g0ldf1ng3r 15 Posted November 28, 2017 Hello again all this time im asking for help on my valver, 1990 1.8 16v i think ive located my oil leak - seems to be coming out of the top of the oil cooler, between the cast part & the metal cooler ive got an O ring on order, the one that sits between the 2 bits mentioned above ive looked at what i think is a schematic of the cooler but thought id ask if anyone knows how they come off? it looks like i remove the oil filter & then there is a nut that holds the cooler on via a central shaft i guess i undo that, unclip that feed & return hoses & then slide it down any input would be appreciated thanks Quote Share this post Link to post Share on other sites
VEEDUBBED 0 Posted November 28, 2017 That's basically it mate, I'd also unscrew the center threaded shaft as it makes it easier to relocate the cooler and the orings. Ideally i'd fit a proper Mocal or similuer cooler and get rid of the original version, they are known to break and make a huge mess when the oil mixes with the cooling water..

g0ldf1ng3r 15 Posted November 28, 2017 on the point of servicing - anyone know how much oil the 1.8 16v takes for an oil change? hopefully not just over 5 litres like the VR lol Quote Share this post Link to post Share on other sites

lesarcsneil 0 Posted November 28, 2017 From memory the nut that holds the oil cooler on is in the region of 24mm (but could be as big as 28mm). If you measure up and get the correct sized deep socket it makes the job a lot easier, especially getting the correct torque on reassembly. An oil change on a 2.0 16v is normally 4 litres, I'd imagine a 1.8 is similar. Neil Quote Share this post Link to post Share on other sites
g0ldf1ng3r 15 Posted December 7, 2017 can anyone tell me what size the nut is that holds the oil cooler on pls? one place is saying 24mm but another says 27mm - both of which are bigger than those in my socket set so will need to buy one for this job Quote Share this post Link to post Share on other sites
VEEDUBBED 0 Posted December 7, 2017 Your gonna need that socket the long/deep variety too, no way a normal socket will clear the threaded pipe bit. Tomorrow morning I'll measure a few I have spare but 99% it's a 24mm size. Quote Share this post Link to post Share on other sites

VEEDUBBED 0 Posted December 9, 2017 Right, i've Got a few spare 'raddo engines in bits. Both late 2.0 valver 9A's have a 27mm nut holding the cooler in place but the other older KR mill has a 24mm version. Disregard what I said about the deep socket, I needed that when I fitted a Volvo oil cooler onto my turboed 16v years back, you'll be fine with a normal socket.
