K Engine Water Pumps - Differences.

[philbey]

Folks,

 

I've got a KE10 waterpump in my car and the bastard has a really long nose on it - I'm keen to move my Thermo to the back of the radiator with a shroud, but I'm really going to struggle to gain space.

 

Can anyone tell me if the later model corollas ran shorter noses on the waterpump? Mine is long and runs a pulley with quite a lot of offset on it to line up with the crank pulley. Given that later models ran the clutch fans I'm thinking they maye be shorter. Mind you they also have longer engine bays....

 

Let me know people. Cam, Felix, i'm looking in your directions, you always seem to know this random shit...

 

Thanks,

 

Philbey.

G`day mate, my 4kc runs a thermo clutch fan and the water pump measures 96mm from the block to the front of the pulley. (where the fan bolts on) The pulley measures 43mm from front to back.

Hope that helps, Old Fella.

I recently helped out member 'Banshee' with a ke1x water pump. Might pay to PM him and ask what was the end result, but IIRC you can swap a '30/'55/'70 etc type pump onto it as long as you use the matching pulley - As the crank pulley is always in the same spot on all K's.

 

So yeah use a long nose pump with a shallow pulley, or shorter nose pump with the deeper pulley. PCD's on the pumps also change so this is another reason to use the appropiate pulley. :wink:

 

FYI though - We were trying to get his car going for a cruise that weekend, which we did. BUT the '55 fan (IIRC) he was using was very close to the radiator. Half way through the cruise he pulley out of a street, engine moved just slightly pushing the fan into the rad which ate its way into it and dropped all its fluid. So double checking this gap would be well worth while.

What I encountered was this:

 

I run a 5k in a KE18.

 

Original water pump was likely from the original 3k, as it was a very short neck with a shallow pulley. This allowed the fan to fit between the motor and original rad. When I replaced the pump with a unit from a newer 5k motor, it was a much longer neck on the pump with a deeper pulley. Also, the four mount screws were a slightly larger radius. This meant i had to swap fans too. BUT, I then ran shit out of room, and as TasRX stated, it ate its core when the engine shifted forward on a 2nd gear downshift. This caused the fan blade to nick the bottom of the top tank, folding a shard of plastic inwards and mincing my core.

 

What i have done now is fitted a KE70 rad, removed the mech fan, and fitted a front mounted thermo fan. As i was still shit out of room for even a thermo fan to squeeze in there.

Tom it looks like you have already got a short nosed pump.

[SLO-030]

can't you make/ have made a shroud for the front if it and the thermo bolts to the shroud?

 

Probably out of sheet metal. Powdercoat/paint it black and you'll never see if from the front.

 

I was under the impression that the KE70 pumps had a shorter nose and shallow pulley.

Hi,

Ok water pump. You have a KE1X pump by the look of it.

 

KE1X I find all have the motor sitting very close to the radator I have found (my KE15 and my old KE11 did).

 

Also the KE1X had a flat metal fan that was flat metal that was twisted at both ends don't have a photo handy on me. Prone to cracking and dangerous. I found with a plastic KE30 fan would nearly NOT fit in the KE15. A clutched fan NO WAY.even with a early K KE1X pump.

 

But Below is a scan of a Toyota book I have for rebuilding late model KEXX pumps and that. As you see you press the front flange on. If your having issues with your fan belt going straight need more room just try pressing your flange on the front of the pump on more.

 

Also Why run a fan from the back I run a HUGE thermo on the front of my KE15 and seems ok.

 

Also look in my KE15 thread page 1 or 2 a good thin fan that Redwarf uses on his rally car is listed. Try sourcing one of them as I can't for the life of me remember it atm.

 

But below is the scan:

Cam have you actually driven your ke15 yet? Hopefully the front mounted fan will work out for you.

 

The missus' ke16 used to have a thermo fan on the front of it and would get hot in the middle of summer. I took it off and fitted a plastic fan and the thing ran cooler. No idea on what the fan was from, it just fit and is the same as I have run on my ke15 with no clearance or overheating issues... even on a hard run up Mt Glorious on a 40 degree day.

 

The biggest cooling issue I've had is chewing lower radiator hoses.. :wink:

Hi,

Felix yes drove it a bit in hiding to test out thermo sensing switch I have and with a bad tune 5K pinging kept cool so ill see how I go.

 

As on my KE30 I run a front mount fan off a commodore fits straight on no issues parked in 40 degree traffic on motorway in grid lock so hope KE15 performas the same.

 

Also I have a KE20 radiator in my KE15 that has been re-cored. Is thicker than a normal KE1X radator so I have less room.

 

As when I got the car the original owner had a KE30 plastic fan on it and it ate the radiator :wink:

 

Cheers

Cool.

 

You have to pick and choose with the plastic fans. I've got no idea on the original source of the ones I've run but the offset is correct. Interestingly both cars had different PCD's and nose diameters on the waterpumps. Can't run them with the double row crank pulleys though.

 

Just enough room...

[philbey]

Thanks old fella, I'll measure mine and compare.

 

Mine is a KE10 pump, it was brand new out of the box, finding a fan to fit was a nightmare, hence I'm running electric.....

 

There are 3 different PCD's on these pumps, KE30/55s are different to the 70's. Mine is different again, in between the two IIRC, and the only fans that fit are original 2 blade steelies. To get that pulley to fit I used a chainsaw blade file to open them out.

 

I did notice that you can press the boss down on the shaft but that means I've got to go through the pulley rigmarole again. I'll do some measuring and see what length pump I've got.

 

I'm running a 12mm spacer between my rad and the front panel, I'll be cutting my removable radiator support and sectioning it so I can shift the whole rad forward again. It's a KE20 item and isn't an ideal fit.

 

As for shrouds on the front, no go - If the fan fails, you lose way too much forward motion airflow to cool it.

 

It's a Davies Craig fan, its narrow and it moves a shitload of air. Just as the warmer weather is closing in, I'm noticing higher temps. I'll fit a little header tank and I'm considering some cooler plugs to see how that goes. It also runs a little on the lean side at idle:

 

slight lean idle + traffic + no forward movement + stock heat plugs with high comp = philbs gets nervous (1 headgasket down already!)

ive seen at least 3 different pumps, maybe four, as long as you get the matching pully they all fit, but the piping for the heater can change from pump to pump
