Is it easier to replace the water pump and Thermostat when replacing the radiator?

Anthony199 · 07-31-2019, 11:02 AM

Hello,

I will be replacing my radiator tomorrow on my 325i 2006. I'm wondering if it's easier to replace the WP+T since there will be a lot more space towards the front of the car?
If the only benefit of replacing the WP+T tomorrow is that I won't have to do the coolant bleed twice, then I won't do it.

Thanks!

Can't comment on the water pump. But....it is easier to do your tensioner and serpentine belt if those need replacing. Lot's of room with the fan off. What brand radiator are you replacing with?

Behr radiator is the replacement.
I have already replaced my tensioner and belt about two years ago, I don't think it is necessary to replace again.

The waterpump and thermostat are a real pain to do and the radiator being out will not help much with room. With that being said, it's not a bad idea to replace it if it has 60,000+ miles on it

Won't really help much with room for those two, if you are getting up there in miles then yes might as well do it, but if there aren't too many miles on them then I wouldn't bother

The previous owner replacer the pump at about 40k miles. I'm at 135k approximately, so it's a time bomb haha
Waiting for it to stop working so I can tow it to the shop. Seems like a though job honestly.

If there's 90k on them like your previous post stated then yes change them out.

The only real help is you have to dump and refill coolant for both, otherwise no real overlap in the jobs.
