Owning a Rover SD1 means accepting that you will always have something to fix.
I’m a couple of days behind posting, thanks to near constant work on the Rover and MX5, but here we are.
On the weekend I decided to uncover the Rover so that I could use it, as the MX5 warrant was due to expire. I have booked the MX5 in for its warrant check, but its a couple of weeks until I can get it done. In the meantime the Rover will get all the use.
Of course being an SD1 I couldn’t just pull it out and drive it, no, I had to fix it first. Last time I drove it I noticed it rewarded me by leaking coolant from the expansion tank hose at the radiator, and the fuel hose on the fuel filter was once again causing me grief and cracking.
More of my lovely coolant spilled. Damn this car has a thing for coolant.
Undo two hose clamps and off comes the hose. Remember to remove the coolant cap first if you havent done so recently, or the system may still have pressure, as I found out; it makes a mess. Take a lot of care removing and refitting hose to the plastic bottle, as the hose barb can be very brittle and breaks off if you’re too rough. Then you’re in a world of pain.
I did originally buy some 8mm ID “coolant overflow” hose, but when fitting it occurred to me that the damn system is under pressure, as it’s not an overflow tank but an expansion tank, so overflow hose is useless. The hose needs to hold pressure.
It fits perfect and looks the part. I figure that unlike the fuel system if the hose does fail on here, I have a coolant level warning light that should give me some chance of killing the engine before going too far, and it’s not going to spray fuel everywhere and burn me to the ground.
Speaking of cracked. FML, I’m sick of replacing fuel hose now. This hose has been on the car less than 4 months.
I gave up on this hose as its rubbish, and went and purchased some proper branded hose from a local retailer. Unfortunately I can’t source 7.6mm hose locally, so had to settle for 7.9mm. This is R9 EFI rated (as the crap hose should be) and made by Codan in Denmark. This was available, on the shelf per meter from Supercheap Auto.
So with more fuel poured all over the place, on went the new hose. It fits quite well, but does need harder clamping pressure to seal tightly. No leaks, and by golly I hope it’s the last time I have to do those hoses.
I couldn’t see any of the cracking extending into the inner layer of rubber (the marks you see in the photo are from the knife), but the whole outer layer was trashed. I’m not sure if it would be a matter of time for the cracks to work their way into the inner layer, or if they stop there. I would rather just not find that out tbh.
Whilst in the engine bay I also fixed another source of my coolant loss. When I fitted my Speeduino I chose the wrong bolt to mount the CPS wiring bracket to. The bolt I chose goes right into a coolant gallery and never sealed properly with the bracket on the bolt. Whenever I shut the car down it would drop a single drip onto the belts. I knew about this for a while but since the leak was so minor I chose to leave it until I needed to actually add more coolant, and since I lost some from the expansion hose, the time was now.
I whipped the bolt out, removed the bracket and screwed the bolt back in. I moved the bracket to the bolt above, and problem solved. That bracket is looking a bit shabby now, so I might look into designing and 3d printing a new one.
I scored a couple of other good parts from the Whanganui haul, including a pair of decent shape chrome grille strips. My one was painted black by the previous owner, and before British Car Day I used chrome tape to make it shine again. Its nice from far, but far from nice. It did the job.
I’m not a fan of the fitment, so I went back to the standard orange lenses. I’ll have a think and see if there is any way to make it fit better.
Theres obviously a difference in how worn out my seal was too, as now the driver’s door is a little harder to close but seals a lot tighter. There is a noticeable reduction in wind noise too.
And then a lovely drive out to the south coast to watch the sunset with the Wife.
