Temp Issues.

Is there a water pump store similar to radiator barn?

 

and I don't remember where I saw the thing, but someone once said that for an auto parts store to have the dual core radiator you want you have to ask for a different type, anyone recall that?

 

Concerning the water pump, what difference is the hub height, other than 7/32"?

 

And finally for right now, since I have a manual transmission, and the radiator barn radiator they say is for my car is for an auto, will that make any difference? What about me having a turbo and its for a non-turbo? Would it just be easier to go to the pick-n-part?

Only automatic Turbo cars were listed to use the Dual core radiatior. I have no problems with cooling on my 89 Turbo using a single core.(actaully, it get's too cool, but that is probably my cheapo T-stat) I think if you just get a new single core you'll be fine.

 

You can use an Automatic rad in a MT, but not the other way round. This is because the Auto has 2 tubes for the trans fluid cooler. Some MT radiators have the bungs for those tubes so you could adapt.

I cannot recall which water pump you want, but it IS listed in the FSM specs in the .pdf files that you can download for the EA82 from http://www.ch601.org/engines.htm . The difference can also be eyeballed; one style water pump has studs on the nose to bolt the clutch fan to; where the other water pump has holes, and uses nuts and bolts to attach the clutch fan. You can look at yours, figure out which you have, and then find a site like http://www.rockautoparts.com or http://www.thepartsbin.com that might show you photos of the prospective parts, and ID it from there. OR try searching the forum; it DOES come up alot. (note: if you DO search, I guarantee you will find comments from me left and right saying exactly what I just said to you )

For the Water pump shaft there is another easy eyeball. The bodies of the pumps are identical. it is just the spacing of the pulley hub on the shaftthat is different.

The 105mm(short) one has barely a 1/4 between the body of pump and the base of that pulley hub. not much shaft showing at all between the body and hub.

The 110 mm(long) one has a good half inch. In my experience, the 110 is the far more common setup for GLs. XTs mostly have the 105. But I haven't been able to find a hard and fast rule about what has what. Espescially because so many of these cars have had motor swaps. I think the difference is based on which of the 2 types of AC setups the car has.

If you ever find yourself replacing the original water pump from your car, make sure that you have the pipe that goes into it replaced too, otherwise you'll spring a leak all over the road!

 

I seriously don't know how many miles the old one had, but it was done. And that pipe was so crusty-rusty that trying to reuse it was a dumb idea... so was trying to RTV it... At least I knew where I could get a replacement.

 

The outside temp right now is, I think, having an effect on overall temp, but after replacing the water pump, it never got above 1/2 on the temp meter at speed and so far never above 7/10 at idle (Tstat opened and it dropped to 3/10). It hovers around 1/2 at idle and just under at speed.

 

I found an old indoor/outdoor digital thermometer that I never used in my old Honda and I'm thinking about adapting that to read coolant temp for me until I find something cheap and more permanent. And yes, it reads to at least 160F (burned my fingers) and I have no clue why I ever needed that thing before, until now.

 

Here's the kicker: all winter long I shivered and wished for a working heater. Today was 82F (according to the digidash ) and the heater made me feel like one of those Nazi's in Raiders of the Lost Ark when they opened the ark and their faces melted off...

 

Now to rewire the aux fan to a cabin-mounted switch and I'll be set!

 

Thanks You all for all the help!!!!!!!
