    cost of replacing coolant system.

    About how much would it cost for me to replace a water pump and a leaking thermostat for a 1997 528i, if I were to bring it into a shop? I just want a rough estimate of what to expect. And if its too expensive do you recommend that I just try to replace it myself? How hard is it to replace a water pump and thermostat?

    Discuss.

    If you have the tools and ability do it yourself, you'll save a lot of money. Water pump and thermostat are right up front and fairly easy to get to.

    yea i went to a bmw repair shop and the guy said 900 to 1200, does that sound reasonable? or should i just try to repair it myself for that price?

    Ok, let's just talk parts first:

    1) water pump $70
    2) thermostat $30
    3) thermostat housing (aluminum one) $60
    4) bmw coolant - $15

    Bare in mind, those are high estimates, so total is about $175 in parts. Round that up to $200 just so you'll be happy when you find out you'll spend a little less.

    Get a quote, subtract $200. Then ask yourself, for that amount of money, is it worth going out and buying a few tools and spending a few hours to do this yourself.

    I did the replacement myself and saved only $150 from an independent BMW shop. That was with a new radiator, new hoses, etc. but no waterpump. I put in a composite waterpump and expansion tank which matched the quote. Next time, I would let the shop do it and also deal with other unexpected problems.

    how much did it cost you for this job? was it anywhere near my estimate of $900-1200?

    Two independent BMW shops quoted me about $450 to replace a thermostat, aluminum housing, radiator, 2 hoses and coolant. It costed me about $300 for a DIY plus a pressure test. I added a composite waterpump and expension tank, bringing to a total of $450. It was most time-consuming of several DIYs I did as a first-timer.

    Wow, thats a great deal from an indy, I would have let them do it too. Unfortunately around here they'll charge from $1,200 and up. I'm doing the cooling overhaul in a couple of weeks myself, I've done everything else so I figure I can handle this. Tons of DIYs out there to help out, I figure around $300 for everything.

    i would have to agree, stormtrooper's indy shops quoted him an awesome price. i live in southern cali too, and there's no way i'd get a quote that low, including the new radiator. However, the $1200 and up quote seems a bit ridiculous... for that price, I'd expect hot naked chics for their mechanics/techs.

    Didnt know it was cheap after the same shop gave me a $1,500 quote for repairing A/C.

    I'd think if the savings doing DIY is up to $250, let the shop does the replacement. Thats me.

    I replaced my t-stat and t-stat housing in about 2 hours from start to finish. That was the first time I ever worked on my BMW other than an oil change. I was hesitant at first but there are some great DIY sites out there. I did buy the $30 slim line wrench but the entire job probably cost me around $100 for the t-stat, alum. housing and coolant.

    Update: My Nissens only 1 year old was leaking for a month. I took my car to the shop and bailed out at a total cost of $802 for labor and a new radiator. I'm doing a DIY spending $150 this time.
