Bit of DIY stuff on the MX5 this morning
Replaced aux belt tensioner, idler pulley and the belt, as mine had started to rattle slightly, wasn't sure which part it was but figured on a 7 year old car might as well replace all items whilst its apart.
Eurocarparts wanted over £220 for all the bits (lol), MX5parts £205, where as there is a Gates kit that contains all of the parts together that can be had for under £90 online. Gates belts and pulleys are good quality parts, they are the OEM for many companies, so it made no sense to spend more. I followed a guide on Miata.net, haven't done this before but only took 45 minutes or so. Battery out and you get access...spot the shiny new bits...
New belt on...gonna buy myself a 3/8 breaker bar, my 1/2 one wouldn't fit on the tensioner due to the depth (it needed socket adaptor which meant it wouldn't fit on), slackening off the tensioner with a short spanner and trying to put the belt on is a bit trickier...
Also bit of preventative maintenance, the wiring to the coil-on-plugs is subject to heat and vibration and can crack, causing misfires and necessitating replacement of part of the engine loom. Some DEI heatshielding wrap may help prevent this happening on my car...once the engine cover is on its totally invisible.
Been for a drive, the slight rattle is gone, checking the old parts and the idler pulley's bearings were on its way out and a bit rough.
