Step 8 - After a lot of cursing and fiddling, I gave up with the universal O ring set I had and re-used the o ring off the old stat. This is not ideal although won't really do any harm. I recommend you get a new one. The o ring fits around the outside of the stat (you can see the ring where it...

Step 5 - Pull the housing forwards (there should be little resistance), and you reveal the thermostat. Note the recess that the stat sits in with an o ring seal around it. While we're on the subject of thermostats - Don't run without a thermostat, it is there for good reason. It is important...

Step 3 - This picture is taken from underneath the car and shows the drain tap for a Fluidyne rad, the stock rad has a similar tap. Undo this and coolant will come out the centre as shown in the second picture Step 4 - Whilst the coolant drains, head back up to the thermostat housing...

Step 1 - Remove the rad cap. Note I have a Fluidyne rad so don't worry if yours is thinner and black, that's a stock radiator IMPORTANT : Never remove the rad cap on a hot engine, the coolant is kept under pressure so that it can reach temperatures in excess of normal boiling point, if you...

The coolant system on the 7M is a POTENTIAL weak point. If properly maintained, you have far less chance of having problems which may lead to a blown head gasket. You should inspect hoses regularly and any that show signs of cracking or have become brittle should be replaced immediately...

Step 8 - Crack open your new sensor and see what you have. Be aware that generic ones will probably come with just bare wires for you to terminate on your existing connector. The picture shows what I received - the sensor and 3 'bullet' connectors. Be very careful with the sensor and make sure...

GUIDE : Changing your Lambda sensor I recommend you get the Lambda sensor and adaptor flange from somewhere like buypartsbuy.co.uk (http://www.buypartsby.co.uk/lambda_sensors.php), and it should cost you about £35 delivered. You want a 3 wire generic sensor. I'm not going to cover the TSRM...

Step 26 - Another 6 or so coats later and it's like this Step 27 - Another wet sand to get the surface finish we are after Step 28 - Always dry the bits off after wet sanding with some clean kitchen towel. This will prevent staining from watermarks Step 29 - Sadly I lost a...

Step 10 - Go to 9 for at least 3 or 4 coats. I decided 8 coats to start with, then some more stopper/filling then another 8 coats. That's just the primer of course. Hycote stuff allows 10-15 minutes between coats so within a couple of hours you can have built up a nice covering. Afetr 8 coats...

Disclaimer : I'm not a sprayer or bodywork specialist but I've done this stuff a few times. I don't know if this is 'the done thing' or considered good practice but I base it on the results. I'm happy enough with the work I'm doing to put this up as a guide and if you like the results then use...

Step 12 - You'll find a plastic cover on the base of the filter, this protects the seal which is usually pre-greased. Remove this and try to make sure you don't get any grit/dirt etc on the face of the filter. If you do then clean it thoroughly or you'll have a poor seal and leakage Step...

For those of you who don't know, turbo charged vehicles need frequent regular oil changes. Neglect this at your peril - seriously. Don't cut corners when it comes to changes, use a decent oil (No need to get carried away but avoid the £3 chip fat varieties!), always do the filter and use a...

Step 6 - Once you have successfully confirmed the end pieces will fit the car you can bolt them down with the original nuts. Be sure to torque them down progressively, don't just do one bolt up tight then the next because you will stress the metal for no good reason, just go round them gently...

A strut brace is designed to add extra strength to the car when turning forces are applied. The vehicle is subject to great stresses when cornering (especially at speed) and the whole chassis flexes and moves. By joining the tops of the suspension turrets with a hardened metal bar, the flexing...

Question are the connections you mention (E2 IDL VTA and V2) going from bottom to top? if i use your settings with E2 being the bottom one, i can get a match , but not if its the top. I have a auto 1990 turbo. Answer Yes!

Step 11 - Loosten but don't remove the two screws to the TPS so you can move it about Step 12 - Insert a 0.7mm (for the 7MGTE, use 0.58 for 7MGE) feeler gauge between the throttle stop and lever then connect to terminals E2 and IDL .You need to turn the TPS fully anti clockwise until you...

The throttle position sensor can make a massive difference to the way your car performs. If it is out of calibration you may find you can't set the timing up prpoerly and it will change throttle response significantly. It's a bit of a pain to set up but well worth it in my opiniong (Having...

Checking and adjusting your valve shims is something you should do as routine maintenance. If the shims are wrong you can lose power and increase emissions, check them! It's a fiddly job and you need a friend but it might well make a big difference to your car. I found EVERY single shim was...
