I am in the process of replacing my radiator because of a leak on the driver's side tank where the fan shroud bolts. I am assuming that the incorrect bolt was used by a previous owner or mechanic and the driver tank cracked. I assumed that the bolt/screw on the passenger side was factory correct, until I went to the dealer. The dealer told me the bolt should be part number FS106127L. The parts guy looked it up in the system and confirmed the location of the bolt with me. I have attached a few pictures. One shows both bolts (dealer and my factory original assumption) to compare. The other picture is the bolt location on the radiator as if you are standing in front and looking at the top of driver's side tank. I do not want to crack my new radiator with the wrong bolt.

My question - Can anyone tell me which bolt I should use or the correct bolt part number?


Thanks!

Use the dealer one.

 

My radiator has a leak from the same exact place and the "Screw" that was in mine is the same exact one you had in yours.

What are the chances that both of our Previous Owners used the same exact wrong screws?

I am wondering if these phillip head screws came from the factory and then were a problem and changed at some point and my rover was never updated.
Can someone else with a D2 take a look at the bolt/screw on top of the radiator and let me know which one you have?

Thanks

 

I think I recall someone saying there are different length screws in that same general area and that if someone put the wrong on in the radiator it will pierce the top tank. Not sure if that's true, but it is pretty common for them to leak at that screw.

 

My tank cracked in the same place and had the philips head screw in it. I think the main problem is that sticking a steel screw into plastic that cycles through such wide temps is a very British design (prone to leaking). Mine cracked on the side of the screw hole, not the bottom so the screws weren't too long. I put mine back together with the screws but I'm going to switch to some other mounting technique.

 

I put the dealer screw into my rad.
But, you don't have to.
You could probably put a metal self taping screw in too.
The screw they use is like a wood screw - really bites into the radiator.
If you put it in too tight, you crack and older heat stressed radiator and end up with a leak there.

 

Gasket sealer on the threads before replacing sound like a good idea?

 

JB Weld a short piece of all-thread into the hole?
