so my water pump went on the club drive the other day. i was still able to do about half the 5 hour drive, and i had a water pump waiting for me when i got home. so i set to work today to pull it out, got all but 3 bolts out, then i look and see an allen key and i think "thats strange..." so i wip out a 6mm allen key and pop it in there. it has a little flex and then shears off with the end stuck in the bolt. i can't pull it out of the nut, and i can't get the nut out. i need my car tomorrow afternoon, and im not really sure what to do now... anyone got any bright ideas for me?
edit: i forgot to mention it was a craftsmen prof. key, and i'v tried drilling it with a small bit and it just snapped like a tooth pick. i tried low and high rpm's before it broke, and it only made a small pin prick in the key.

well after some consideration im going to weld a piece of metal onto it and pull it out. heat it up and see if i can't get it to come out. ill let you guys know how i fare.
-
yay! so i figured what the hell its still warm out, i can get enough light with a flashlight. so i got her welded up and got the bolt out. a few light taps strategicly lossend the pump and its out now.

Congratulations! You talked yourself through the whole thing ;)

Consider yourself lucky that your waterpump job didnt end up as badly as mine.

Moral of the story, change your coolant regularly kids. The previous owner of my car didnt.

I was fortunate enough to not have any issues with the water pump R&Rs when I had to perform them. I was thankful as I replaced mine in the parking lot at night with a flash light last winter. NO FUN at all.

hahaha i know... i used some heat, and slight tapping of the hammer in all directions and it loosened it up. it was stuck in there pretty good at the start... but it came out whole. the previous mechanic didn't use anti sieze on the bolts... moral of the story? do it yourself.

alright so new problem. i did all this work because the temp wasn't rising above the 1/4 mark. so i replaced the water pump and T-stat. now i took it out and beat the shit out of it for about 30 min and it only made it a hair above the blue mark. am i just needing to make more power so it runs hotter :) or what should i do?

Are you sure the temp guage is functioning correctly? (ie. grounding nut on insturment cluster)

yeah it works fine. its steady, works properly. my fan didn't even get a chance to kick in on the medium seetting which should have been about 1/4 way up on the temp guage. (it has its own temperature unit)

Faulty t-stat perhaps.

yeah... i just bought it yesterday, i think im gona take it back and try a new one.

Let us know how the new one works out. :)

Yeah, has to be T-Stat. You are using the 88C one, right? That is the 'proper' one.

well it had an 88c one, but they gave me a 79.5 C one, which puzzled me, but thats what showed up when he looked up the car.
-
alright so i put a new one in ($50!!!) pretty freakin expensive unit, it was imported from germany:) so now it temp went a bit higher, but (with the fans off) i cannot for the life of me get it to rise above the 1/4 mark!!!!!! what the hell is going on?
-
Are you putting it in facing the right way, o-ring & everything? It should just set right in place, with the spring inside the cylinder head. If it is staying that cold (which mine used to when the t-stat dies & stayed open), it is either the t-stat, or there is somewhere else that a LOT of coolant is bypassing the t-stat. Is the housing damaged inside at all? There should be a little groove between the inlet & outlet side of the housing, make sure it is cleared of gunk. Also check inside the head where the t-stat site to make sure that there is not some sort of damage allowing the coolant to flow by the t-stat.
-
there is no damage anywhere, and the passage your talkinga bout, thats on the fitting right? that things is clear as well. i tried 2 different T-stats. the spring is facing inside the head, i tried flipping it... but that reverses the problem as it totaly blocks coolant flow... this is the second brand new stat i'v tried... and im pretty sure coolant couldn't get through anywhere else...? its not burning coolant either as it maintains proper level... so im lost.
