    Waterpmp AGAIN!

    k so 11 months ago I had to get a new waterpump, leaking, no big deal and $629, and 3 months after again it started leaking. GM tech guy also replaced the seal on the plate behind the waterpump and again another new waterpump, covered under warrenty. Now it's leaking again and I am having only GM parts installed at the Cadillac dealership! Getting more than a little fed up and was wondering where these things are made already! China?! My warrenty better cover this tomorrow because we're talking about probably near $700 now because of bad parts

    oh great just found out it isn't the waterpump, it's the heagasket. Total cost to fix after tax is $2481.

    Ouch!! I'm glad I can do my own water pump, it's actually become quite easy over time! I've done it when I had my 88 Eldorado, my 91 Eldorado, and my current 95 Deville! Lots of little nuts and bolts but not too difficult! Sorry to hear it's your head gasket Ralph!!

    Get a second opinion. Headgaskets rarely fail on 4.9 engines. As for water pumps, as soon as you replace the original pump, you keep replacing them again and again. AC Delco waterpumps are made in China.

    thanks. Well it was at rhe Cadillac dealership and I snuck back to the shop area ( they don't like that) and talked to the mechanic and he showed me how he tested the coolant and there are Hydrocarbons, or something in the coolant, indicating a blown gasket. He said the head gaskets are made of tin. So what is happening is there is some excess pressure in my cooling system while it slowly gets contaminated with these hydrocarbons, or whatever. The leaking was caused by the rad cap bleeding some off he said. I just went down to look at everything and the upper hose was sucked flat (maybe from the pressure test) and the coolant level was about 5 inches low. When I opened the rad cap to top it off, there was a whoosh of air and the hose took it's normal shape again. He said I could drive it but if it ever starts knocking then the engine has probably already seised up. Parts will arrive in 2 days or so. fun fun

    negative pressure in the cooling system is never a good sign...

    I hope all goes well and this takes care of the problems.

    Yeah no kidding. Mine needs to be replaced every 2 years or so. It always rusts at the gasket and then starts leaking. I keep a spare one around now.

    Caddy dealership called, ran into a snag, won't be ready until Monday. The kit was supposed to have 2 intake gaskets (I think he said) so that will come in seperately and there is another rubber piece they don't make anymore because the car is so old, a rubber elbow, some kind of gasket for the valves he said. But the good news is it won't be over the price they quoted in the estimate!

    Got the car back. The power steering reservoir cap wasn't tightened. a bolt was missing on the valve cover. I can't believe they had to drain all the fluids including the engine oil! They broke a couple of exhaust bolts but I guess that's normal.

    ok so everyday the upper rad hose is a little sucked in on itself, I release the rad cap, it springs back to shape and the rad level is always a few inches low! Also the coolant reservoir level is on FULL and never goes up or down! I wonder if the guy plugged it for all the work and forgot to reconnect it. Found 2 more bolts the mechanic didn't put back and one is to hold the rear fuel rail from moving!

    Make sure the hose from reservoir to the radiator neck is not plugged. You might want to replace rad cap, they go bad. Broken exhaust bolts will create exhaust leak. You can hear it. That leak can affect oxygen sensor input as well. Not a good mechanic , I guess.

    guess what. Today I lifted up the reservoir and the hose was twisted! As soon as it untwisted the level increased and I heard another whoosh of air! I hope this takes care of the air in the system but I called yesterday and they said I can expect air for about a week or so. It's a new rad cap. Also they supposedly changed to all new exhaust bolts as they were part of the kit I had to buy
