IS this a DIY job? I need to replace my thermostat housing and water pump. I also need to replace the o-ring and gasket. Thus, do I need to replace the thermostat as well if I replace the thermostat housing?

Secondly, should I go ahead and replace the upper and lower rad hoses and the radiator? I was thinking of purchasing the cooling system from CMUZZY (supporting vendor) for $250.00. I have 35K on my car right now. I know I do not need to replace the radiator; but, should I go ahead an do everything?

I have the Bentley's....is everything CORRECTLY detailed in Bentley's. I've found some discrepancies using the Bentley manual before.

Plus, how long of a job is it? Is it a 4 hour job doing it myself or a little bit longer? Do I need a ramp or can I use a jack and jack stands to do everything?

P.S. -- please email me if you've done it before, so if I have questions, I can ask you, if you do not mind since bf.c will be going down soon.

Thanks!
