Re: Coolant catch tank

The other modification that really helps (at least on a Rover V8) is to have a modified thermostat housing. The original Rover one angles up too much and causes the hose to kinks up over the distributor so you get a high point in the hose which is higher/equal to header tank. I dont think this matte...

Re: Coolant catch tank

Hi Clive thanks, I agree that once it's reached the correct level it shouldn't spurt any more coolant out but my main issue is i would like to see the level of the coolant and ensure it isn't ejecting any more so all i have to worry about is minimal evaporation. On the rad cap, that's interesting as...

Re: Coolant catch tank

Hi, I was initially confused but now (I think) understand. - Basic system as fitted to HAwk using Gerry's aluminium cylindrical expansion tank. This has a pressurised rad cap on it. It should be filled to half way up the cylindrical tank to allow for coolant expansion when it heats up. If you overfi...

Re: Coolant catch tank

Wow.... thanks Peter, i might be able to manage that mod but I think Migge's is somewhat beyond my metal bashing capabilities. Out of interest what pressure rad cap do you all use?

i have seen 10psi, 13psi and 15 psi.
thanks stuart

Re: Coolant catch tank

Hi I have also experimented with sealed system overflow tank. - i agree the outlet pipe from Gerry's header tank was not airtight (it was never designed to be) so unless you're lucky it will need welding up before fitting pressurised overflow tank. - do you have any pictures of the radiator cowling ...

Re: Silverstone Classic 2019

I have booked for Sunday at Silverstone. My hawk UBD163G was supposed to be there but I think it’s too far to push. I hope to still get there but probably in something German (and boringly reliable!)

Re: Header tank radiator cap

Hi Peter
yes Stag is perfect it has inlet at bottom, you can see the water level. In have ordered the TVR straight housing as it looks like it will fit. I will update when it arrives!

thanks again for your help

Re: Header tank radiator cap

Hi Peter thanks. i was thinking of making it a closed system and have sourced a Stag expansion tank which looks like it will do job. looking at Gerry's header tank i think the current overflow pipe will need welding/beefing up as it already weeps around joint which doesn't matter in current set-up b...
