Water in foot well- any advice please
Discussion
Guys
I am after some advice, following from finding water in foot-well in my garaged 1989 S2 and none in the cooling system. I've checked all pipes and connections and all looks ok. The only part I cant check without dismantling the dash is the heater and its matrix, but I think that's the problem.
I am guessing the heater matrix is shot, and hence leaking. I know to change this requires a complete dash removal, but before I start doing this can I ask the following -
1) Can I get a new heater/ repair the heater matrix , if so where from and approx cost?
2)I only use my S2 in summer, hence no need for a operational heater, therefore is there a quick/ easy way to bypass heater without causing any engine over heating problems and removal of the dash?
Any advice will be greatly appreciated.
Thanks
Dan

Bypassing the matrix or stopping off either end wouldn't cause much difference to the warm up time or running temperature as the system has an isolator valve controlled by the slider thing on the dash anyway.
If you did choose to run without a heater a load of pipe would be redundant and so could be removed
I bet you could make a weight saving of at least 1kg

You should be able to by-pass the heater by finding where the two pipes go into the bulkhead and simply cutting and joining them. I only use mine in the summer but a heater is still useful to de-mist the screen if it rains.
I'm only guessing here, but I'd have thought a radiator re-coring firm should be able to re-core a heater matrix. After all it's just a small radiator. It may be best just to bite the bullet and remove the dash and do the job properly. You'll find lots of other little jobs to do behind there while it's off

........Try DCThermal.com....
Hum.. On the face of it this seems like a very sensible mod, especially for cars which only come out in the summer months. It would also do away with a lot of pipe-work and cut down little leaks making the cooling system more efficient. Thoughts? Pros/cons?

Some on Amazon have pretty poor reviews. No experience myself.

...At 50A current it would need some serious cabling and switching!.........
this is the cable shown on the website. So about the same gauge as starter motor cable? Running that from a front mounted battery to behind the dash shouldn't be too much of a problem. You'd need a relay to switch it obviously but from an electrical perspective this should be quite easy.phillpot said:
..... and you wouldn't want too leave it on for long without the engine running...
Or with the engine running... you might melt the dash! This was one of my 1st TVR tasks.
As ever some bits are easy (whip the radio out, remove steering wheel & cowl, find the fixings for the dash and undo, pull forward....then get the heater box out and hey presto......you'll need to cut the box to extract the matrix.
my matrix was a rare weirdo from an air-con development trial?!?!?! but most are either re-core-able by local radiator repair types or can be purchased from tvr spares people:
In the short term a bypass is easy... just link the two pipes going through the bulkhead with a connector.
