Dad has amazing old school knowledge.

My neighbour told me good advice as a child when jacking up a car always use Axle Stands just in case the jack gives way as he sadly witnessed a co worker at the garage he used to work for crushed by a car , basically he said the co worker was in a rush to fix a customers car and cut corners disregarding his health and safety back in the 1960s and sadly dead at only 28 years of age not good. So good to see your dad had the health and safety in mind and put Axle stands under the car

Your dad's the biz ,what a knowledgeable chap 👍.

This video was fantastic!🤗 Your dad is a super knowledgeable bloke. And loved he just magically appeared all these clever tools and devices. 🔧👍 My suspect is the thermostat. Hence, it is stuck open and not allowing the car to get to the temp and mabye the coolant temp sensor as well due to fan running. I woukd also recommend replacing the coolant cap. A problem on many Rover models. I had to replace mine on my 1.4 K series 25 😊 I highly recommend (Discount MG Rover Spares) for all your Rover & MG Parts and are also fantastic for help and guidance to issues and common faults.

Interesting stuff! The thermostat is certainly suspect. Something to be aware of, apologies if you already know this, the temperature gauge on the 75 is non-linear. It'll sit at normal (9 o'clock) if the temp is anywhere between 75 and 105. The 75's trip display has an inbuilt diagnostic function that can give a numerical read out though! Google or search RU-vid for "Rover 75 diagnostic mode" for instructions, but the short version is: - hold down trip reset until a number appears - keep pressing trip reset till you get to 19 and stop - display will keep switching between l_off and l_on - press trip reset button once when it says l_off - keep pressing trip reset button till you get to 7 and stop - coolant temp will now be shown at the bottom of the display I used to use this on most journeys when I had a 1.8 75, just to keep an eye on things.

Spring retention plates were retro fitted under warranty to catch the spring when they broke.

He is really interesting to watch, on some occasions it's a bit annoying that he ignores your good questions but that's what dad's do I suppose. Probably not fully used to recording for an audience.

My experiences with locking wheel nuts is ditch them

Coolant caps were always an issue and were the first thing I used to check before pressurising the cooling system to check for leaks. On a couple of occasions, I found the leak was behind an exhaust valve due to a porous head which I discovered when I pressurised the cooling system then slowly turned the engine over while looking through the spark plug hole and noticed water dripping into the cylinder when the valve opened. Change the cap and bleed it properly before delving deeper to remove any doubt about the simpler things. Good luck

Jon, you sound a bit like David of Cruising the Cut which I'm putting down to your accent. You need to know a lot of stuff about Renaults because they're a nightmare to work on. I crakced up when your dad said "Your member gets corroded when it gets old".

The renault f9q diesel is the best diesel engine ever

Great video - Mark. !

From what I can tell, the Spring recall only effected the early cars (up to 2001) but not the Tourers. It seems they basically just powder-coated them due to issues with corrosion before when they were just a painted spring.

Put a u shape pipe on the heater hoses at the back of the engine to bypass the heater then see if the jiggle valve ball bearing is stuck up in the inlet manifold .its near the dipstick tube...then bleed the system...renew the o rings on the expansion cap... put silucone grease on them...then try again...Bob...Paignton....Good luck.....

Newark motors Crewe has been gone a few years now, great video guys.

My Dad was also an old school mechanic from the 70’s and 80’s and I used to go to work with him during the holidays. I barely learned anything but was mostly there to get tools while he was under a car, or to hold a lamp. It seems that we have similar ‘Paul Daniels’ levels of knowledge - not a lot

loved my 75 but yea i had a spring snap an dig in the tyre, 2 head gaskets but still had the car 9 yrs

Replacing expansion tank cap can also be a good idea, they sometimes fail.

Its a Getrag 5 speed manual Gearbox....Good Luck Jon....

New subsciber to your channel ,my friend had a rover we had a issue of it using water from what i can recall it was the inlet manifold causing the leak water was going into the inlet valves and being burnt of whilst driving.

Try firmly squeezing the top hose and see if u can hear the little ball bearing in the jiggle valve in the inlet manifold rattling.....

Fan running when the engine is cold: Faulty temp sensor for the ECU. Either the blue or the brown sensor. I cannot tell them apart. The way you described the temperatures floating around while you were on the road would point to thermostat

love your dad, end of comment!!!!!

Great video & wonderful how your dad magic’s up tool’s from no where

You can get replacement bonnet insulation pads from Rimmers… not expensive in themselves but the large packaging is. Did it on my 1.8, seems to be a failure due to overheating / steam… The front spring also went, there was a clip thing supplied later that stopped broken springs dislocating… I fitted them to mine.

Fantastic videos. Should have done combustion leak test

I love your dad

Maybe there was a huge air pocket in the system when you bought it and therefore you had weird temperatures and seemingly lost a lot of coolant? New thermostat after 20 years and sensor seem like a sensible thing to do too like someone else suggested.

Fab stuff

If it is an auto, i am sure it was a Jatco transmisson/ gearbox. Lovely car, used to own a 2002 Connoisseur SE CDTi

faut il acheter r75 que vaut le moteur et quelle modele prendre quelle probleme a cette voiture l embrayage ou pas les pieces sont t il cher on les trouve facile merci j atend votre reponse

faut il vraiment acheter r75 quel model prend et les probleme de cette voiture peut trouver les pieces merci d avance j attend votre reponse

As you have a head gasket kit. I would change it as a precaution. Heater matrix is full of crap. Pressure cap is suspect. I wouldn't rule out a cracked block.

The early cars had a 3-speed cooling fan controller (part of the fan motor), they were problematic as were the later 2-speed ones (the half-speed resistor for the AC only fails). I bet the coolant changes have been neglected and it needs a good flush or two with Wynn’s or similar…

Should of done the radiator gas test were by blue liquid turns yellow if yellow blown head gasket.

Was thinking thermostat or sensor faulty as Dad was thorough with the cylinder leakage test. Don't know anything about heater matrix. I assume you checked the fluids before setting off but may have been low.

P C , on spark plug, your could crawl through that gap, legend. Young petrol heads need to hang out with people like your dad and sponge up the knowledge.

I replaced the fan resistor on mine. It ran constantly until I changed it.

Would any garage be able to work in these nowadays?

Has the thermostat been removed to make it run cooler

love the75 but who couldnt resist an avantime

Good morning, you need to do a proper head gasket test with the coloured dye that changes colour , my money is on the shaft on the water pump has broken on the inside and the water isn’t being pumped around the engine, it’s getting up to temp then boiling over , or the thermostat but as long as the top and bottom rad house are hot then that’s ok , as for the heater matrix disconnect both pipes that run through the bulkhead to the matrix and put compressed air through the matrix

Avantime? do it!

We all do it, but where are the axle stands supporting that car?

Failed water pump?

Now don't take this personally, but it seems that all the videos getting great stats are those with your dad and your wife and crystal... 😂😂😂😂

Thermostat. Had all this with my old Volvo V40 and a new thermostat cured it.
