It’s time for your 5-cylinder Volvo XC90 timing belt (interval PDF here), and you want to save some money and do it yourself. If you’re mechanically inclined and have worked on cars before, this will probably be not too difficult for you to complete. Keep in mind this tutorial is not only comprehensive and well […]
MVS Contributor Sledddriver goes on an multi-month blistering repair & fix odyssey, taking his 1998 V70 T5 from the edge of roadworthiness to 100% functional and reliable… all for not even $1000. This is Stage 0 and way, way more. Following up on Tryingbe’s theme [of restoring to 100% a P80 Volvo], here’s a list of sled-work […]
Volvo does not publish belt tension specs for “white” engines. The hydraulic tensioner took care of it and then the eccentric tensioners have the goalposts as marker for the correct tension range with engine cold.
The cast iron block 16 valve 4 cylinder had a spec of 4 but no unit was listed since the tool was provided by Volvo and it had no units on its face, just the numbers.
I worked for the manufacturer when that car was new and there was no information in any of the published info for technical personnel.
MVS Volvo Forums member Hobbs got a quote for almost $2500 to fix his XC90’s READ assembly. MVS Forums Contributor and all-around Volvo ninja jimmy57 explains what the READ assembly is, why it’s important, and what it does in XC90s. Rear Engine Ancillary Drive, READ, is the gearbox on side of engine that links crankshaft to the […]
kickin_it unleashes a beautiful writeup DIY with photos of how to change thermostat on Volvo XC90 T6 SUVs. I recently had the pleasure working on a 2004 XC90 T6. The issue at hand was a bad water pump so I replaced everything I took off: timing belt, accessory belt, tensioner, pulley, water pump, thermostat, and […]
Here is a legacy list of various 850 repairs I’m moving to the VRD, for posterity. Replacement of entire sunroof system Member, atikovi was having trouble with the sunroof not working properly and decided to go to a junk yard and retrieve an entire unit- frame, motor, cables, etc. He then documented (with pictures) how […]
Perhaps this may be obvious to the seasoned DIY’er’s or even some regular guys like me but after mulling it over and with the help of a couple of links I decided to tackle the Water Pump replacement by removing only the Hydraulic Tensioner. There were many other excellent links in the various Volvo forums (this one included) that some may find to be more helpful but the following provided me with the larger picture of what I needed to do.
How to balance cost with need on an old car – repairs. This is the Big Evil Meatball of car ownership IMHO.
There are so many ways to waste money on old cars I could write for weeks and not get halfway in Chapter One. In fact, we as a collective entity have done this, and we’re on Chapter two in decade two.
Installing a new water pump: 1. Start by ensuring that the engine block surface is clean and dry. Use a Scotchbrite cleaning pad to remove the old gasket material from the block. 2. Put the gasket on the block and then install the two bolts together with the waterpump to hold the gasket in place. […]
The TB (Timing Belt) with 85K on it is still OK, has hairline cracks, but time to replace.
The TB factory Idler and Tensioner Pulleys have slight play and were “free-wheeling”, so time to replace
The WP has no leak, but the bearing has a very very slight play. Technically speaking, you can keep the WP for another 30K. From reading Ozark Lee’s and few others experience with leaking WP at 150K or so, and since I have no time to redo this in 30K, I put in a new Aisin WP.
You want to do the valve seals while you’re at it. This is not an overkill because they are probably nearing the end of their life cycle and will develop oil seepage (just to make you feel regretful one day that you have to redo the gasket).
On another note, have you ever overheated the engine? Even if you haven’t, the mating surfaces for the head gasket need to be planed. There is usually a reason for the gasket to fail (and not always an apparent one).
