how do i replace a front crankshaft seal on a 99 mitsubishi mirage
Remove the serpentine belt. Remove the harmonic balancer. Pry it off the crankshaft. Install new seal, replace balancer and belt.
Cost me $185 at the dealership.
You probably need to replace the crankshaft seal
No you can not. It is a solid round seal that slides over the back of the crankshaft where the fly-wheel bolts up to the crankshaft.
Should pull the drive pulley and then you can pop off the old seal with a screw drive and press in the new seal.
First you will need to remove the Harmonic Balancer pulley from the engine. This may prove to be difficult being the bolt that holds the pulley on is tightened to 220ft lbs. once the bolt is removed the pulley should just slide off. behind the pulley is the front crankshaft seal, use a good seal remover tool to pry the old seal out. reinstall the new seal with a seal installation tool. make sure the crank pulley is tightened back to 220ft lbs.
Need more info like the year, make, engine size and front or rear crankshaft seal.
You need to remove the belt pulley, then timing belt, its pulley sitting on the crankshaft. After that you will gain access to the seal. The seal has to carefully pried out. Make sure that you do not scratch the crankshaft surface as well as the seal seat in the engine body. Put a little bit of clean oil on the seal before installing it, it will make your life significantly easier. Make sure that you do not damage new seal when you are installing it.
You will have to replace the rear main seal. This will require that the transmission be removed.
Gas Cap is not on tight, or the seal leaks and you need to replace the cap.
