Amarok Secondary Coolant Pump - I Almost Messed Up!

Faulty auxiliary or EGR coolant pumps are common on the VW range of vehicles, as well as other manufactures. You may see a fault code P149C or P261A come up on the scan tool relating to this problem.
I was surprised how little time the repair guide gives for this part replacement, but I quickly realised that I had been looking at it all wrong!

These pumps are notorious for falling apart - I have replaced mine 2 times within one year.. the first one died what was probably the normal death by wear and tear, it blew the fuse and threw the car in limp mode. I replaced it with a genuine pump from the VW dealer - this new pump lasted about 1 year and failed after my cooling system really got its jo cut out for it, when I was driving up a steep mountain in Italy, during a scorching hot summer (outside temps about 40C). My theory of why the second pump failed is that the electronic circuit simply got to much heat, the little heatshield did not help enough under these conditions.. So I think there are 2 types of failure mode for these pumps; general wear after years of service, and electronic failure due to excessive heat.. now I carry a spare pump on longer offroad trips as its a relative quick fix that can be performed anywhere with a few handtools. I am considering if it would be possible to relocate the pump a bit longer from the engineblock to help it cool off better, or even mount a small 12v fan directly in front of the pump, to help with driving in hot climates.

Sounds like you have had your work cut out! Yes, manufacturers come up with so -called solutions to problems, but only time and major mass testing proves it's true worth. Let us know if you do any modifications as you have suggested. Thanks for your comment 😉

Thx MM. Good info. Interesting to see the inside of the pump too.

[@MiracleMAX]

Hey Nigel, I always like to pull things apart to see how they work.......especially when I don't have to put it back together. It's also a good opportunity to make a training resource for the apprentices. 😉

[@predragbogunovic5151]

Ive got 1.6tdi polo and i have gone through a few of these pumps. the original one lasted for about 6yrs then every other one lasted less than a year... the very last one i opened up the bottom (electronics part) and saw that the wire connections to the connector were fried (one of them was) i then proceeded to solder a bit thicker copper wires for all 3 connections (- + s) then used basic bunnings silicone and duct tape to put it back together and its been about 2yrs now no engine light no codes... NOTE the mechanical part of it, the propeller, was rattling but i reckon it can work like that although it is not perfect.. i think their main issue is the tiny connector wires that burn quickly so if you dont want to spend $400(genuine) for a new one try what i did.

[@MiracleMAX]

Did you fit genuine ones? Well done for thinking outside the box 😉👍

I always throw away those spring hose clamps too, I hate the stupid things.. we've all started pulling stuff apart only to find we were doing it wrong, I done it the other week on my wife's yaris.. I've had some fun with that thing, a rat chewed a coolant line and it got so hot the head gasket failed so I got new head bolt's, gaskets and skimmed the head and when I went to fit the head I got all the bolt's tensioned and done the first 90 degrees on bolt 1 and only got to about 60 degrees on bolt 2 when the bloody head broke off the bolt 🤬 I'll never use durapro bolts again, now I have to stuff around with the supplier and no doubt I'll be the one stuck with the cost of yet another head gasket

[@MiracleMAX]

Hey Mark, Sounds like you've really copped it! Getting quality parts is a real problem. I'll have up a video in a while about a nightmare of a fuel pump being replaced with a faulty new pump. Makes our day interesting....😒

[@markshort9098]

@@MiracleMAX yeah I had a problem with a new holley fuel pump on my 1979 f100, it worked fine until I got half an hour away and then it'd play up.. the symptoms look like ignition and I was chasing my tail for a while until I run a fuel line into the cab and stuck a guage on it and just drove up and down the road close to home until it played up.. the fuel pressure was going from 6psi down to -3psi as soon as it got heat soaked so I had to try to find a genuine fuel pump which fixed it.. I've had to many problems with holley stuff so I'll never buy it again, the same can be said for msd stuff, I ended up going back to the old points system because it doesn't let me down

[@MiracleMAX]

@@markshort9098 Wow, sounds like you've had some real fun! 😉

[@Jetpropbill]

What scan tool did you use? And were you able to turn on the pump with your OBD2 scanner?

[@MiracleMAX]

I used the GScan 3. kzbin.info/www/bejne/pKWXZ4WMedufjqM You need a bi-directional scan tool to be able to turn on the pump. A simple OBD scanner does not do this. Thanks for your subscription 😊

[@deangibbons3487]

Thanks for this. Did you have to clear the fault code or did it clear itself?

