D24 Thermostat and Timing Kit
Hi, on the lookout for a Thermostat and Timing kit for my 1983 760 Turbo Diesel. I'm told to go for the 80 degree thermostat instead of the OEM 87 degree one. May someone please steer me in the right direction to find these parts. Wanting to get it back on the road ASAP. Thank you.

I don't know what exactly you mean by "timing kit"
I think you have to get all parts individually (idler, w pump, t belt etc) Careful with the waterpumps bc there are junk-quality brands out there. Try to find the good one. Tons of write-ups available on this Forum but I have no time to run the forum search right now. About the thermostat. I think I'll order this one and redo my cooling system for the Summer because it looks just like the 87Celsius WÄHLER thermostat that I recently installed but this one is the 80°C version. The 87degree version is fine btw and very safe to use (no issues with it for years but coming Summer I simply wanted a system checkup and a new unit) https://rover.ebay.com/rover/0/0/0?m...2F123005152200 |

Is this the correct timing kit to safely do the timing belt swap? |

Apparently the dial gauge extension housing has a second extension that, when assembled together provides enough length to attach a dial gauge forward of the vacuum pump. Otherwise, you will need to remove the vacuum pump.
The belt tension pin wrench: Does your engine have a belt tensioner? Additional tools you will need: Dial indicator Camshaft pulley lever (shown here) Additional tools that make for a much better experience: Dogleg wrench (for tight space rear camshaft pulley bolt)(also shown here) Others are encouraged to list their favorite versions. Some have found suitable on ebay.

About the thermostat, I live in New Zealand where on average the temperatures range from 10 - 25 degrees Celsius, sometimes colder or hotter. Should I get an OEM 87 degree thermostat or go for the 80 degree one so I know that my engine will be running cooler. Thanks |

Seems like I answered this question recently. My FLAPS has them, like $13? Maybe yours can order one for you? If not, try Rockauto, they have Contitech brand.
More importantly, where are you going to obtain the necessary special tools? Even though your WP is good, moving it to detension and retension the TB can cause the old o-ring to leak, so best to replace that as insurance.

80C thermostat will be the best choice in your climate, or any other scenario of prolonged operation in hot weather involving high speeds or hills.
For a "complete" timing belt service on this engine or any other engine like it, the rule of thumb is to replace the timing belt and any service parts it touches. For a D24 or D24T that means the timing belt, the idler roller, and the water pump. Even if the water pump is "good" for now (meaning no leaks, bearing OK), if the bearing goes bad later on within the life of your new belt, then it'll take the belt out and the rest of the engine with it. (Or if you're lucky you'll notice it first, but then in order to replace the water pump, you will have to do most of the timing belt job again.) Therefore, the logic is to replace these parts as a system so that everything remains trouble-free until the next routine service interval. The rear timing belt, which drives the injection pump, should be replaced as well since it is removed during the front timing belt service. As ngoma wrote, though, there's no point in buying the belt parts unless you have a plan for how you will successfully install them. The required special tools and procedures are mandatory. You WILL NOT be able to replace the timing belt successfully without them. If you try, your best case is that the attempted belt replacement will be extremely difficult and, if you manage to get the engine running again, it will start and run poorly. Other, more dire (but common!) outcomes are that you may not ever succeed in getting it running again, and/or the engine will be destroyed by a sheared crankshaft gear. Replacing the timing belt proactively is necessary because if it breaks the engine will be ruined. BUT incorrect installation of the belt can be just as destructive. Those are the warnings. But here is the good news: with the correct tools and process, replacing the timing belt is a straightforward job and you won't have to do it again for many years. The tools are specialized but not that hard to acquire. Volvo dealers still sell them, or other owners may have sets they will share. Here on this forum, members often loan tools to each other for this work. Many also have had good luck borrowing or buying these tools from independent Volvo specialist garages, or from Audi or VW specialists who deal with the 5cyl version, or on ebay. As for the procedures, the official Volvo instructions for replacing the belt and associated components can be found in the "greenbook" repair manuals which are available for free online in various places. If you can't find one, post back and folks will point the way. There are also instructions and tips posted throughout the forum here that can serve as an alternative or an addition to the greenbook procedure. Any questions you have that you can't find by searching, just start a thread and ask.

Thanks V8volvo. I found a site called autodoc.co.uk that gave me all these options for a water/timing kit to buy from different brands. Is this a known site and can be trusted, and if so what is the go to brand for replacement parts? I've heard and seen a lot of "Gates" items around. About the timing kit replacement, I have got no other signs to replace other than people telling me to replace it so I know that it's good. Tool wise, I don't have any and down here in New Zealand, they may be hard to get. I've got the full collection of green books for the 760 GLE and GLE Turbo Diesel - bought them from someone who sold his 740 TD, so I've got all the books necessary which is awesome. About the thermostat, I will look out for a 80C one. I found one on the autodoc.co.uk site from a brand called MEYLE, but it was out of stock. |
