so changing the waterpump and doing timing belt too iv hit a snag where the water pump pulley is stuck to the pump even though iv removed the bolts that hold the pulley on. same with the crank pulley iv got the crank pulley bolt off but the pulley is still stuck on and pulling it doesnt seem to get it loose. any ideas on what i can do?
pics attached.

If the pulleys are keyed (the crank appears to be), then maybe it's just a close fit. A three-armed puller would probably persuade them off. Be careful, it shouldn't take a lot of tension. If you find you're having to really crank on the puller bolt, STOP or you may bend the pulley. Ask me how I know. Other pulleys may be press fit on, and need a puller that grips the pulley hub.

Will try some penetrating oil. Those pullies last came off 13 years ago

Try SOFT taps with a heavy hammer. Alternate positions to make it rock a little each tap.

Combine the 2 tips above-the tapping motion will help the penetrating oil get into the pulley bore and will help it work loose.

For future reference, I would take a pry bar and pry behind the pulley and hit the shaft with a hammer. Works every time and no chance of bending your pulley w/a puller.

Thanks. Dunno what to do with waterpump pulley. I think the entire pump can come out with pulley attached. Will have to take the cam belt off first and the tensioner too.

In many cases, the pulley is not intended to be removed in the field. The pump and pulley are a unit.

The one on this car is supposed to be a removable pulley that then transfers over to the new pump.

If you can get it out of the car it will be much easier to remove.

It looks like now that you have the crank pulley off, the lower timing cover and the timing belt have to come off next to be able to unbolt the pump.

yep next step take timing belt and its pullies off.
also the crank pulley is a bit rusty, is there any issues with wire brushing it and hitting it with some rust converter and a coat of paint? or is that not advised to do on it?

took the belt off and the entire waterpump with pulley attached. also i think i solved the issue thats plagued me for over 3 years. constant high rpm driving causes engine temperature to rise. temperature drops back down if coasting in neutral or top gear is engaged:
new pump on and played it smart by pressure testing the system before fitting cam belt back on.
new belt has some slack between the camshaft pulleys, i have read i need a sprocket holding tool to loosen the sprockets and then tension the belt. so tool is now on order.