[@MiracleMAX]

After repair, it's always a good idea to clear the fault code and do a rescan

[@robertgibbs6920]

Hey MM will the ancillary heat pump throw up the same fault as the coolant pump? I just replaced my pump (the same one as you did) and a week later I got the same fault back and fuse blown. So trying work out if the heater pump will cause same issue or a relay?

[@MiracleMAX]

Hey Robert, If you have an electric coolant pump and also an auxiliary coolant pump, these will have individual codes. The only reason a fuse will blow is due to excessively high current, beyond what the fuse is rated for. You have to look for that reason. Get an accurate wiring diagram, carefully examine where the pump relates to the blown fuse. Carry out a detailed visual examination of the wiring loom for shorts to ground (rubbing through). Let us know how you go with your investigations 😉👍

[@robertgibbs6920]

So replaced the pump with a goss pump Fault has gone and no more blowing fuse. The pump from eBay had started to seize up and was hard to spin when I applied to a 12v battery to test, I believe this was causing the excessive current draw and causing the fuse to blow…

[@MiracleMAX]

@@robertgibbs6920 Thanks for sharing Robert. Another reason for paying extra for quality parts. Well done! 😉

spring clamps are better for hoses in heat condition because adapt itself the screw clamps might leak

[@kurtbahadur6912]

Good morning sir wats ur advice my 2016 amarok starring is really hard an the i hav to keep adding coolant every 3 days

[@MiracleMAX]

Hey Kurt, I would start by finding out where the coolant is going. Are you able to pressure test the cooling system? If there are no external leaks, you would consider a blown head gasket. Are the glow plugs OK? That could explain the hard starting if you had an external coolant leak. Is there bubbles blowing out in the radiator with the cap off and the engine running? Make sure you do this safely as hot coolant will burn. Here are a few techniques that might help you diagnose if it is a head gasket or not kzbin.info/www/bejne/fZu9gpmDeceCeNE kzbin.info/www/bejne/hWjXm39oitappLc

[@MiracleMAX]

If the fuse is blowing, it must mean you have a short to ground. This must be repaired.The fuse is designed to protect the circuit, so if the short is repaired, you may find the new pump will be OK

[@FTubex]

Hi I got Audi A3 8v 1.6 2013 I changed timing kit (new water pump replaced too ) also changed coolant bottle as well as cap twice but whenever I drive car for more then 1 hour every two or 3 weeks coolant leaking from overflow. Inside temp all ok no overheat also did pressure test headgaskit looks ok, no engine light. Any advice please

[@MiracleMAX]

Was it overheating before? Does it have any fault codes shown on the scan tool?

[@FTubex]

@@MiracleMAX no fault codes . Temp inside fine don't show overheating only time I notice when coolant leak also heater inside car works fine when I switch the engine off the fan runs for 5 to 10min (3 to 5 times a week), coolant only leaks from overflow hole (pipes all ok no leak) Coolant bottle replaced twice The coolant bottle after 20min drives gets very very hot you can't even touch but inside car temp stays normal One garage told me to change the thermostat as well as the pump on your video and let's see , so I thought I can ask for any advice Leaked after 3 weeks yesterday since I replaced the coolant bottle cap for the 2nd time, The coolant level is now in the middle since it last leaked ( before the leak had extra coolant in it) Coolant leaked almost 7 to 8 times in total since I purchased the car 3 months ago, The coolant level after the leak still stays minimum or a little bit more then the minimum level

[@MiracleMAX]

@@FTubex Do you fill the coolant bottle to between the minimum and maximum levels when cold? Is the problem that coolant is getting so high in the bottle that it is coming out of the drain out of the top of the bottle? Does it have excessive pressure built up in the cooling system? Is the bottle an overflow bottle or an expansion tank?

[@FTubex]

Yes i fill it between minimum and maximum when the engine is cold. Coolant bottle gets leak from the overflow hole on top under the cap. The bottle I got is an overflow bottle 2013 Audi s line 8v UK model. Today when I started in the morning the coolant low level sign came up on the dashboard so I filled the coolant again

[@MiracleMAX]

@@FTubex That looks like an expansion tank, not an overflow tank. This has the pressure cap directly on top of the tank. The cooling system must be building pressure up somewhere. Does this model use a EGR cooler? Here's a testing method that can be used kzbin.info/www/bejne/h5etqqmwi7Z0f5Y Were there any resets that needed to be done after you did the belt and water pump? Are there any special bleeding procedures that need to be done? Do they have any auxiliary electric water pumps?
