hours. just replaced mine on 98 Camry(same kit as your Celica) same engine.you can get the kit at RockAuto.com,>>DAYCO WP199K1A ,water pump,timing belt,camshaft belt idler,camshaft belt tensioner,2 tensioner springs,wp seal,wp gasket,complete instruction sheet.this kit is $58.79 plus $7.99 shipping,for a total of $66.78 plus sales tax(bout $70.00). where I live,Autozone will match the Rocks price,same kit(Dayco)(it's $113.99 plus tax at the ZONE,BOUT $120.00). all I have to do is print out the Rocks page/price,and the ZONE WILL MATCH IT(SAVED AROUND $50.00!!! I have been doing this for a while now.

Good idea to replace the camshaft oil seal and the front crankshaft oil seal while you're at it. Don't know your skill level.
