Can anyone help with the correct Engine ECU part number for my 1986 efi 3.5 automatic UK spec Vogue with Air Conditioning (now removed). My LR parts book states PRC 7440 but it is fitted with a PRC 4764, which I beleive is the original. I need to locate a replacement as I have fried the EFi...

Have you checked the radiator for a blockage, if it is, it may be causing a hot/cold spot that a sensor is picking up and feeding the engine ecu with incorrect engine fuel requirements. Thus causing mis-firing and bad starting when hot. Good luck

About 4 hours from you, near Luton Airport.

Thanks for all your replies and suggestions, I will seek out a manifold and carbs.

Thanks for the rapid response, what about the wiring for all the sensors and ecu? Mine is an auto, will this be just as easy do you know?

Having fried what seems most of my 3.5 efi electrics and getting no where trying to fix the problems, how easy is it to change to a carb set up?

Rick the Pick It does about 10 mpg around town and 12ish on a run. But I know it needs a new cam & followers ect and it does have BIG tires on. Have you ever had experience of having an ECU repaired? New AFM arriving today-fingers crossed.

Ooops, sorry Pete1987RRC, thanks for the offer.

Thanks to all for you replies and comments. Zen I am near St Albans Hertfordshire. A little distance from you, but many thanks fror the offer.

Before I go in to complete melt down about a running issue with my 1986 RC 3.5 efi I thought I would seek the help from the experts. I did a very silly thing when welding the inner wing on my RRC, I connected the welder earth lead to the water pump. The battery was disconnected, I now have an...

I have fitted the ERC675 which according to the various sites is the correct one, but it is 937mm X 12.7.

Good afternoon and Happy 2015. Can anyone out there provide the correct part number for the PAS belt on a V8 EFi 1986 auto Classic. I have fitted the widely stated ERC675 but is is to loooong. Found 614106 in a parts guide but suppliers cross reference it back to ERC675. My RRC has A/C and a...

Norseman thank you for your reply. I have since found out that the 1987/1988 model year RRC had a mix of different radiators, pipes and expansion tanks on the 3.5 V8. I am going to try a NTC5632 pipe tomorrow to see if it fits ok. If not I will get the old radiator - re-cored and return or sell...

Well today was going to be a positive day, but as usual being the owner of a RRC it was not. Bit the bullet last week and ordered a new cooling radiator after looking at my CD parts manual (ESR80) for my 1986 RRC 3.5EFI Auto. Tried to fit it this afternoon and it is: 1, About 8mm taller. 2, Has...

Many thanks to you all for the replies. Do you know how many rows on an aftermarket unit I would need.

Can anyone help me with the replacement of the auto gearbox oil cooler on my 1986 RRC. Believe it or not it has rusted through from the outside in!!! I am finding it difficult to find a serviceable used replacement. Is it possible to fit an aftermarket one and if so how big does it need to be...

EeEk many thanks for your reply. Is it a straightforward job apart from the items mentioned? Is it just a case of fitting blocks on the existing body mounting points and moving the bumpers, some one posted about the radiator needed lifting. Really appreciate your reply. Thanks

Having searched the forums can anyone inform me of what would be required and how easy is it to carry out a Body Lift on a 1986 RRC? I am wishing to fit bigger profile tyres to get more clearance under the diffs. Many thanks

Thanks for all the comments and information. Both of the rear load space floor supports are formed from sheet metal and are a top hat shape in cross section. At both ends of each support is a tubular upstand of about 20mm that is welded in place , the securing bolts go through near the wheel...

Thank you for your reply. I have seen aftermarket ones from a number of online well know suppliers and ALL are missing the tubular upstand (which I can weld on). But they will not say they will fit as the are made for welding on, not screwing in place as mine are. I may be missing the point...
