Shop diagnosed my engine cooling pump as the issue and quoted $1,400 for parts and labor. I’m planning to do this myself instead — pump is a 5-bolt electric unit (AISIN WPT-191 / Toyota 161A0-39025), no belt or pulley involved.

My plan: pull her up onto my ramps, drain coolant, disconnect the electrical connector, pull the 5 mounting bolts, clean the mating surface, install the new pump with the gasket it comes with, reconnect, refill with Toyota Super Long Life coolant, bleed the system. It’s gonna be a tight squeeze, but I should be able to get it as I’ve seen several others not have to takeoff the front tire.

I’m not a mechanic but I’ve watched several videos and feel fairly confident on the mechanical side. A couple questions for anyone who’s done this on the same generation (2012–2017 AVV50):

1. Anything commonly missed or that catches people off guard on this specific job?

2. The shop didn’t give me a code, just said “engine cooling pump.” Since I wasn’t told about any codes for the radiator hoses or coolant temp sensor, should those be assumed fine, or is it common for those to fail silently alongside the pump?

3. Any tips on bleeding the system properly on this engine to avoid air pockets?

4. Do I actually need a torque wrench for the mounting bolts since they thread into aluminum, or is careful hand-tightening with a regular wrench good enough?

Thanks for taking time to read this and I appreciate any input from people who’ve actually done this one.

Some animal chewed through the wiring near my front turn signal. The wires were bitten off too short at the plug to splice, so I need to buy a new connector rather than splice the existing one.

The plug is stamped “11349” and only has 2 of its 3 positions wired from the factory. Found what looks like the same shell being sold as a “3-way alternator connector” for a Mazda 6 — seems like this housing might be a generic/universal plug shared across multiple applications rather than something turn-signal-specific. I believe it is just a an additional plug for ease of disconnecting rather than having to cut wires every time you need to take out the headlight housing.

Can anyone confirm what this connector is actually called, and whether it’s fine to use a standard 3-wire version (using 2 of the 3 wires, capping off the third) as a replacement? Thanks in advance for your time.

I have a 1984 Yamaha QT 50 and I want to covert it to electric. I’ve been having a lot of issues with it in regard to the engine and wiring harness. Just wanted to see if anyone on here has done this, or knows about how someone would begin this journey??? Anything would help. Thank you for your time!
