HT4100 4.1, 4.5, 4.9 Discussion, ACDELCO best water pump? in Cadillac Engine Technical Discussion; What's the best water pump to buy without breaking my wallet? I want to go with ACDELCO. I see two ...
I have heard alot of complaints about cheap replacement water pumps. My car sat in moth balls for 6 years until 2 years ago. The gasket was leaking, but the pump was good and I just went ahead and replaced it. I used to deal alot with a GM dealer, so I went ahead and got a new pump from there. Nearly fainted when I found out how much, but the parts guy asked if I want the good one that will last or the one if I'm getting rid of the car. GM dealers will always be more expensive, I didn't know about rockauto.com at that time either. I bought the expensive one and haven't had any problems yet. I also did not want to do the job over again for quite awhile.
Sometimes you have to be careful as price doesn't necessarily dictate quality, but rather warranty. A lot of times, the two parts are the exact same piece, the more expensive having a significantly longer warranty than the cheap one.
Well the damage is done part in the mail. Will keep that in mind for future reference.
But anyway just bought a t45 torx bit. (too broke to buy a set) a new serpintine belt and a tensioner pully for a little while im at it preventive maintenance. The pully had a little play and was suspect for the grinding noise I've been hearing.
So far this project has run me a little over $200 not too bad seeing as im doing it right. I want the best for my ride but I've been doing some shopping around to get the most bang for my buck.
Still need to get some coolant and a good seal for the gasket but if all goes right i should have every thing done this weekend.
I have a scraper that has a holder for a razor blade. Has a long handle and I think I got it at home depot years ago. If you want to scuff it a little to clean it good, get a piece of sand paper and cut a piece to fit over the end of a paint stir stick. I only mention the goofy tools with long reach because my experience is a little tough getting enough clearance between frame and engine. I think I may have taken the alternator off also. and the cruise bracket. and I also took the rh front wheel off. and the plastic splash shield. I tend to get carried away tho.
I know a former GM tech who says you can unbolt the front motor mount and jack up the engine for better access to the pump. Maybe the rear also, I cant remember... Either way, the motor mount nuts are easily accessed from below the subframe, 2 per mount.
I like to use this on gaskets, especially water pump gaskets since using a conservative amount of sealer is critical. I've even used it on head gaskets. Cheap insurance.
As far as removing old gasket material: Acetone and elbow grease, mostly the grease.
